Abstract:
Stimulating antibodies against G-protein-coupled receptors, including the β1- and β2-adrenergic receptors, the α1-adrenergic receptor, and the angiotensin II AT1 receptor, have been described, as well as activating antibodies directed at the platelet-derived growth factor receptor tyrosine kinase. Their existence and actions appear to be established. Lacking are mechanistic studies of receptor activation and translational studies to document receptor-stimulating antibodies as worthwhile therapeutic targets.

Abstract:
Abstract N-methyl-D-aspartate (NMDA) receptors belong to ionotropic glutamate receptor family, together with α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors, kainite receptors and δ-receptors. All of these receptors are tetramers composed of four subunits. NMDA receptors have several unique features in relation to other ionotropic glutamate receptors: requirement for simultaneous action of two coagonists, glutamate and glycine; dual control of receptor activation, ligand-dependent (by glutamate and glycine) and voltage-dependent (Mg2+ block) control; and influx of considerable amounts of Ca2+ following receptor activation. Increasing number of researches deals with physiological and pathophysiological roles of NMDA receptors outside of nerve tissues, especially in the cardiovascular system. NMDA receptors are found in all cell types represented in cardiovascular system, and their overstimulation in pathological conditions, such as hyperhomocysteinemia, is related to a range of cardiovascular disorders. On the other hand we demonstrated that blockade of NMDA receptors depresses heart function. There is a need for the intensive study of NMDA receptor in cardiovascular system as potential theraputical target both in prevention and treatment of cardiovascular disorders.

Abstract:
Extracellular nucleotides have been implicated in a number of physiological functions. Nucleotides act on cell-surface receptors known as P2 receptors, of which several subtypes have been cloned. Both ATP and ADP are stored in platelets and are released upon platelet activation. Furthermore, nucleotides are also released from damaged or broken cells. Thus during vascular injury nucleotides play an important role in haemostasis through activation of platelets, modulation of vascular tone, recruitment of neutrophils and monocytes to the site of injury, and facilitation of adhesion of leucocytes to the endothelium. Nucleotides also moderate these functions by generating nitric oxide and prostaglandin I2 through activation of endothelial cells, and by activating different receptor subtypes on vascular smooth muscle cells. In the heart, P2 receptors regulate contractility through modulation of L-type Ca2+ channels, although the molecular mechanisms involved are still under investigation. Classical pharmacological studies have identified several P2 receptor subtypes in the cardiovascular system. Molecular pharmacological studies have clarified the nature of some of these receptors, but have complicated the picture with others. In platelets, the classical P2T receptor has now been resolved into three P2 receptor subtypes: the P2Y1, P2X1 and P2TAC receptors (the last of these, which is coupled to the inhibition of adenylate cyclase, is yet to be cloned). In peripheral blood leucocytes, endothelial cells, vascular smooth muscle cells and cardiomyocytes, the effects of classical P2X, P2Y and P2U receptors have been found to be mediated by more than one P2 receptor subtype. However, the exact functions of these multiple receptor subtypes remain to be understood, as P2-receptor-selective agonists and antagonists are still under development.

Abstract:
P2X receptors are ATP-gated cation channels that mediate fast excitatory transmission in diverse regions of the brain and spinal cord. Several P2X receptor subtypes, including P2, have the unusual property of changing their ion selectivity during prolonged exposure to ATP, which results in a channel pore permeable to molecules as large as 900 daltons. The P2 receptor was originally described in cells of hematopoietic origin, and mediates the influx of and and and ions as well as the release of proinflammatory cytokines. P2 receptors may affect neuronal cell death through their ability to regulate the processing and release of interleukin-1, a key mediator in neurodegeneration, chronic inflammation, and chronic pain. Activation of P2, a key mediator in neurodegeneration, chronic inflammation, and chronic pain. Activation of P2 receptors provides an inflammatory stimulus, and P2 receptor-deficient mice have substantially attenuated inflammatory responses, including models of neuropathic and chronic inflammatory pain. Moreover, P2 receptor activity, by regulating the release of proinflammatory cytokines, may be involved in the pathophysiology of depression. Apoptotic cell death occurs in a number of vascular diseases, including atherosclerosis, restenosis, and hypertension, and may be linked to the release of ATP from endothelial cells, P2 receptor activation, proinflammatory cytokine production, and endothelial cell apoptosis. In this context, the P2 receptor may be viewed as a gateway of communication between the nervous, immune, and cardiovascular systems.

Abstract:
Adenosine and its receptors exert a potent control on the cardiovascular system. This review aims to present emerging experimental evidence supporting the existence and implication in cardiovascular disorders of specific adenosinergic pharmacological profiles, conforming to the concept of “receptor reserve”, also known as “spare receptors”. This kind of receptors allow agonists to achieve their maximal effect without occupying all of the relevant cell receptors. In the cardiovascular system, spare adenosine receptors appear to compensate for a low extracellular adenosine level and/or a low adenosine receptor number, such as in coronary artery disease or some kinds of neurocardiogenic syncopes. In both cases, the presence of spare receptors appears to be an attempt to overcome a weak interaction between adenosine and its receptors. The identification of adenosine spare receptors in cardiovascular disorders may be helpful for diagnostic purposes.

Abstract:
Insulin acts within the central nervous system through the insulin receptor to influence both metabolic and cardiovascular physiology. While a major focus has been placed on hypothalamic regions, participation of extrahypothalamic insulin receptors in cardiometabolic regulation remains largely unknown. We hypothesized that insulin receptors in the subfornical organ (SFO), a forebrain circumventricular region devoid of a blood-brain barrier, are involved in metabolic and cardiovascular regulation. Immunohistochemistry in mice revealed widespread insulin receptor-positive cells throughout the rostral to caudal extent of the SFO. SFO-targeted adenoviral delivery of Cre-recombinase in insulin receptorlox/lox mice resulted in sufficient ablation of insulin receptors in the SFO. Interestingly, when mice were maintained on a normal chow diet, deletion of SFO insulin receptors resulted in greater weight gain and adiposity, relative to controls, independently of changes in food intake. In line with this, ablation of insulin receptors in the SFO was associated with marked hepatic steatosis and hypertriglyceridemia. Selective removal of SFO insulin receptors also resulted in a lower mean arterial blood pressure, which was primarily due to a reduction in diastolic blood pressure, whereas systolic blood pressure remained unchanged. Cre-mediated targeting of SFO insulin receptors did not influence heart rate. These data demonstrate multidirectional roles for insulin receptor signaling in the SFO, with ablation of SFO insulin receptors resulting in an overall deleterious metabolic state while at the same time maintaining blood pressure at low levels. These novel findings further suggest that alterations in insulin receptor signaling in the SFO could contribute to metabolic syndrome phenotypes.

Abstract:
The mineralocorticoid receptor (MR) and glucocorticoid receptor are ligand-activated transcription factors that have important physiological and pathophysiological actions in a broad range of cell types including monocytes and macrophages. While the glucocorticoids cortisol and corticosterone have well-described anti-inflammatory actions on both recruited and tissue resident macrophages, a role for the mineralocorticoid aldosterone in these cells is largely undefined. Emerging evidence, however, suggests that MR signalling may promote pro-inflammatory effects. This review will discuss the current understanding of the role of corticosteroid receptors in macrophages and their effect on diseases involving inflammation, with a particular focus on cardiovascular disease.

Abstract:
Purinergic G-protein-coupled receptors are ancient and the most abundant group of G-protein-coupled receptors (GPCRs). The wide distribution of purinergic receptors in the cardiovascular system, together with the expression of multiple receptor subtypes in endothelial cells (ECs) and other vascular cells demonstrates the physiological importance of the purinergic signaling system in the regulation of the cardiovascular system. This review discusses the contribution of purinergic P2Y receptors to endothelial dysfunction (ED) in numerous cardiovascular diseases (CVDs). Endothelial dysfunction can be defined as a shift from a “calm” or non-activated state, characterized by low permeability, anti-thrombotic, and anti-inflammatory properties, to a “activated” state, characterized by vasoconstriction and increased permeability, pro-thrombotic, and pro-inflammatory properties. This state of ED is observed in many diseases, including atherosclerosis, diabetes, hypertension, metabolic syndrome, sepsis, and pulmonary hypertension. Herein, we review the recent advances in P2Y receptor physiology and emphasize some of their unique signaling features in pulmonary endothelial cells.

Abstract:
Trace amines (TAs), including p-phenylethylamine (p-PEA), tyramine and octopamine are structurally and functionally related to biogenic amines such as catecholamines and serotonin and to amphetamines. They are present in trace levels in the nervous system and in chocolate, cheese and wine. TAs are usually regarded as indirectly-acting sympathomimetic amines (ISAs) exerting vasoconstriction via a-adrenoceptors. However, they also stimulate trace amine-associated receptors (TAARs), of which only TAAR1 and TAAR4 are sensitive to TAs. The aim of the thesis was to examine whether vasoconstriction by TAs in blood vessels is via ISA or TA mechanisms. TAs caused concentration-related and endothelium-independent contractions in rat isolated aortic rings in the presence of prazosin (ai-adrenoceptor antagonist), cocaine (catecholamine uptake inhibitor), ICI-118,551-adrenoceptor antagonist) and pargyline (MAO A and B inhibitor). The persistent and inhibitor-independent contractions suggest that mechanisms other than ISA and a- and p- adrenoceptor stimulation are involved, possibly TAARs. Differences in the profile of vasoconstrictor activities to a range of TAs were identified in rat and guinea-pig aorta, suggesting species variations in receptor distribution. Tyramine was identified as a partial agonist in isolated rat aorta and an antagonist of other TAs in this tissue. Finally, the presence of TAAR1 mRNA and protein was demonstrated for the first time in rat aorta by RT-PCR and Western blotting, respectively. Most information about TAs relates to studies which have been done on the brain, or cloned receptors expressed in transfected cells. This study of different TAs and structurally related derivatives in aortic tissues has expanded the knowledge of the vasoconstrictor effects of TAs in isolated tissues. The molecular biological confirmation of the presence of TAAR1 and the pharmacological findings regarding the effects of TAs in rat aortic rings might explain their hypertensive effects and their role in coronary heart disease and migraine headache.

Abstract:
Les maladies cardiovasculaires restent la première cause de mortalité et deviennent vite la préoccupation de santé numéro un dans le monde. L'identification de nouveaux facteurs responsables de la régulation du système cardiovasculaire et la génération des modèles animaux des maladies cardiovasculaires sont des étapes importantes pour mieux comprendre les pathologies de l'insuffisance cardiaque incluant les maladies cardiaques congénitales et pour développer des nouvelles thérapies. Les prokinéticines sont des facteurs angiogènic potentiels qui se liant aux récepteurs couplés aux protéines G (PKR1 et PKR2) pour initier leurs effets biologiques. D'abord, nous émettons l’hypothèse que la voie de signalisation du récepteur 1 de la prokinéticine (PKR1) peut contribuer à la survie des cardiomyocytes ou à la protection du coeur après un infarctus du myocarde. Puisque nous avons montré que la prokinéticine-2 et PKR1 sont exprimés dans le coeur des souris adultes et dans les cellules cardiaques, nous avons étudié le rôle de la prokinéticine-2 et PKR1 sur la fonction des cardiomyocytes. Dans les cardiomyocytes et les cellules H9c2, la prokinéticine-2 ou la surexpression de PKR1 active Akt pour protéger les cardiomyocytes contre le stress oxydatif. Puis nous avons déterminé si le transfert de gène, ADN codant PKR1, intracardiaque peut améliorer les fonctions du myocarde après l'infarctus du myocarde dans le modèle de souris. Le transfert transitoire du gène PKR1 après ligation de l’artère coronaire réduit la mortalité et préserve la fonction du ventricule gauche en favorisant la néovascularisation et en réduisant l’apoptose des cardiomyocytes. Nos résultats suggèrent que PKR1 peut représenter une cible thérapeutique originale pour limiter les lésions du myocarde suite à une ischémie. Ensuite, nous avons déterminé les conséquences pathologiques suite à la surexpression de PKR1 dans les cardiomyocytes in vivo. Nous avons généré des souris transgéniques surexprimant PKR1 dans les cardiomyocytes (TG-PKR1) en utilisant le promoteur α-MHC. Les coeurs TG-PKR1 ne montrent aucune anomalie spontanée dans les cardiomyocytes, mais on observe une augmentation de la densité capillaire et des artérioles. De plus, en surexprimant PKR1 dans les cardiomyoblasts H9c2 ou dans les coeurs transgéniques l'expression de la prokinéticine-2 est augmentée. La surexpression de PKR1 dans les cardiomyocytes augmente la libération son propre ligand la prokinéticine-2 qui agit comme un facteur paracrine, en déclenchant la prolifération/différentiation des cellules progénitrices de l’épicarde (EPDCs) pour induire la néovascularisation. Cette étude offre un nouvel aperçu des stratégies thérapeutiques possibles ayant pour but la restauration de la pluripotence des cellules adultes EPDCs pour promouvoir la neovascularisation en induisant la voie de signalisation de PKR1 dans les cardiomyocytes. Comme PKR1 et PKR2 sont identiques à 85 % et sont exprimés dans les tissus cardiovasculaires, nous avons ensuite déterminé les conséquences pathologiques de la surexpression du récepteur 2 de la prokinéticine (PKR2) dans les cardiomyocytes in vivo. Nous avons généré des souris transgéniques surexprimant PKR2 dans les cardiomyocytes (TG-PKR2) en utilisant le promoteur α-MHC. Nous émettons une hypothèse que PKR2 peut aussi contribuer à la croissance des cardiomyocytes et à la vascularisation. Les coeurs TG-PKR2 ont montré une augmentation de l'expression des gènes de l’hypertrophie et de l'hypertrophie excentrique montrant l'augmentation des diamètres du ventricule gauche et l’augmentation de la longueur des cardiomyocytes. L'analyse morphologique quantitative a montré que les coeurs TG-PKR2 ont une densité des microvaisseaux et un nombre de points de branchement normaux, cependant les coeurs TG-PKR2 ont montré une augmentation des formes et des ultrastructures anormales des cellules endothéliales ce qui indiquent la fenestration des vaisseaux sanguins. L'application de milieu conditionné par les cardioblasts H9c2 surexprimant PKR2 de façon significative induit une diminution de la localisation de jonction serrée ZO-1 dans les cellules endothéliales cardiaques, mimant le modèle TG-PKR2. Ces conclusions fournissent la première évidence génétique que la voie de la signalisation de PKR2 dans les cardiomyocytes cause l'hypertrophie excentrique par régulation autocrine et a diminué l'intégrité des cellules endothéliales par régulation paracrine sans induire l’angiogenèse. Ces souris TG-PKR2 peuvent fournir un nouveau modèle génétique des maladies du coeur. Ensuite nous avons déterminé si PKR2 peut directement induire la fenestration dans les cellules endothéliales cardiaques. Les cellules endothéliales cardiaques surexprimant PKR2 ont montré une augmentation de l'expression de caveolin-1 et une diminution de l'expression de la protéine de jonction serrée ZO-1. De plus, ces cellules ont montré une perturbation de la localisation ZO-1. Ces données indiquent que PKR2 peut induire le dysfonctionnement de la barrière des cellules ayant pour effet directe la fenestration dans les cellules endothéliales cardiaques. Après la stimulation des cellules endothéliales surexprimant PKR2 par la prokinéticine-2, nous avons observé l'internalisation et réduction de la protéin VE-cadhérine. Ces données indiquent la possibilité que la protéine Gα12 couplée avec PKR2 induit un dysfonctionnement de la barrière des cellules endothéliales cardiaques. Pour conclure, pour la première fois nous avons montré que la balance entre l'activation de la voie de signalisation de PKR1 et de PKR2 pouvait être très importante pour protéger les cardiomyocytes des lésions causées par l'ischémie et/ou d’induire la neovascularisation dans le coeur, puisque les rôles des récepteurs de la prokinéticine dans le coeur sont impliqués dans la survie des cellules et l’angiogenèse via PKR1 et dans l'hypertrophie cardiaque et la fenestration via PKR2
Cardiovascular disease remains the number one cause of mortality and is fast becoming the number one health concern worldwide. Identification of new factors responsible for regulation of the cardiovascular system and generation of animal models of cardiovascular disease are important steps to better understand the pathogenesis of the heart failure including congenital heart disease and to develop new therapies. Prokineticins are potent angiogenic factors that bind to two G protein-coupled receptors (PKR1 and PKR2) to initiate their biological effects. First, we hypothesize that prokineticin receptor-1 (PKR1) signaling may contribute to cardiomyocyte survival or repair in myocardial infarction. Since we showed that prokineticin-2 and PKR1 are expressed in adult mouse heart and cardiac cells, we investigated the role of prokineticin-2 and PKR1 on cardiomyocytes function. In cardiomyocytes and H9c2 cells, prokineticin-2 or overexpressing PKR1 activates Akt to protect cardiomyocytes against oxidative stress. We thus, further investigated whether intramyocardial gene transfer of DNA encoding PKR1 may rescue the myocardium against myocardial infarction in mouse model. Transient PKR1 gene transfer after coronary ligation reduces mortality and preserves left ventricular function by promoting neovascularization and protecting cardiomyocytes. Our results suggest that PKR1 may represent a novel therapeutic target to limit myocardial injury following ischemic events. Next, we investigated the pathological consequences of overexpressing PKR1 in cardiomyocytes in vivo. We have generated transgenic mice overexpressing PKR1 in cardiomyocytes (TG-PKR1) using α-MHC promoter. TG-PKR1 hearts displayed no spontaneous abnormalities in cardiomyocytes but showed an increased number of capillary density and arterioles. Moreover, overexpressing PKR1 in H9c2 cardiomyoblasts or in TG-PKR1 hearts upregulated prokineticin-2 expression. Cardiomyocyte-PKR1 signaling upregulates its own ligand prokineticin-2 that acts as a paracrine factor, triggering Epicardial-derived Progenitor cells (EPDCs) proliferation/differentiation to induce neovascularization. This study provides a novel insight for possible therapeutic strategies aiming at restoring pluripotency of adult EPDCs to promote neovasculogenesis by induction of cardiomyocyte PKR1 signaling. Since PKR1 and PKR2 are 85% identical and expressed in cardiovascular tissues, next we investigated the pathological consequences of overexpressing prokineticin receptor-2 (PKR2) in cardiomyocytes in vivo. We have generated transgenic mice overexpressing PKR2 in cardiomyocytes (TG-PKR2) using α-MHC promoter. We hypothesize that PKR2 may also contribute to cardiomyocyte growth and vascularization. TG-PKR2 hearts showed increased hypertrophic gene expression and eccentric hypertrophy which showed that increased left ventricular diameters and increased the length of cardiomyocytes. Quantitative morphological analysis showed that TG-PKR2 hearts have a normal micro vessel density and number of branch points, however TG-PKR2 hearts showed increased abnormal endothelial shape and ultrastucture which indicate the fenestration of blood vessels. Application of media conditioned by H9c2 cardioblast cells overexpressing PKR2 significantly induced impaired ZO-1 tight junction localization in cardiac endothelial cells, mimicking the TG-PKR2 model. These findings provide the first genetic evidence that cardiomyocyte-PKR2 signaling leads to eccentric hypertrophy in an autocrine regulation, and impaired endothelial integrity in a paracrine regulation without inducing angiogenesis. These TG-PKR2 mice may provide a new genetic model for heart disease. Next we investigated whether PKR2 can directly induce fenestration into cardiac endothelial cells. PKR2 overexpressing cardiac endothelial cells showed increased caveolin-1 expression and decreased ZO-1 tight junction protein expression. Moreover, those cells showed disruption of ZO-1 localization. These data indicate PKR2 can induce cell barrier dysfunction resulting in fenestration into cardiac endothelial cells as a direct effect. After prokineticin-2 stimulation in PKR2 overexpressing cardiac endothelial cells, we observed internalization and downregulation of VE-cadherin. These data indicate the possibility of Gα12 coupling with PKR2 to induce cell barrier dysfunction in cardiac endothelial cells. As a conclusion, for the first time we have shown that the balance between the activation of PKR1 and PKR2 signaling could be very important to prevent cardiomyocytes from ischemic insult and/or to induce neovascularization in heart, since the roles of prokineticin receptors in heart are involved in cell survival and angiogenesis via PKR1 and in cardiac hypertrophy and fenestration via PKR2

Abstract:
The natriuretic peptides, atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP) and C-type natriuretic peptide (CNP) are members of a family of hormones that play an important role in mammalian fluid and electrolyte balance. In the periphery, natriuretic peptides reduce blood volume and subsequently blood pressure by increasing renal natriuresis and diuresis and relaxation of vascular smooth muscle. The actions of natriuretic peptides are mediated via two membrane-linked guanylate cyclase receptors (NPR-GC); natriuretic peptide receptor-A (NPR-A) which has a high affinity for ANP and BNP; and natriuretic peptide receptor-B (NPR-B)which has the greatest affinity for CNP. A third receptor not linked to guanylate cyclase, natriuretic peptide receptor-C (NPR-C) also exists, which binds to ANP, BNP and CNP with a relatively equal affinity, and is involved with clearance of the peptides from the circulation and tissues. The natriuretic peptides are present in the brain and are particularly predominant in cardiovascular and fluid and electrolyte regulating areas such as the anteroventral third ventricle (AV3V) region. This distribution has led to the suggestion natriuretic peptides play a neuromodulatory role in the central control of fluid homeostasis. Natriuretic peptides in the brain have been observed to inhibit the release of other fluid and electrolyte regulating hormones such as arginine vasopressin (AVP) and angiotensin II (AII). Natriuretic peptides have also been identified in the non-mammalian vertebrates although information regarding the distribution of the peptides and their receptors in the non-mammalian brain is limited. In amphibians, immunohistochemical studies have shown that natriuretic peptides are highly concentrated in the preoptic region of the brain, an area believed to be analogous to the A\T3\ region in mammals, which suggests that natriuretic peptides may also be involved in central fluid and electrolyte regulation in amphibians. To date, CNP is the only natriuretic peptide that has been isolated and cloned from the lower vertebrate brain, although studies on the distribution of CNP binding sites in the brain have only been performed in one fish species. Studies on the distribution of ANP binding sites in the lower vertebrate brain are similarly limited and have only been performed in one fish and two amphibian species. Moreover, the nature and distribution of the natriuretic peptide receptors has not been characterised. The current study therefore, used several approaches to investigate the distribution of natriuretic peptides and their receptors in the brain of the amphibian Bufo marinus. The topographical relationship of natriuretic peptides and the fluid and electrolyte regulating hormone arginine vasotocin was also investigated, in order to gain a greater understanding of the role of the natriuretic peptide system in the lower vertebrate brain. Immunohistochemical studies showed natriuretic peptides were distributed throughout the brain and were highly concentrated in the preoptic region and interpeduncular nucleus. No natriuretic peptide-like immunoreactivity (NP-IR) was observed in the pituitary gland. Arginine vasotocin-like immunoreactivity (AvT-IR) was confined to distinct regions, particularly in the preoptic/hypothalamic region and pituitary gland. Double labelling studies of NP-JR and AvT-IR showed the peptides are not colocalised in the same neural pathways. The distribution of natriuretic peptide binding sites using the ligands 125I-rat ANP (125I-rANP) and 125I-porcine CNP (125I-pCNP) showed different distributions in the brain of B. marinus. The specificity of binding was determined by displacement with unlabelled rat ANP, porcine CNP and C-ANF, an NPR-C specific ligand. 125I-rANP binding sites were broadly distributed throughout the brain with the highest concentration in pituitary gland, habenular, medial pallium and olfactory region. Minimal 125I-rANP binding was observed in the preoptic region. Residual 125I-rANP binding in the presence of C-ANF was observed in the olfactory region, habenular and pituitary gland indicating the presence of both NPR-GC and NPR-C in these regions. 125I-pCNP binding was limited to the olfactory region, pallium and posterior pituitary gland. All 125I-pCNP binding was displaced by C-ANF which suggests that CNP in the brain of B. marinus binds only to NPR-C. Affinity cross-linking and SDS-PAGB demonstrated two binding sites at 136 kDa and 65 kDa under reducing conditions. Guanylate cyclase assays showed 0.1 µM ANP increased cGMP levels 50% above basal whilst a 10-fold higher concentration of CNP was required to produce the same result. Molecular cloning studies revealed a 669 base pair fragment showing 91% homology with human and rat NPR-A and 89% homology with human, rat and eel NPR-B. A 432 base pair fragment showing 67% homology to the mammalian NPR-C and 58% homology with eel NPR-D was also obtained. The results show natriuretic peptides and their receptors are distributed throughout the brain of B. marinus which indicates that natriuretic peptides may participate in a range of regulatory functions throughout the brain. The potential for natriuretic peptides to regulate the release of the fluid and electrolyte regulating hormone AVT also exists due to the high number of natriuretic peptide binding sites in the posterior pituitary gland. At least two populations of natriuretic peptide receptors are present in the brain of B. marinus, one linked to guanylate cyclase and one resembling the mammalian clearance receptor. Furthermore, autoradiography and guanylate cyclase studies suggest ANP may be the major ligand in the brain of B. marinus, even though CNP is the only natriuretic peptide that has been isolated from the lower vertebrate brain to date.

Abstract:
Structural information for the zebrafish P2X4 receptor in both an agonist bound and unbound resting state provided a major advance in understanding agonist action and has given insight into movement that occurs in the receptor upon ATP binding. Despite agonist action now being well characterised, the molecular basis of antagonism is poorly understood. In this thesis the mechanism of antagonist action at the hP2X1 receptor has been investigated through determining properties of chimeras and mutant receptors based on differences between antagonist sensitive and insensitive P2X receptors. The antagonists suramin, NF449 and PPADS potently inhibit the human P2X1 receptor but have little or no action at the rat P2X4 receptor. The extracellular loop of the hP2X1 receptor was shown to determine antagonist sensitivity and was therefore split into four sections, residues of which were swapped with corresponding residues of the antagonist insensitive rP2X4 receptor and vice versa. Sub-chimeras and point mutations were then made to identify particular residues and regions which contribute to antagonist action. These experiments identified two regions important for NF449 binding at the receptor. These are a cluster of four positively charged residues at the base of the cysteine rich head region (136-140) and three residues located just below them (T216, H224 and Q231). An NF449 bound model of the hP2X1 receptor has been generated. The introduction of the four positively charged residues at the base of the cysteine rich head region to the rP2X4 receptor introduced suramin and PPADS sensitivity to this previously insensitive receptor. This mutation is thought to cause a conformational change which allows the antagonist to bind at residues which are already present in the wildtype receptor. In summary this thesis has advanced the understanding of antagonist action at the hP2X1 receptor and the antagonist insensitivity of the rP2X4 receptor.

Abstract:
There is an expanding family of cyclic nucleotide-gated cation channels (CNGCs) with expression of family members reported in rod and cone photoreceptor cells, olfactory epithelium, heart, kidney, sperm and aorta. Although functions have been assigned to CNGCs in sensory cells, the function of such channels in non-sensory cells is unknown. A PCR-based screen showed that a CNGC is expressed throughout bovine heart tissue and also in bovine aorta, a bovine aorta endothelial cell line and a human umbilical vein endothelial cell line. Sequence data from these amplified products showed that the CNGC expressed in bovine heart and vasculature is highly related to the bovine rod photoreceptor channel. This was also the case for PCR-generated clones spanning the entire coding sequence of the CNGC from porcine coronary artery smooth muscle tissue. Cyclic GMP is an important messenger in vascular smooth muscle relaxation and therefore this CNGC may play a key role in this process. The second messenger pathways which may be involved in the gating of cardiovascular CNGCs have also been studied by attempting to heterologously co-express a cGMP-generating receptor, ANP-RA, with a CNGC in HEK293 cells. The inward rectifier K+ channel subunits Kir 3.1 and Kir 3.4 have been heterologously co-expressed in MEL cells using a mammalian expression vector which incorporates the ?-globin LCR and promoter allowing high levels of gene expression in a 'position independent' manner. Electrophysiological analysis of these co-expressing cell lines shows that Kir 3.1 and Kir 3.4 form a heteromultimeric ion channel complex which displays the features of the native G-protein activated atrial muscarinic K+ channel, KACh, and it is probable that these two inward rectifier channel subunits are major components of KACh.

Abstract:
The central effect of nicotine on cardiovascular regulation has been extensively studied. However, due to its unselective nature for nicotinic acetylcholine receptors (nAChR) the involvement of specific nAChRs at sites in the brain, in central nervous cardiovascular regulation remains unclear. The effects of intracerebroventricular (i.c.v.) and intracisternal (i.e.) injections of the a7 selective agonist, PSAB-OFP, and the a4p2 selective agonist, TC-2559, were investigated on blood pressure (BP), heart rate (HR) and renal sympathetic nerve activity (RSNA) compared with nicotine, in the anaesthetised rats. PSAB-OFP and TC-2559 i.c.v. caused a delayed dose-related increase in BP and RSNA. When given i.e. the action was similar except the rise in BP was more immediate. The possibility that the pressor response was partly due to the agonists causing the release of the vasoconstrictor vasopressin into the circulation was tested by repeating the i.c.v. and i.e. injections of the agonists in the presence of a selective vasopressin Via antagonist. In the presence of Vi antagonist (i.v.), PSAB-OFP and TC-2559 (i.c.v.) now induced no change in BP or RSNA however i.e., the increase in BP and RSNA was delayed with TC-2559, while PSAB-OFP caused a decrease in BP and no change in RSNA. The cardiovascular effects of i.c.v. PSAB-OFP and TC-2559 in the presence of Vi receptor antagonist (i.c.v.) were also completely blocked. PSAB-OFP and TC-2559 (i.e.) in rats pre-treated with Vi antagonist (i.e.), no longer produced an increase in BP and RSNA. However, the delayed fall in BP caused by PSAB-OFP was potentiated. Nicotine i.c.v. caused a dose-related increase in BP and renal sympathoinhibition while i.e. the rise in BP was larger and now associated with a bradycardia. In the presence of Vj antagonist (i.v.), nicotine's (i.c.v.) cardiovascular effects were blocked however nicotine i.e. caused a decrease in BP, RSNA and HR. In the presence of Vi antagonist (i.c.v.), nicotine caused no change in RSNA, but BP still increased. In the presence of Vi antagonist (i.e.), nicotine i.e. induced a decrease in RSNA and HR, with no change in BP. This study indicates that activation of a4p2 and

Abstract:
Glucagon-like peptide-1 is an isulin-like peptide hormone from the incretin family. The most popular pharmaceutical analogue of GLP-1 at the moment is liraglutide. GLP-1 receptors are localized in many areas of the brain responsible for the regulation of metabolic processes and eating behavior and in specific areas of the pancreas, heart, blood vessels, immune system, skin and adipose tissue, gastrointestinal tract and kidneys. We can definitely say that the effect of liraglutide extends to all tissues equipped with GLP-1 receptors, while the effect of the drug on the cardiovascular system, immune system, kidneys and gastrointestinal tract is still being studied. Also interesting is the possible effect of liraglutide on the liver, as an organ directly related to lipid and carbohydrate metabolism. In this article, we analyze the possibilities of using Saxenda, the main active ingredient of which is liraglutide, to potentiate the hepatoprotective effects of the Hepaton-vet drug in groups of rats with induced hepatopathy, evaluating the effect of these drugs on the parameters of a clinical blood test.

Abstract:
O Sistema Cardiovascular é um importante objeto de estudo dos programas de intervenção introduzidos no Brasil com a finalidade de modificar fatores de risco cardiovasculares e diminuir a morbidade e a mortalidade das doenças cardíacas. O perfil dos pacientes interfere diretamente na progressão do tratamento, sendo necessário compreender as características relacionadas a cada paciente. Assim, objetiva-se analisar o perfil das pessoas com doenças cardiovasculares que realizam tratamento farmacológico dessa comorbidade na região Sul do Brasil. O estudo trata-se de um estudo epidemiológico de cunho exploratório descritivo. Os dados foram coletados através de um formulário eletrônico compartilhado por meio das redes sociais Whatsapp, Facebook e Instagram. Além disso, foi usada a aplicação direta dos questionários nas Unidades Básicas de Saúde de Chapecó, Santa Catarina. As questões compreendiam o gênero, faixa etária, ocupação, estado de residência, escolaridade e medicamentos usados. A população do estudo foi composta por cardiopatas em tratamento medicamentoso maiores de 18 anos. Foram obtidas 165 respostas válidas, 66.7% do gênero feminino, 71% são assalariados ou aposentados, 93% residem em Santa Catarina, o ensino fundamental incompleto foi a escolaridade mais observada e a faixa etária predominante foi de pessoas com mais de 60 anos (43%). Entre as comorbidades presentes, a hipertensão arterial sistêmica foi a mais prevalente (88.5%). A classe farmacológica mais utilizada como forma de tratamento foram os medicamentos bloqueadores do receptor da angiotensina (47,9%) e 60.6% dos participantes estão em tratamento há mais de dez anos. Em suma, concluiu-se que o perfil das pessoas com doenças cardiovasculares observado no estudo é composto predominantemente por mulheres, assalariados ou aposentados, e pessoas com mais de 60 anos. Hipertensão arterial sistêmica foi a doença mais prevalente, os medicamentos mais utilizados foram os bloqueadores dos receptores de angiotensina e a maioria das pessoas estão em tratamento há mais de 10 anos.

Abstract:
Review question / Objective: To assess the beneficial effect and safety of finerenone for patients with chronic kidney disease associated with type 2 diabetes. Condition being studied: Chronic kidney disease (CKD) is a major contributor to morbidity and mortality from non-communicable diseases, affecting almost 700 million people worldwide. Approximately 40% of patients with diabetes have CKD, which exposes them to a 3-fold higher risk of cardiovascular death versus those with T2D alone. Strategies to protect the kidneys of patients with CKD and T2D may reduce their risk of cardiovascular events. Finerenone, a nonsteroidal, selective mineralocorticoid receptor antagonist, reduced composite kidney and cardiovascular outcome in trials involving patients with chronic kidney disease. Recently, quite a few clinical studies have been conducted to compare finerenone and placebo. Our meta-analysis aimed to investigate the efficacy and safety of finerenone in chronic kidney disease associated with T2D. 1st author* - Mingzhu Zhang and Wujisiguleng Bao contributed equally to this study.
