Texte intégralCardiomyopathies are cardiac diseases of various causes, among them hypertensive cardiomyopathy and alcoholic cardiomyopathy. Arterial hypertension is one of the main causes of cardiac failure. Chronic alcohol consumption has negative effects in the body: liver, digestive system, neurological system and cardiac system. The cardiac damage caused by these factors (hypertension and alcohol consumption) is regulated by growth factors such as insuline-like growth factor-1 (IGF-1) and myostatin. In case of cardiac damage, the heart has some compensatory mechanisms to revert them. In this thesis the effects of arterial hypertension and chronic alcohol consumption on IGF-1 and myostatin cardiac expression. Cardiac tissue from donors was available (healthy, with hypertension, with alcohol consumption and with other causes of cardiomyopathy). Excessive alcohol consumption in patients without cardiac damage decreases IGF-1 expression. Myocardiac expression of IGF-1 and myostatin was studied for each group of donors. Donors affected by cardiomyopathy (hypertensive or alcoholic) presented an increase on myostatin expression. These results open the door to a therapeutic objective with IGF-1 and myostatin to control the cardiac damage caused by hypertension or alcohol consumption.

Texte intégralThe management and monitoring of classical cardiovascular risk factors such as hypertension, hypercholesterolemia, hyperglycaemia and smoking habit have not been able to modify the main cause of morbidity and mortality in patients with type 1 diabetes mellitus, the coronary artery disease. The importance of this diabetes complication contrasts with the existing controversy about the need for cardiovascular screening among patients with diabetes and subclinical cardiovascular disease, with different opinions about some image tests for the diagnosis of the cardiovascular disease in the preclinical phase and with the lack of knowledge about the real role, in patients with type 1 diabetes mellitus, of certain new cardiovascular risk factors such as vitamin D, different inflammatory markers or liver disease for non-alcoholic fat deposit. In this research we have studied a cohort of patients with type 1 diabetes mellitus from the Mediterranean area of Badalona, asymptomatic from a cardiovascular point of view and with more than 10 years of evolution of their disease, through clinical characterization, analysis of serological parameters of potential relevance such as adiponectin, YKL-40 and 25-hydroxyvitamin D, as well as liver ecographic evaluation for the detection of hepatic non-alcoholic steatosis. All the information extracted has been correlated with early atherosclerotic data obtained by measuring coronary artery calcification by computerized tomography and the measurement of the carotid intima-media thickness through ultrasound. As a result, our cohort, a significant sample of the population with type 1 diabetes mellitus in our area, has a very low prevalence of subclinical cardiovascular disease, approximately 10%. In addition, a good correlation between the results of carotid ultrasound and the quantification of coronary calcium by tomography has been detected, indicating the potential of these tests for the diagnosis of subclinical cardiovascular disease in patients with type 1 diabetes mellitus. The evaluation of the non-classical cardiovascular risk factors regarding the association with the presence of preclinical cardiovascular disease has discarded the concentrations of vitamin D and the serum markers such as adiponectin or YKL-40 but, opposite of that, in the univariate study of the association between the presence of liver steatosis and carotid atherosclerosis, a link was confirmed. It is concluded that, in our territory with recognized low cardiovascular risk, there is a very small prevalence of subclinical cardiovascular disease among patients with type 1 diabetes mellitus, which does not justify generalized screening, but that, in certain patients, we have diagnostic test for its detection. Therefore, in the study of the patient with type 1 diabetes mellitus from the Mediterranean area and, based on the data obtained, we can use the carotid ultrasound for detection and abdominal ultrasound for the stratification of the cardiovascular risk. This deeper understanding of the atherosclerosis of the patient with type 1 diabetes mellitus in our area, in terms of prevalence, diagnostic methods, severity and associated factors, helps us to design preventative, therapeutic and follow-up interventions that are potentially more targeted and effective.
Perna, Barrull David. « Efecte del tractament prenatal amb betametasona en el desenvolupament de la diabetis mellitus tipus 1 ». Doctoral thesis, Universitat Autònoma de Barcelona, 2019. http://hdl.handle.net/10803/670183.
Texte intégralRecientemente la incidencia de diabetes mellitus tipo 1 (DT1) está aumentando en todo el mundo y la causa de este hecho sigue siendo desconocida. Los factores ambientales son cruciales en el desarrollo de la DT1, pero hasta el momento no han sido estudiados exhaustivamente durante la época prenatal. Los dos actores principales de la DT1, el sistema inmunitario y los islotes pancreáticos, se encuentran en desarrollo hasta la última semana antes del nacimiento y pueden ser fácilmente alterados por efecto de algunos fármacos. En este sentido, los glucocorticoides sintéticos tienen potentes efectos antiinflamatorios e inmunosupresores y pueden cruzar la barrera materno-fetal. Esta familia de moléculas interacciona con el receptor de glucocorticoides que se expresa de forma ubicua en todas las células. La betametasona es un glucocorticoide administrado a mujeres con riesgo de parto prematuro para mejorar la salud perinatal del bebé gracias a estimular la maduración de los pulmones fetales. En la actualidad, al mismo tiempo que aumentan los bebés prematuros, también aumenta la utilización de betametasona. La hipótesis de este trabajo es que la betametasona influye en la incidencia de DT1, mediante modificaciones en el desarrollo del sistema inmunitario prenatal y en la célula β. El objetivo principal del estudio es determinar el efecto de la betametasona en la susceptibilidad de desarrollar DT1. Se realizó un estudio de incidencia en el modelo experimental de DT1, el ratón No Obeso Diabético (NOD). La betametasona prenatal redujo la incidencia de DT1 en la descendencia femenina del grupo tratado (22%) respecto a la incidencia del grupo control (75%), correlacionando con una disminución de los linfocitos infiltrantes del islote. Notablemente, la betametasona indujo hipotrofia en el timo y alteraciones en las subpoblaciones del sistema inmunitario en los ratones recién nacidos. El repertorio de familias Vβ del TCR de los linfocitos T se determinó en ratones de 6 semanas de edad y se observó una reducción en la frecuencia de las familias Vβ autoreactivas. Además, provocó un efecto tóxico en los linfocitos no estimulados del ratón. En las células dendríticas, la betametasona indujo un estado de resistencia a la maduración, lo que comportó una reducción tanto en su capacidad de producir citocinas como una disminución de la proliferación autologa de linfocitos T γδ y secreción de IL-17. El efecto de la betametasona en la célula β se determinó en la línea celular NIT-1, en páncreas y en islotes purificados de ratón NOD. La betametasona redujo la viabilidad de las células NIT-1, evitando la proliferación celular y reduciendo la secreción de insulina. También, este fármaco indujo una disminución de la molécula CD44 y un incremento de MHC de clase I en la membrana de las células NIT-1. Por otro lado, la betametasona alteró la expresión génica en la línea celular NIT-1, en el páncreas y en los islotes murinos, afectando genes relacionados con la autoinmunidad, el metabolismo, la masa del islote e inhibidores de la regulación inmunitaria. Para realizar una aproximación al efecto en humanos, se determinó el efecto de la betametasona en leucocitos humanos. Se utilizaron células mononucleares de sangre periférica y observándose únicamente un efecto tóxico en linfocitos B y monocitos. Además, datos epidemiológicos preliminares recogidos de pacientes con DT1 del HUGTiP apuntan hacia el efecto protector de la betametasona en el riesgo de desarrollar DT1. En conclusión, la betametasona protege contra la DT1 experimental a través de alteraciones de la respuesta inmunitaria y reduciendo el reconocimiento autoinmune contra las células β. Estos resultados, junto datos preliminares de estudios en humanos, apoyan el efecto protector de la betametasona prenatal en el desarrollo de la DT1
The incidence of type 1 diabetes (T1D) has been steadily increasing worldwide in the last years and the cause remains to be elucidated. Environmental factors are crucial in the pathogenesis of T1D, but these factors have not been studied thoroughly during the prenatal stage. The two actors in the development of T1D, the immune system and the pancreatic islets, are still developing until the last weeks before delivery and can be easily altered by drugs. In this sense, synthetic glucocorticoids have powerful anti-inflammatory and immunosuppressive effects and can cross the maternofoetal barrier. This family of drugs interacts with the ubiquitously expressed glucocorticoid receptor. Betamethasone is a glucocorticoid administered to women at risk of preterm delivery to improve perinatal outcome after birth by stimulating foetal lung maturation. At the same time that premature new-borns are increasing, the use of betamethasone is raising. The hypothesis of this work is that betamethasone may affect the development of foetal immune system and pancreas, thus influencing the risk of developing T1D in the offspring. The aim of this study was to determine the effect of prenatal betamethasone on T1D susceptibility. An incidence study was performed in the experimental model of T1D, the non-obese diabetic (NOD) mice. Prenatal betamethasone administration caused a reduction in T1D incidence in the female offspring from the treated group (incidence of 22%) when compared to the sham group (incidence of 75%), correlating with a decrease in infiltrating lymphocytes in the islets. Remarkably, betamethasone caused thymus hypotrophy and alterations in immune cells subsets in new-born mice. The TCR Vβ T cell repertoire was assessed in 6 weeks-old mice and a clear decrease in the frequency of autoreactive Vβ families was found. Betamethasone caused in vitro toxicity to resting mouse lymphocytes. In dendritic cells, betamethasone induce a maturation-resistant status, thus decreasing their cytokine production and impairing autologous γδ T lymphocyte proliferation induction ability and secretion of IL-17. The effect of betamethasone on β-cells was determined in the NOD β-cell line NIT-1, in whole pancreas and in purified islets from NOD mice. Betamethasone effects were detrimental for NIT-1 cell viability, arresting cell growth and reducing insulin secretion. Downregulation of CD44 membrane expression and upregulation of MHC class I expression was induced by this glucocorticoid in NIT-1 cells. Betamethasone also altered gene expression in NIT-1 cell line, pancreas and islets, affecting genes related to autoimmunity, metabolism, islet mass and immune checkpoint inhibitors. In order to move forward, human peripheral blood mononuclear cells were used to determine betamethasone effects. A toxic effect was observed only in monocytes and B cells. Moreover, preliminary epidemiological data from paediatric patients with T1D from the Germans Trias i Pujol Hospital reinforces the putative the protective effect of betamethasone in the risk of developing T1D. In conclusion, betamethasone has a protective effect against experimental T1D by altering the immune system response and potentially decreasing autoimmune recognition of β-cells. These results, together with our preliminary data from human studies, support a protective effect of prenatal betamethasone in T1D development.

Texte intégralDiversos estudis de lligament apunten a que a la regió cromosòmica 6p hi podria haver un gen o gens de susceptibilitat per l'esquizofrènia. El nostre grup va escollir un gen d'aquesta regió, el gen que codifica pel Receptor Domini Discoidina 1 (DDR1), com a candidat per l'esquizofrènia. Se sap que DDR1 és un receptor tirosina quinasa que s'expressa de forma molt important en zones proliferatives durant el neurodesenvolupament del cervell de rata i ratolí i també s'ha vist que s'expressa en cervell humà. DDR1 té com lligant el col·lagen, el qual promou la diferenciació i proliferació de les cèl·lules neuroepitelials en rates. El nostre grup ha observat una important expressió de DDR1 en la substància blanca i en concret en els oligodendròcits durant el desenvolupament pre i postnatal en ratolins. A demés l'expressió d'aquest receptor segueix un patró espacio-temporal al procés de mielinització.
En la present tesi doctoral hem estudiat per primera vegada en detall el patró d'expressió gènica i proteïca del receptor DDR1 en cervell humà mitjançant tècniques específiques d'hibridació in situ, immunohistoquímica i de quantificació d'RNAm. Hem trobat que existeix una associació positiva tan a nivell gènic com haplotípic de DDR1 amb l'esquizofrènia mitjançant un estudi d'anàlisi de variants tipus SNPs en una mostra de casos i control.
També hem descrit per primera vegada que DDR1 és una proteïna de la mielina en cervell humà i que entre les 5 diferents isoformes que es coneixen només les isoformes DDR1c i DDR1a es relacionen amb la mielina. D'aquesta tesi es deriven les següents aportacions científiques:

Schizophrenia is one of the most common psychoses in the world today. It has a prevalence of 1% in the population and is of unknown etiology. One of the most widely accepted etiopathogenic hypotheses for schizophrenia is neurodevelopmental theory, which postulates that schizophrenia originates from a variety of neurogenetic and gliogenetic disorders during perinatal development. Many studies have reported that schizophrenic patients have alterations in their myelin (white matter of the brain). Axons must be myelinated if signals are to be properly transmitted between neurons. The cells that form the myelin sheaths of the axons in the CNS are the oligodendrocytes.
In humans, the myelination process peaks in the perinatal, childhood and adolescence stages. It is during this last stage that the symptoms of schizophrenia become manifest. Several linkage studies indicate that the 6p chromosomal region may contain one or more susceptibility genes for schizophrenia. Our group chose a gene in this region, the gene encoding the discoidin domain receptor 1 (DDR1), as a candidate gene for schizophrenia.
DDR1 is known to be a receptor tyrosine kinase which is highly expressed in proliferative areas during murine brain development, and has also been shown to be expressed in human brain. The DDR1 ligand is collagen, which promotes the proliferation and differentiation of the neurophitelial cells in rats. Our group has observed that DDR1 is significantly expressed in the white matter and particularly in oligodendrocytes during pre- and postnatal development in mice. Furthermore, the expression of this receptor follows a spatial-temporal pattern similar to the process of myelination.
In this doctoral thesis we have made the first detailed study of the pattern of gene and protein expression of DDR1 in human brain, using specific techniques such as in situ hybridization, immunohistochemistry and quantification of RNAm. We found a positive association of DDR1 with schizophrenia in a case-control association study using markers of the SNP (single nucleotide polymorphism) type.
We have also reported for the first time that DDR1 is a myelin protein in the human brain and that of the five different isoforms that are known only isoforms DDR1c and DDR1a are related to the myelin.

Texte intégralThe role of the hepatitis C virus (HCV) NS3/4A protease in ablating the signaling pathway involved in the production of alpha/beta interferon (IFN-‐α/β) suggests a relationship between NS3/4A proteolytic activity and a patient’s response to IFN-‐ based therapy. To identify viral factors associated with the HCV treatment response, we analyzed the pretreatment NS3/4A protease gene quasispecies composition of 56 HCV genotype 1–HIV-‐1-‐coinfected patients treated in our clinic with pegylated IFN (pegIFN) plus ribavirin (RBV). The catalytic efficiency of the dominant (i.e., the most abundant) quasispecies was also assayed for Cardif cleavage and correlated with treatment outcome. A total of 1,745 clones were isolated and sequenced. Significantly less nucleotide quasispecies heterogeneity and lower Shannon entropy values were detected within the responder group (P < 0.05). A correlation was also found between the efficiency of NS3/4A protease Cardif cleavage and therapy outcome. Proteases from sustained responder patients were more efficient at processing Cardif (mean standard error of the mean [SEM], 0.8960 ± 0.05568; n = 19) than proteases from nonresponders (mean ± SEM, 0.7269 ± 0.05306; n = 37; P < 0.05). Finally, the amino acid p distance (the proportion [p] of nucleotide sites at which two sequences being compared are different) was significantly shorter in patients with an interleukin-‐28B (IL-‐28B) risk allele (P < 0.01), suggesting that IL-‐28B risk allele carriers exert a lower positive selection pressure on the NS3/4A protease. NS3/4A protease efficiency in cleaving Cardif may be associated with the pegIFN-‐RBV treatment response, as shown in our cohort of HIV-‐HCVcoinfected patients. Greater NS3/4A nucleotide heterogeneity and higher Shannon entropy values in nonresponders suggest that less HCV quasispecies complexity may favor a better response to pegIFN-‐RBV.

Texte intégralType 1 diabetes mellitus (T1D) is the consequence of the autoimmune destruction of pancreatic beta cells of the islets of Langerhans. T1D patients show an increased prevalence of other associated organ-specific autoimmune diseases. Type A chronic atrophic gastritis (CAG) is an autoimmune disease that involves the fundus and body of the stomach and spares the antrum. In the later stage of the disease, pernicious anaemia may result from cobalamin deficiency. The papers published in this thesis have focused on assessing the usefulness of several hormonal and immunological parameters for the study of autoimmune gastritis in patients with T1D. The parameters evaluated were: serum pepsinogen I concentrations (a peptide secreted by zymogenic cells in the body and fundus of the stomach), gastric parietal cell antibodies, serum cobalamin or vitamin B12 concentrations, plasma ghrelin concentrations (a 28-aminoacid peptide mainly synthesised in the neuroendocrine cells of the stomach) and finally, the analysis of regulatory T cells (Tregs), which are a subset of T lymphocytes involved in controlling autoimmunity. The results of the studies have shown that: 1.- The determination of serum pepsinogen I concentrations together with gastric parietal cell antibodies are the best biochemical marker for the screening of autoimmune gastritis in patients with T1D. The determination of both parameters is more useful than each other separately, for the identification of those patients with a higher risk to present cobalamin deficiency, that in case to be confirmed, should be treated given its possible associated neuropathy. 2.- Plasma ghrelin concentration is not a good biochemical marker of gastric mucosa atrophy in T1D patients with type A CAG. 3.- Plasma ghrelin concentration doesn`t predict neuroendocrine cell hyperplasia in those patients with T1D and type A CAG. 4.- Type 1 diabetic patients with chronic autoimmune gastritis (type A) have a higher frequency of Tregs in peripheral blood compared to T1D patients with no evidence of type A CAG or other associated autoantibodies, and healthy controls. 5.- The number of Tregs in gastric mucosa of T1D patients with type A-CAG is lower than in those with Helicobacter pylori-induced CAG, although higher than that observed in normal gastric mucosa. This fact, underlies the influence of the percentage of Tregs in situ necessary for controlling the chronification of an autoimmune or infectious gastritis.

Texte intégralMagnetotactic bacteria synthesise specialised organelles called magnetosomes. They are composed of a magnetic crystal surrounded by a lipid bilayer and specific proteins. Arranged in chains, they orient magnetotactic bacteria in the geomagnetic field, thereby simplifying their search for their microaerophilic environments. In each sequenced magnetotactic strain, the magnetotaxis genomic island contains the genes involved in magnetosomes formation. Our annotation of the newly sequenced genome of the magnetotactic strain QH-2 shows that the region coding the magnetotaxis genes is not a genomic island, though it has been acquired by lateral genes transfer. In the genome of M. magneticum AMB-1 we identified a new, small genomic island we termed the magnetotaxis islet, encoding 7 genes homologous to genes related to the magnetosomes synthesis. To assess the question of the biological function of this genomic islet, we further investigated the role of one of the seven genes, mamK-like. Filaments were observed in E. coli cells expressing MamK-like-Venus fusion by fluorescence microscopy. In vitro polymerization of both isoforms is comparable, though some differences are present at the structural level. In addition, we demonstrate that mamK-like is transcribed in AMB-1 wild-type and ΔmamK mutant cells. Immunolabelling assay using an anti-MamK antibody reveals the presence of a filament in the ΔmamK mutant. We hypothesise that this filament is due to MamK-like and that it helps maintaining a chain-like organisation of magnetosomes in the mutant strain

Texte intégralLa infección por el virus de la inmunodeficiencia humana (VIH) constituye una de las epidemias más importantes actualmente. El VIH se caracteriza por su elevada variabilidad genética a lo largo de su historia natural. Las múltiples variantes existentes dentro del mismo huésped, lo que se conoce como cuasiespecie, constituyen una fuente de adaptabilidad del virus, pues permiten la disponibilidad de una variante de escape frente una posible presión selectiva en el ambiente (respuesta inmune, fármacos antiretrovirales, etc). A pesar de los grandes avances en el desarrollo de tratamientos eficaces, actualmente no ha sido posible la erradicación de la infección. El tratamiento antirretroviral de gran actividad (TARGA) ha disminuido significativamente la morbi-mortalidad asociada a la infección por el VIH, no obstante, no consigue la eliminación del virus. Consecuencia directa de ello es que, al suspenderlo, el virus reaparece en sangre periférica, siendo necesario mantener el tratamiento de por vida, con sus costes tanto a nivel de efectos secundarios como económicos. Frente esta situación, ha sido necesario el diseño de terapias alternativas como las terapias inmunomediadas (interrupciones estructuradas del tratamiento o vacunas terapéuticas), enfocadas a estimular el sistema inmunológico del paciente para poder suspender el TARGA de forma definitiva o, al menos, durante períodos variables de tiempo. Hoy en día no se conocen con exactitud los efectos que pueda tener la variabilidad del VIH en las terapias inmunomediadas, y el interés de nuestro estudio parte de esta premisa. Por ello, el objetivo de esta tesis es analizar, por primera vez, la evolución del virus en pacientes sometidos a vacunación terapéutica (en nuestro caso, una vacuna terapéutica de células dendríticas pulsadas con el virus autólogo inactivado por calor).
Human Immunodeficiency Virus (HIV) infection is one of the largest epidemics today. HIV is characterized by high genetic variability throughout its natural history. Multiple variants exist within the same host, which is known as quasispecies. These quasispecies are a source of adaptability of the virus, and allow the availability of alternative escape variants against a possible selective pressure in the environment (immune response, antiretroviral drugs, etc). Despite the great advances in the development of effective treatments, now has not been possible to eradicate the infection. Antiretroviral therapy (HAART) has significantly decreased morbidity and mortality associated with HIV infection, however, it fails to eliminate the virus. Direct consequence is that, when HAART is stopped, virus rebound in peripheral blood, being necessary to maintain treatment for life, with its costs both in terms of side effects and economic burden. Facing this situation, it has been necessary to design alternative therapies such as immune-mediated therapies (structured treatment interruptions or therapeutic vaccines), aimed to stimulate the patient's immune system to permanently remove HAART or, at least, for varying periods of time. Today, effects of the variability of HIV in immune-mediated therapies are not exactly known , and the interest of our study is based on this premise. Therefore, the objective of this thesis is to analyze, for the first time, the evolution of HIV in patients undergoing therapeutic vaccination (in our case, a therapeutic vaccine based on dendritic cells pulsed with autologous heat-inactivated virus).
