Full textDepression and cardiovascular diseases are related but the physiopathology of this association is unclear. Heart rate variability (HRV) and endothelial dysfunction (ED) could account for this association but their involvement remains controversial and only some symptoms of depression, anhedonia and emotional hyporeactivity (EH), seem to be involved. In addition, some methodological obstacles have so far limited the assessment of cardiac and cerebrovascular reactivity in anhedonia and EH. In this work, we establish using two distinct protocols 1) that cerebrovascular changes in depression can be assessed using a new ultrasound technique (Tissue Pulsatility Imaging - TPI) and 2) that HRV and emotional anticipation, as a key process in EH, are associated. Our results suggest that anhedonia and EH in depression can be characterized by a blunted emotional anticipation which is associated with a decreased HRV and a cerebral ED

Full textAlthough an increasing number of clinical studies highlight a strong association of depression and addiction, the mechanisms underlying this co-occurrence are not well understood. The goal of our study is to shed light on the neurobiological mechanisms by which depression-like states enhance addictive behaviors. For this purpose, we employed a genetic model of depression, the Helpless mice (H/Rouen). These mice have been selected on their immobility behavior in the Tail Suspension Test, more prolonged than the Non Helpless mice (NH/Rouen) and the Intermediate mice (I/Rouen) which display an intermediate phenotype We first further characterized their phenotype regarding anxiety and demonstrated that H/Rouen mice displayed exacerbated anxiety-like behavior in a battery of classical behavioral paradigms in contrast to other mouse lines. We next tested the influence of this mixed anxiety- and depression-like phenotype on cocaine vulnerability. We demonstrated that H/ and I/Rouen mice were less sensitive to acute cocaine psychomotor stimulant effects compared to NH/Rouen mice; however, all mouse lines displayed a similar behavioral sensitization to cocaine, indicating that neuroadaptations induced by repeated exposure to this drug shade off initial reactivity differences. exhibited a stronger and durable cocaine-induced conditioned place preference (CPP) compared to I/ and NH/Rouen mice, indicating a higher sensitivity to cocaine-associated cues. This observation led us to explore the neural substrates mediating the increased sensitivity to cocaine reinforcing effects observed in female H/Rouen mice. Our neuroanatomical study, based on Fos expression during the cocaine-induced CPP, highlighted a higher activation of the cingulate prefrontal cortex, the nucleus accumbens shell, the basolateral amygdala and the ventral subiculum in female H/Rouen mice, compared to female I/ and NH/Rouen mice, that may reflect their higher propensity to conditioned drug-seeking. Finally, as the Brain-Derived Neurotrophic Factor within the nucleus accumbens could be implicated in depression as well as in drug vulnerability, we started to assess its expression by western blotting in all the mouse lines, in basal conditions et after conditioning to cocaine

Full textCortical Spreading Depression is a wave of neuronal depolarization that spread slowly across cerebral cortex. It generates a rapid phase of neuronal hyperactivity, followed by a slower phase of electrical silence of cortical cells. It is possible to experimentally induce CSD on several animal models, in vivo or on neocortical slices, by focal application of Glutamate, Acetylcholine or highly concentrated KCl solution, or by electrical stimulation.CSD is widely studied as the pathophysiological mechanism of migraine with aura, but also ischemia. Studies of experimental CSD have shown involvement of numerous biological substances in the wave generation and propagation, including Potassium, Calcium, Glutamate, and other neurotransmitters. The pharmacological approach allows to identify actors of this electrical phenomenon: voltage gated channel, ionotropic glutamate receptors (NMDA & AMPRA-kainate), astrocytes and Na-K pumps.Familial Hemiplegic Migraine is a monogenic form of migraine with aura; the migraine attack is associated with variable motor disorders. Genetic mutations have been described leading to molecular dysfunctions. Nowadays three main forms of this pathology caused by three mutated genes, have been described and studied. FHM type 1 (Cav2.1 gain of function) and FH% type 2 (NaK ATPase pump loss of function) mouse models studies confirmed the important involvement of Glutamate and Potassium in CSD initiation.Type 3 of FHM is caused by Nav1.1 mutations, a voltage gated sodium channel that is widely expressed in GABAergic neurons in which they are essential for excitability. Our team showed on transfected neurons in culture that he mutation is a gain of function, leading to an increased neuronal excitability. However, the link between the mutation, cortical hyperexcitability and CSD facilitation or FHM phenotype, remains unknown.Our work hypothesis and the base of my research project, is that the increasing Nav1.1 channel or GABAergic neurons’ activity, triggers a cortical hyperexcitability and CSD. To confirm this hypothesis, my work required a ex vivo experimental approach, on acute neocortical slices of wild-type and transgenic mice, associated with extracellular electrophysiology, IOS imaging, pharmacology and/or optogenetics. Nav1.1 channel activation by a selective activator (spider toxin), or GABAergic neurons stimulation by optogenetics, can trigger CSD, validating our initial hypothesis and identify a new model of CSD.My work allow us to highlight and characterised a new model of CSD by GABAergic neuron hyperexcitability leading to an initial build up of extracellular potassium, that depolarizes and activates more and more excitatory neurons. This leads to a sustained potassium release until a critical threshold of CSD triggering.In a second time, my thesis work explored a pharmacologic modulation of network excitability, to find new elements that could decrease the CSD susceptibility. To do so, with the same experimental approach, I used a cholinergic agonist, Carbachol, known for modulation the network activity. The results showed that even if Carbachol increases network excitability, it inhibits CSD induction, likely through the muscarinic pathway.In conclusion, during my thesis I identified a new mechanism of CSD induction, and a une inhibitory pathway of CSD by cholinergic modulation

Full textIt is the commonly accepted that a wide variability exists in susceptibility to drug of abuse, both in human and non-human animals. Some personality trait and pathological behaviours are frequently associated with drug addiction. For example, novelty seeking is often observed in drug abuser, and anxious and depressive individuals also frequently abuse drugs. The purpose of this investigation was to examine the respective influence of these factors on the vulnerability to drug addiction. In the first phase, we compared the influence of responses to both forced and free-choice novelty within a population of Wistar rats. The reactivity to forced novelty was associated with a higher sensitivity to the rewarding effects of a low dose of amphetamine and with a lower oral consumption of amphetamine, morphine and sucrose. . In the second phase, we compared the influences of anxiety and helplessness on vulnerability to drug of abuse. In Wistar rats, anxiety was associated with greater conditioned place preference induced by high, but not low, doses of cocaine and amphetamine. In addition, anxiety was not associated with a greater consumption of a low concentration of amphetamine solutions, but anxious animals consumed less of a higher concentration of amphetamine solution than non-anxious animals Similar to anxiety, helplessness was not associated to any difference in drug sensitivity Taken together these results suggest that responses to novelty, anxiety and helplessness are associated with different aspects of vulnerability to drugs of abuse

Full textMajor depressive disorder (MDD) is a chronic and debilitating disease, often worsened by the presence of comorbidities such as chronic pain. There is an urgent need to uncover the mechanisms underlying MDD. Recent work suggests a crucial role of the anterior cingulate cortex (ACC) and basolateral amygdala (BLA) in this disorder. Using optogenetics and a battery of behavioral testings, we highlighted the crucial role of the BLA-ACC pathway in the establishment of depressive-type behaviors. Indeed, the activation of this pathway induces depressive-like behaviors in naïve animals while its inhibition alleviates the depression induced by chronic neuropathic pain. At the molecular level, we have shown that depression induced by stimulation of the BLA-ACC pathway recapitulate similar transcriptomic alterations to those observed in depressed patients. Thus this project brings an extensive behavioral and molecular characterization of the role of the BLA-ACC pathway in emotional processing
Zayed, Abdallah. "The role of chromatin remodelers in dopaminoceptive neurons." Thesis, Sorbonne université, 2019. http://www.theses.fr/2019SORUS437.
Full textGlucocorticoid (GC) hormone release is a key physiological response to stress exposure enabling the organism to cope with environmental challenges. Beneficial when working, a dysfunction of this adaptive response is associated to multiples pathologies including psychiatric disorders. GC act through the binding to their receptor, glucocorticoid receptor (GR). It has been shown that GR gene inactivation in dopaminoceptive neurons (GRD1Cre mice) reduces dopamine neurons activity, decreases responses to cocaine and blocks social aversion induced by repeated social defeat. GR can control genes expression through different mechanisms. Among others, it can interact with SWI/SNF chromatin remodeling complexes either Brahma (Brm) or Brahma-related gene 1 (Brg1) as an ATP catalytic core subunit, which can move the DNA along the nucleosomes thereby opening the chromatin and favoring gene transcription. We found that both Brg1D1Cre and Brm-/- mice showed a complete resilience to repeated social defeat. Moreover, both Brg1D1Cre and Brm-/- mice showed decreased responses to cocaine in behavioral sensitization. Brg1D1Cre mice on the contrary to GRD1Cre showed a normal increase of dopamine neuron firing after social defeat despite their behavioral resilience. We therefore examined cell-signaling and immediate early genes induction in the mutated brain areas of our models and showed that while ERK signaling pathway is normally induced by an acute defeat, the induction of c-Fos and Egr1 genes expression are reduced in the dorsal striatum and the NAc. Altogether, these results lead to further evidences for an involvement of chromatin remodelers in stress-related behaviors
