Texto completo da fonteMetformin, an antidiabetic compound, still remains a first-line treatment for type 2 diabetes. The mechanisms by which this compound exerts its antihyperglycemic effect are increasingly documented. However, its anorectic action and central targets remain less studied. Furthermore, increasing data in the literature suggest that physical activity, commonly associated with anti-obesity and anti-diabetic therapies, may increase neural networks’ sensitivity to endogenous signals involved in food intake and body weight control. This suggests that the efficacy of therapies inducing expression modulation of these signals may be directly enhanced by physical activity. In the present study, we sought i) to explore the central effects of metformin in mice and, ii) determine whether physical activity could potentiate the effects of metformin. All my work, in partnership with the company BIOMEOSTASIS brought new elements about mechanisms involved in the central effects of metformin and identified nesfatin-1 as a potential actor for the anorectic effects of this compound

Texto completo da fonteThe central control of energy balance involves a highly regulated neuronal network within the hypothalamus and the dorsal vagal complex (DVC). In these structures, pro-opiomelanocortin (POMC) neurons are known to reduce meal size and to increase energy expenditure. Thus, leptin, a peripheral signal that relays information regarding body fat content, modulates the activity of POMC neurons. MicroRNAs (miRNAs) are short non-coding RNAs of 22-26 nucleotides that post-transcriptionally interfere with target gene expression by binding to their mRNAs. To date, the role of the miRNAs in the control of energy balance remains to be clarified. In this context, we developed a transgenic mouse model with a deletion of the miRNA processing enzyme DICER specifically in POMC cells. Conditional deletion of Dicer in POMC cells leads to an increase in hypothalamic leptin sensitivity. These results suggest an important role of miRNAs in the leptin-dependent POMC neuron activity. Next, we identified and characterized the miRNAs that potentially target POMC mRNA. After the selection of miRNA of interest by in silico approach, we observed that miR-383, miR-384-3p, and miR-488 expressions were up-regulated in the hypothalamus of leptin deficient ob/ob mice. In accordance with these observations, we showed that miR-383, miR-384-3p and miR-488 were also increased in db/db mice that exhibit a non-functional leptin receptor. The intraperitoneal injection of leptin down-regulated the expression of these miRNAs of interest in the hypothalamus of ob/ob mice, thus showing the involvement of leptin in the expression of miR-383, miR-384-3p and miR-488

Texto completo da fonteThe long term maintenance of body weight results from a balance between energy expenditure and intake. This balance, called “energy homeostasis”, involves a large number of molecules. Among these, nesfatin-1, discovered in 2006, is an 82 amino-acid peptide derived from the cleavage of the protein NUCB2. The interest generated by nesfatin-1 lies in its anorexigenic effect performed independently of leptin signalization. Nesfatin-1 is expressed in several organs such as adipose tissue, stomach, pancreas, and brain. In the brain, its expression is limited to a few neuronal groups located in the hypothalamus and dorsal vagal complex. In this work, we analyzed the sensitivity of NUCB2/nesfatin-1-expressing neurons to physiological and physiopathological peripheral signals affecting food intake. We show that these neurons are sensitive to hypoglycemia and that they could contribute to the counter-regulatory response established in order to restore the basal blood glucose level. Moreover, we show that they are activated in response to two inflammatory stimuli: lipopolysaccharide administration and food intoxication with a mycotoxin named deoxynivalenol. So, NUCB2/nesfatin-1-expressing neurons could contribute to the development of inflammatory anorexia. This study was the first evidence of an involvement of this peptide in a pathological situation. Taken together, these results suggest that in addition to its satiating effect, nesfatin-1 participates in the central signalization involved in glucodetection and inflammatory responses
Dupin, Alice. "Insular Cortex neurons projecting to the vagal complex : characterization and roles in behavior and inflammation". Electronic Thesis or Diss., Sorbonne université, 2024. http://www.theses.fr/2024SORUS192.
Texto completo da fonteBrain-body interactions are crucial for organisms survival; the brain constantly receives external and internal information that it integrates to regulate various physiological function. Notably, the nervous system closely interacts with the immune system. In the case of inflammation, the brain's features enable an optimized regulation of immune responses. These features include the brain's ability to sense environmental cues, anticipate outcomes, and transmit signals rapidly through an extensive network of neurons innervating the entire body within milliseconds. The vagus nerve, linking the brain to visceral organs, is an important support of this bidirectional communication. It is composed of sensory and motor branches. Sensory afferences carry peripheral information to the vagal complex in the brain which transmits the signals to deeper brain structures, while motor efferences mediate the generated responses to targeted organs.In processing internal information, the insular cortex emerges as a critical multimodal hub. As a sensory cortex, it receives various inputs from external-sensing systems such as somatosensory, and olfactory cortices, while also being densely interconnected with regions processing internal cues such as inflammatory threats, such as the vagal complex. This allows the insular cortex to integrate exteroceptive and interoceptive information and play a pivotal role in the salience network. Within the organism, it can optimize responses to specific situations by regulating cardiac or intestinal activity, as well as immune responses, but the underlying circuits are poorly understood. Given the role played by the vagus nerve in transmitting information between the brain and the periphery, along with the presence of projections from the insular cortex to the vagal complex (InsCtxVC), we hypothesize that some of the insular cortex functions are mediated through the vagus nerve.To investigate the role of InsCtxVC, we first characterized these neurons anatomically using viral retrograde labeling. We found that InsCtxVC are predominantly located within the posterior-intermerdiate InsCtx, mainly in layer V, and express CTIP, a downstream effector of the Fezf2 pathway. Next, we examined the connectivity of these neurons using viral labeling of outputs and inputs. Our experiments revealed that within the vagal complex, InsCtxVC neurons preferentially synapse with the medial NTS (rather than caudal NTS or DMN), and the central amygdala and parasubthalamic nucleus. Additionally, we analyzed their presynaptic inputs, highlighting a predominant innervation from sensory cortices including the insula itself, the somatosensory and olfactory cortices. Based on our anatomical findings and existing litterature, we screened various contexts likely to recruit the InsCtxVC. Through specific chemogenetic and optogenetic manipulation of these neurons, we found that InsCtxVC are not involved in anxiety behaviors or neuroimmune conditionned taste aversion. However, chemogenetic activation of InsCtxVC neurons during early LPS-induced inflammation exacerbates sickness behavior, including increased weight loss, elevated blood proinflammatory cytokines and corticosterone response. Taken together, our results characterize a previsouly undefined neuronal population linking the insular cortex to a major parasympathetic center, which regulates immune responses in the periphery

Texto completo da fonteBDNF has been implicated as an anorexigenic factor in the central regulation of food intake. In the present work, we identify the DVC as a key site where BDNF plays its anorexigenic role, downstream of melanocortinergic signalling. In the adult rat, we show that central application of exogenous BDNF at the DVC level induces anorexia and body weight loss, whereas endogenous BDNF protein content in the DVC is modulated in a manner consistent with an anorexigenic role, during the dark/light cycle, as well as following experimental paradigms affecting nutritional status or implying leptin, CCK or ghrelin treatments. In addition, we show that 4th ventricle administration of agonists or antagonists for type 3/4 melanocortinergic receptors (MC3/4R) induces respectively an increase and a decrease in BDNF protein content, whereas the orexigenic effects of the MC3/4R antagonist are blocked by a co-treatment with exogenous BDNF

Texto completo da fonteThe dorsal vagal complex (DVC) is a neurovegetative cerebral center displaying plasticity and neurogenesis in adult rat. In vivo, I have demonstrated occurrence of proliferative cells within DVC by Ki-67 immunohistochemistry and by D-cyclin western-blot. In vitro, in primary cultures from microdissected DVC, I have generated neurospheres showing self-renewal and containing neuronal and glial cells. Therefore adult rat DVC does contain neural stem cells. I have looked for extracellular regulators of DVC stem cells through two approaches. In vivo, lesion-induced proliferative stimulation in DVC was correlated, by RT-PCR and by DNA microarray, with transcriptional induction of two mitogens: the growth factors EGF and BDNF. In vitro, neural stem cell proliferation was inhibited by the anorexigenic hormone leptin. These cellular neurobiology data bring about novel vistas about integrative processes in autonomic neurosciences

Texto completo da fonteImmobilization stress (IS) elicits feeding inhibition. Food intake is regulated by the dorsal vagal complex (DVC) and the hypothalamus. The DVC emerged as a novel focus of adult neurogenesis, the role of which is unknown. I have investigated the effect of chronic IS (3 weeks) on DVC neurogenesis by means of in vivo BrdU incorporation in brain, by using double immunohistochemistry and confocal microscopy. I have shown that IS inhibits adult neurogenesis by 40% in DVC and stimulates it by 200% in olfactory bulb. It suggests that DVC neurogenesis plays a specific role in long-term food intake regulation. I have then characterized the effect of IS on expression of the key messengers regulating food intake in DVC and hypothalamus, by means of ELISA or RT-PCR on tissular extracts. NPY, AgRP, CART, POMC are significantly induced by acute IS. These results contribute to neurobiology of nutrition and of DVC
