Scientific summary

 Over the last years, my group is being  studying the neuropeptidergic control of secretions and absorption of nutriments and their contribution to mechanisms regulating energy homeostasis. One interest is in developing a better understanding of the physiological contribution of  meal-generated gastrointestinal signals including gut leptin to the development of obesity and its relation to colon carcinogenesis. Transgenic mice deleted with epithelial cell leptin receptors in the intestine were used. A second interest to better understand the mechanisms  by which gastro-intestinal epithelial cells adapt during over-nutrition and malnutrition conditions. This consists in dissecting the mechanisms involved in modifications of expression/ activity of gut endocrine cells, of key transcription factors reprogramming absorptive capacity of the enterocytes and controlling the renewal (proliferation/differentiation) of gut epithelial cells. A better understanding of the mechanisms driving these adaptations are essential for the development of novel and innovative therapies for the treatment of pathologies such obesity.
