Does high fat diet impair the function of glucagon-like peptide-1 producing L-cells?
Mice fed on HFD exhibited reduced expression in L-cells of many L-cell specific genes, suggesting an impairment of enteroendocrine cell function. Our results suggest that a western style diet may detrimentally affect the secretion of gut hormones and normal post-prandial signaling, which could impact on insulin secretion and satiety.
Natalizumab treatment reduces plasma Osteopontin levels and improves cognition and fatigue in RRMS patients. The results suggest that the improvement of cognitive functions is associated to a decrease of plasma Osteopontin levels.
