Métabolisme du cholestérol et function β-cellulaire

Abstract: L'incidence du diabète de type 2 (DT2) atteint des proportions épidémiques ces dernières années en raison du vieillissement de la population et du développement de l'obésité, elle-même secondaire à l'augmentation de la sédentarité et à une alimentation trop riche en graisses. L'insulinorésistance est un événement précoce dans la physiopathologie du DT2, mais qui demeure relativement stable au cours de l'évolution de la maladie. À l'inverse, la capacité insulinosécrétrice de la cellule  pancréatique diminue au… Show more

“…35,36 In the case of specific Abca1 inactivation in β-cells, cholesterol homeostasis is altered, and glucose tolerance is markedly impaired due to defective insulin secretion. 35 This is tied to the PI3K (phosphoinositide 3-kinase)/AKT or PI3K/PKCζ pathways that play an important role in regulating insulin secretion and insulin-stimulated glucose transport, [37][38][39] as well as in promoting the translation of GLUT4 (glucose transporter 4). 40,41 Reducing the level of ABCA1 can disturb both the cholesterol metabolism and the glucose uptake in adult skeletal muscle fibers of high-fat diet-fed mice.…”
