Pulsatile insulin secretion, impaired glucose tolerance and type 2 diabetes

LS Satin, PC Butler, J Ha, AS Sherman - Molecular aspects of medicine, 2015 - Elsevier
Abstract Type 2 diabetes (T2DM) results when increases in beta cell function and/or mass
cannot compensate for rising insulin resistance. Numerous studies have documented the …

Insulin granule biogenesis and exocytosis

M Omar-Hmeadi, O Idevall-Hagren - Cellular and Molecular Life Sciences, 2021 - Springer
