Comparison of localization and release of multivesicular bodies and secretory granules in islet cells: Dysregulation during type-2 diabetes.

Multivesicular bodies (MVBs) are vesicles of endosomal origin containing intraluminal vesicles, which upon fusion with plasma membrane, secrete exosomes. They play a significant role in the physiology and pathology of type-2 diabetes (T2D) due to disrupted intercellular communication. The role of MVBs and their influence on insulin secretory granules (ISGs) of β-cells or their characterization is yet to be uncovered.
