Multivesicular body function

WebEVs have specialized functions in physiological processes, from coagulation and waste management to intercellular communication. Exosomes are formed through the inward budding of a late endosome, also known as a multivesicular body (MVB). The intraluminal vesicles (ILVs) of the multivesicular body (MVB) bud inward into the endosomal lumen. WebMultivesicular bodies (MVB) are endosomal compartments that sort ubiquitinated membrane proteins by incorporating them into vesicles.
