This research aims to explore how autophagy affects the fusion of multivesicular bodies with autophagic vacuoles in K562 cells.
Analyzed K562 cells overexpressing GFP-Rab11 and red fluorescent protein-LC3 using confocal microscopy
Induced autophagy through starvation or rapamycin
Examined the role of calcium in the fusion process using a Ca2+ chelator.
Autophagy induction led to enlarged vacuoles with GFP-Rab11 and significant colocalization with LC3
Rab11 dominant negative mutant abrogated MVBs and autophagic interaction
Autophagy induction inhibited exosome release.
