WebApr 12, 2004 · Lysosomes in cell death For many years apoptosis research has focused on caspases and their putative role as sole executioners of programmed cell death. … WebAutophagic function of lysosomes also helps indirectly in a process called apoptosis. Apoptosis - or programmed cell death - is when a cell becomes 'old', or gets infected by certain kinds of pathogens and receives the signal for self-destruction. The contents of the lysosome then 'spill' out into the cell and eat up the cell from the inside.

WebAutophagy-related proteins (ATGs) make autophagy possible. ATGs cause structures called autophagosomes to form. Autophagosomes carry the junk cell pieces to a part of the cell called a lysosome. A lysosome’s job is to digest or break down other cell parts. Imagine lysosomes — part of a cell — eating other parts of the cell. WebPrior to apoptosis induction, cells showed a diffuse cytosolic immunostaining of Bax (Figure 5a), and no co-localization of Bax with lysosomes was detected after overlay of images (Figures 5a-c).
