WebMay 14, 2024 · In a previous study, we found that LAMP2 was translocated from lysosomes to the cytosol during LMP-induced apoptosis 23 raising questions if lysosomal membrane proteins are actively or passively ... 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. coaches from birmingham to minehead

Autophagy as a decisive process for cell death Experimental ...

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. WebApoptosis is the major mechanism by which eukaryotic organisms eliminate potentially dangerous, superfluous and damaged cells. Initially, nuclei and mitochondria were found to be the key organelles involved in the process. However, recent data suggest that lysosomes and the endoplasmic reticulum also play important roles in the process.
