Lysosomes as 'suicide bags' in cell death : myth or reality?

In this work we have critically evaluated the role of lysosomes and lysosomal cathepsins in three major types of cell death, apoptosis, necrosis and autophagy, although the latter is probably not a cell death mechanism, but a survival one. The article is based also on our previous results.

Cysteine cathepsins are not critical for TNF-alpha-induced cell death in T98G and U937 cells.

TNF is a cytokine known to be an important mediator of apoptosis and inflammation in a number of diseases. TNF apoptosis has been known to be critically dependent on caspases; however, it has been recently suggested that cysteine cathepsins might also be involved in the pathway. Based on the use of caspase inhibitors, TNF-alpha induced caspase-dependent apoptosis, accompanied by lysosomal destabilization and the release of cathepsins in the cytosol. However, use of cathepsin inhibitors E-64d and CA-074 revealed that cysteine cathepsins only marginally affect the progression of apoptosis.
