How microglia kill neurons.
Cambridge, United Kingdom. In Brain Res, Jan 2016
A number of mechanisms by which activated microglia kill neurons have been identified, including: (i) stimulation of the phagocyte NADPH oxidase (PHOX) to produce superoxide and derivative oxidants, (ii) expression of inducible nitric oxide synthase (iNOS) producing NO and derivative oxidants, (iii) release of glutamate and glutaminase, (iv) release of TNFα, (v) release of cathepsin B, (vi) phagocytosis of stressed neurons, and (vii) decreased release of nutritive BDNF and IGF-1.

The polypeptide copolymers were stable in the phosphate buffered saline, but the presence of proteolytic enzymes such as elastase, cathepsin B, cathepsin C, and matrix metallopreoteinase accelerated their degradation.
Stat3 controls lysosomal-mediated cell death in vivo.
Cambridge, United Kingdom. In Nat Cell Biol, 2011
Furthermore, although cell death through LMP is independent of executioner caspases 3, 6 and 7, it requires Stat3, which upregulates the expression of lysosomal proteases cathepsin B and L, while downregulating their endogenous inhibitor Spi2A (ref.
