Protein phosphatase 2A regulates apoptosis in neutrophils by dephosphorylating both p38 MAPK and its substrate caspase 3.
The induction of apoptosis in neutrophils is an essential event in the resolution of an inflammatory process. We found recently that the reduction of the activity of the neutrophil survival factor p38 MAPK and dephosphorylation and thus activation of caspases must occur to initiate such cell death in these leukocytes. Here, we report a previously undetected early and transient activation of protei
