BCL2L1 and Sepsis: To get more insight into the mechanisms of apoptosis inhibition in sepsis, neutrophils of naïve and septic (CASP 6 h) WT and TRAIL–/– mice were isolated, and expression analysis of the pro-apoptotic protein BAX and the anti-apoptotic proteins Bcl-Xl, c-IAP, MCL-1, survivin, and FLIP were performed by Western blotting.
