Bcl-(xL) antagonism of BCR-coupled mitochondrial phospholipase A(2) signaling correlates with protection from apoptosis in WEHI-231 B cells.

Abstract

Crosslinking of the antigen receptors on the immature B-cell lymphoma, WEHI-231, leads to growth arrest and apoptosis. Commitment to such B-cell receptor (BCR)-mediated apoptosis correlates with mitochondrial phospholipase A2 activation, disruption of mitochondrial function, and cathepsin B activation. CD40 signaling has been reported to rescue WEHI-231 B… (More)
