Chlamydia trachomatis infection inhibits both Bax and Bak activation induced by staurosporine

Infect Immun. 2004 Sep;72(9):5470-4. doi: 10.1128/IAI.72.9.5470-5474.2004.

Abstract

We have previously shown that Chlamydia trachomatis inhibits host cell apoptosis and blocks mitochondrial cytochrome c release. We now report that activation of both Bax and Bak, two proapoptotic members of the Bcl-2 family that regulate mitochondrial cytochrome c release, was inhibited in chlamydia-infected cells. This observation has provided new information on the mechanisms of chlamydial antiapoptotic activity.
