摘要

We have previously correlated Chlamydia trachomatis antiapoptotic activity with the blockade of mitochondrial cytochrome c release and the inhibition of Bax and Bak activation. We now report that C. trachomatis infection leads to degradation of Bik, Puma, and Bim, three upstream proapoptotic BH3-only proteins of the Bcl-2 family that can transmit death signals to mitochondria by inhibiting the Bcl-2 antiapoptotic proteins and/or activating the Bcl-2 proapoptotic members, such as Bax and Bak. This observation has provided new information on the chlamydial antiapoptosis mechanisms.
