title: [Apoptosis of host cells regulation by Chlamydia].
abstract: In a study on the impact of chlamydial infection on host cell apoptosis, C. trachomatis were shown to protect host cell against staurosporin-induced apoptosis only at the middle stage of infection development (at 20 hours post infection), C. pneumoniae--at different stages of its growth cycle (from 2 to 7 day post infection). We found, that C. trachomatis elementary bodies fail to inhibit staurosporin-induced apoptotic stimuli. The clear antiapoptotic effect of cell lysate filtrate, infected with C. trachomatis, was demonstrated by cytometric analysis and luminescent microscopy. Our findings make it possible to use biochemical approach to identification of chlamydial antiapoptotic factors in future. Investigations directed at chlamydial antiapoptotic activities may aim to create the therapies of chronic chlamydial infection.
