IL6 and chlamydia trachomatis infectious disease: This project aimed to investigate the innate and adaptive cellular responses to these two proteases and chlamydial infections to test the hypothesis that they may be antigens which are involved in driving the initial innate pathological response to Chlamydia. In both laboratory model cell cultures and primary reproductive cell culture of epithelia or mononuclear cells we observed induction of IL-6 in response to stimulation with these proteins or with C. trachomatis.
