Research Research in the Darville lab is focused on increasing our understanding of immune signaling pathways active in development of genital tract disease due to Chlamydia trachomatis and determination of chlamydial antigen-specific T cell responses that lead to protection from infection and disease. In vitro, murine model, and human studies are being performed with the ultimate goal to improve the sexual health of persons worldwide. Genetic and transcriptional microarray studies are being performed to explore pathogenic mechanisms and determine biomarkers of pelvic inflammatory disease due to Chlamydia as well as other sexually transmitted pathogens.
