Our research interests include the study of several factors that modulate inflammatory pathways in the female genital tract (FGT). We have identified cationic antimicrobial peptides that contribute to the anti-viral capabilities of vaginal fluid. Former student projects have also identified pro-HIV molecules produced by endocervical cells exposed to bacterial vaginosis-associated bacteria. Current studies include fractionation of these co-culture fluids in order to identify specific proteins effecting epithelial barrier function, NFkB activation, and chemotaxis of HIV target cells. We collaborate with faculty from UCF and abroad in the pursuit of therapeutics that provide potent anti-viral activity without disturbing the dynamic environment of the FGT mucosa. We are also a GCLP-certified specimen processing lab for the HIV Vaccine Trials Network, and perform clinical processing for several Orlando-area clinical trials.
