Research Interests

The current research efforts in the laboratory include:

1. Intranasal based vaccine approach against genital Chlamydia trachomatis infection.
C. trachomatis is an obligate intracellular bacterium that is a leading cause of sexually transmitted disease. C. trachomatis infections have a high prevalence of morbidity and are also associated with pelvic inflammatory disease that often result in infertility. Despite considerable effort in the understanding of the pathogenesis of the disease, an efficacious chlamydial vaccine has not been attained. We have provided evidence to demonstrate the use of proteasome-like activity factor (CPAF) and IL-12 to induce robust Th-1 mediated immunity against C. trachomatis infection. We are currently evaluating cellular and humoral immune responses and examining the mechanistic contribution of IgA in intracellular neutralization of CPAF activity during C. trachomatis genital infection. Overall, these studies will provide valuable immunoregulatory insight into the design of viable vaccines against sexually transmitted disease.
2. Respiratory defenses against pulmonary tularemia.
Francisella tularensis is an intracellular bacterium that is the causative agent of tularemia. Inhalation exposure or respiratory infections with these bacteria are highly fatal due to the low infectious dose. There is limited information on localized respiratory defenses to F. tularensis. We are currently characterizing the use of a defined F. tularensis mutant as a live attenuated vaccine candidate against pneumonic tularemia. Additionally we are examining the feasibility of using locally administered combinatorial immunotherapy against aerosolized tularemia.
