Research Summary

The Chang lab is interested in the role of innate immunity in sexually transmitted infection-mediated enhancement of HIV infection, and HIV infection of human peritoneal macrophages.

Innate immunity in sexually transmitted infection-mediated enhancement of HIV infection
Sexual transmission is the most common route of HIV infection and women account for nearly half of those infected worldwide. Prevention strategies employing different approaches are needed to reduce the probability of transmission. Epidemiologic and clinical studies strongly indicate that sexually transmitted infections (STIs) increase the likelihood of HIV transmission. Although the contribution of STIs to the increase in HIV transmission is likely to be multifaceted, understanding how STIs enhance HIV infection is vital to the development of new strategies for the prevention of HIV. Our program focuses on dissecting the role of innate immunity (e.g defensins and Toll-like receptor activation) in modulation of HIV infection in the setting of STIs. We have shown that induction of human defensins 5 and 6 as well as TLR2 activation enhance HIV infection of various primary cells in response to STIs. The goal of this program is to dissect the underlying molecular mechanisms and to understand the complex function of innate immunity in mucosal transmission of HIV.

Regulation of innate immunity, microbiome and HIV transmission by hormones
Sex hormones modulate immune responses and HIV transmission. We are interested in delineating the mechanism by which sex hormones (estrogen and Depo-Provera) modulate HIV infection/transmission using in vitro and ex vivo models. A recently funded program is to understand the role of Depo-Provera in increased risks of HIV acquisition and transmission. We hypothesize that injectable DMPA alters immune responses and cervicovaginal and colonic microbiomes, which may lead to increased HIV acquisition and transmission. The aims of the Depo-Provera program are designed to (1) determine the impact of Depo-Provera on the systemic and mucosal immune systems and on cervicovaginal and colonic microbiomes in a longitudinal study, and (2) to elucidate the immune mechanisms of MPA-mediated modulation of HIV infection/transmission in vitro, ex vivo and in cervical explant models. The results of our studies will provide a better understanding of how DMPA modulates immunologic responses and microbiomes, thereby informing the design of effective HIV prevention strategies.

HIV-human peritoneal macrophage interaction
Macrophages, one of the major cell types in which HIV can both productively replicate and persist in a latent state, play a crucial role in HIV pathogenesis. Because the long-lived HIV reservoirs constitute a major obstacle to HIV eradication, the aim of this program is to understand the cellular and molecular mechanisms underlying HIV-macrophage interactions, which is essential for developing novel and efficacious therapeutic strategies against HIV infection. We have demonstrated that peritoneal macrophages (PMs) with unique properties are highly abundant in ascitic fluid of patients with cirrhosis, and are susceptible to HIV-1 infection. The project is to dissect the underlying mechanisms of dynamic HIV co-receptor usage in PMs, and to establish the contribution of PMs to HIV reservoirs. The outcome of this study will enhance our understanding of the role of macrophages in HIV pathogenesis and may facilitate discoveries of new strategies for treatment.
