Associate Professor of Medicine

Dr. Ramratnam's laboratory works on the pathogenesis of HIV-1 infection. Currently NIH funded projects are focused on better understanding the role of reproductive hormones on HIV-1 transmission (R01HD072693) and determining whether substance abuse alters a cell's capacity to support viral replication (P01AA019072). A separate interest is in better defining the cellular components of atypical responses to HIV such as those observed among individuals who become infected but are able to autonomously control viral replication.

Click on the thumbnail below to view a larger image of the slide.

Proteomic Determinants of HIV-1 Replication
The goal of this project is to determine whether the host proteome influences the activity of the integrated HIV-1 provirus in vivo. Host proteomes of individuals with various levels of plasma HIV-1 are being compared by the technique of SILAC before MS based quantification. Identified proteins are subsequently over/under expressed in HIV-1 reporter cells to identify their HIV-1 specific effects, if any.

Reproductive Hormones and HIV-1 Transmission
The goal of this project is to determine whether endogenous/exogenous hormones impact HIV-1 transmission. Several cohorts of HIV-1 uninfected women are being recruited and followed before/after starting birth control Cervical and vaginal biopsies are being performed and tissue are challenged with HIV-1 ex vivo In this manner, we will be able to determine whether reproductive hormones influence HIV-1 susceptibility of mucosal tissues in the female genital tract.

Alcohol and HIV
The goal of this project is to determine whether alcohol use alters the HIV-1 specific cellular machinery. HIV-1 dependency transcriptomes are being quantified in infected individuals with various levels of alcohol use. Alcohol use is objectively quantified by a PeTH blood test. The overall goal is to better understand the impact that alcohol may have on HIV-1 pathogenesis outside of issues surrounding medication adherence.
