Overview
Despite the success of antiretroviral therapy to control HIV infection, the latent reservoir formed by this virus remains the main barrier to a complete cure. Our laboratory studies the molecular mechanisms of HIV latency establishment and maintenance in human primary CD4+ T cells. We aim to determine how gene expression profiles in phenotypically different cells influence the proviral state and its ability to reactivate from latency. Currently, we focus on investigating the roles of long non-coding RNAs in the regulation of HIV gene expression and latency. We use the in vitro primary T cell models of HIV latency and CD4+ T cells obtained from people with HIV. Our most recent study has focused on delineating the heterogeneity of the latent reservoir cells using single-cell RNA-Seq technology coupled with immunophenotyping. Within these heterogeneous cell populations, we aim to identify molecular signatures (“a biomarker”) of latency that can define latently infected cells. This knowledge will likely lead to the development of approaches to capture the latently infected cells and, ultimately, to target them for elimination.

Altmetrics Details
PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media.
(Note that publications are often cited in additional ways that are not shown here.)
Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication.
Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication.
Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.)
