Research interests

    HIV persists over decades despite seemingly effective antiretroviral treatment (HAART). HIV persistence relates to the fact that HIV integrates into the genome of the host cell, thus becoming an integral part of cellular DNA. Infected cells harboring a transcriptionally silent “latent” provirus evade immune surveillance and persist over many years despite long-term HAART. While there is agreement that memory CD4 T cells play a central role in HIV persistence, fundamental gaps remain in our understanding of how HIV latency is established and maintained.

    Emerging evidence suggest that CD4 T memory stem cells (TSCM), the least differentiated of all CD4 T cell memory populations, support HIV infection. However, the extent of the impact of TSCM on establishment of HIV latency, persistence and the underlying molecular mechanisms remain unknown. We hypothesize that HIV exploits the stemness of TSCM to create a persistent, self-renewing HIV reservoir, which bypasses the need for de novo infection. Understanding the molecular mechanisms underlying HIV persistence in CD4+ T memory stem cells is essential to develop targeted interventions allowing shrinking and purging of the latent reservoir.
