Dr. Diane Bolton received her Ph.D. from the NIH-Johns Hopkins University cooperative graduate program in 2006. She completed her postdoctoral fellowship on mucosal vaccine immunogenicity and gene expression analysis of virally infected cells with Dr. Mario Roederer at NIH’s Vaccine Research Center in Bethesda, Md.
Dr. Bolton’s interests focus on immune responses and viral dynamics during HIV/SIV vaccination and infection. Specifically, her team aims to explore the complex immune responses to vaccine regimens, such as that used in RV144, to elucidate cellular and humoral correlates of protection. Using the rhesus macaque model of HIV infection allows investigation of a broad range of responses in multiple tissues, including mucosal sites critical for HIV/SIV transmission. In addition to studying the immune response to the virus, we examine viral mechanisms underlying transmission, disease pathogenesis, and chronic infection. HIV/SIV preferentially infects CD4 T cells, but the specific subsets of these or other hematopoietic cells that harbor virus in vivo remain unknown, particularly at the time of infection. Such cell populations represent important targets for both preventative vaccines and therapeutic curative interventions. By characterizing active and latent viral infection within individual cells during acute and chronic disease we hope to lay the foundation for discoveries that limit HIV infection and disease progression. Advances in single-cell flow cytometric and gene expression technologies enable MHRP researchers to address these questions at the unprecedented single-cell level.
