Research Interests:


Dr. Henderson's major research interests are revolving around several projects. The first involves the etiology and evolution of EBV-associated T cell lymphomas in patients with AIDS. AIDS-related Epstein-Barr virus (EBV)-associated T cell lymphomas are emerging as a new, distinct histopathological entity. The pathway whereby EBV infects T cells as well as the initial EBV transcriptional program in T cells has not been established. Dr. Henderson's laboratory is actively working to characterize these pathways. Demonstration of EBV mRNA transcripts encoding immediate-early transcriptional transactivators in EBV-infected T cells provides the first evidence for a possible mechanism whereby EBV could contribute to T cell proliferation and EBV-associated T cell malignancies. Identification of EBV transcripts in T cell lymphomas will lead to improved therapy and prevention of these lymphomas.


The second research project is related to Herpesvirus saimiri. Human T lymphocytes are transformed by this virus in vitro to continuous proliferation. It has been previously shown that H. saimiri-transformed human T cell lines are a permissive system for HIV-1 and -2 replication and are highly susceptible to infection by HIV-1 and 2. Two proteins of H. saimiri, StpC and Tip, are required for T cell transformation and are unique to this herpesvirus. The successful transduction of human T cells with retroviral vectors expressing H. saimiri proteins StpC and Tip has allowed us to extend the before-mentioned observations and investigate the role of StpC and Tip in replication of HIV 1 T-tropic strains (IIIB, MN and RF) in human T cell lines. StpC expression in Molt4 dramatically enhanced HIV-1 replication. In contrast, Tip expression in Molt4 cells inhibited HIV-1 replication and cytopathic effects relative to Molt4 cells transduced with the empty vector alone. A better understanding of the effects of Tip and StpC proteins on the biology of human hemopoietic stem cells may lead to novel therapeutic interventions for the treatment of AIDS.
