Research Interests

The major determinants of HIV pathogenesis leading to AIDS remain unclear.  However, a growing body of experimental evidence suggests that the HIV/SIV protein Nef plays a key role in virus-induced pathogenesis. Understanding the viral and cellular determinants underlyng pathogenesis leading to AIDS is a critical step in finding new targets for therapy to slow or stop progression to AIDS.  For the last fifteen+ years, Dr Bond’s lab in collaboration with Dr Michael Powell have been investigating the role played by extracellular Nef, secreted from HIV (or SIV/HIV-2) infected cells in extracellular vesicles (EV’s; exNef), in pathogenesis leading to AIDS. This work has entailed molecular genetics, computation chemistry using supercomputer modeling, translational/population studies involving patient plasma analysis, humanized mouse studies of infection, and monkey studies with collaborators at University of California, Davis, and Emory CFAR Clinical Core, immunological analysis of human infection and nonhuman primate infections with collaborators at University of Louisiana, Layfette Primate Center.

A body of literature arising from these collaborative, funded studies has begun to uncover the detailed mechanism(s) by which the Nef protein is released from viral-infected cells in EV’s that result in, depending on the cell type, (i) activation-induced cell death, or (ii) gene dysregulation leading to unscheduled immune activation, both in bystander cells. These uncovered mechanisms are capable of leading to immune depletion/dysfunction causing pathogenesis leading to AIDS. This research program has highlighted at least one potential new target for AIDS therapy, and a therapeutic peptide inhibitor. Additionally, understanding the role of/mechanisms underlying the cellular trafficking pathway in the HIV lifecycle has opened new avenues of study into this basic and important cellular function, relevant to understanding and addressing other disease processes including cancer pathogenesis, and bacterial biofilm formation/pathogenesis.
