Research Interests

Neurologic consequences of HIV infection:

My research interests center about the role of extra cellular vesicles (EVs) in the pathogenesis of HIV.  We have shown that the expression of HIV protein Nef in HEK293 cells induces the production of EVs.  Our latest research suggests that EVs play a role in the pathogenesis of HIV associated neurological disorders (HAND). Brain cells (SH-SY5Y) treated with Nef EVs secrete more amyloid beta.  Since amyloid beta has been associated with cognitive disorders it could provide a link between HIV infection and neurological dysfunction.

This project is funded in part by NIMHD grant 5R21NS105577

Traditional African treatment for HIV/AIDS:
We have also been working with traditional healers in Senegal (Prometra) to investigate an herbal treatment for HIV/AIDS.  We have shown that water soluble extracts from medicinal plants contain a potent antiviral activity.  We are working to understand the mechanism of action of these plant extracts as a potential treatment for HIV/AIDS.  We are also interested in other medicinal plants to better understand these alternative treatments.

Core facilities:
I am also involved in the management of the Research Infrastructure Core (RIC) at 黑洞社区 of Medicine.  This facility was recently funded through a U54 grant from NIH (2U54 MD007602)
