Professional Summary

HIV infection results in elevated microglial and astrocyte activation in the brain.  My long term goal is to explore the detailed molecular mechanisms/pathways that are responsible for over-activation of glial cells and identify potential targets for HAND treatment.

Research Interests

Autophagy is a highly conserved process in all eukaryotic cells.  In general, autophagy is a cellular homeostatic process that involves the sequestration of unfolded cytosolic proteins within the double-membrane-bound compartments (autophagosome) that are eventually destined for protein degradation.   Various neuroinflammation related diseases including HIVE involve with dysreguated autophagy levels.   Also, autophagy is well known for regulating innate immune response.   Cocaine and HIV-TAT have the ability to activate microglia and astrocytes, which in turn, increase neuroinflammation levels in the brain.  However, the underlying mechanisms for this phenomenon remain much unexplored.  To address on this interesting topic, I mainly focus on the functional link between autophagy and neuroinflammation under the context of cocaine & TAT.
