Neuronal damage and neuroinflammation is a hallmark feature of HIV-associated neurological disorders (HANDs). Opioids abuse accelerates the incidence and progression of HAND; however, the mechanisms underlying the potentiation of neuropathogenesis by these drugs remain elusive. Extracellular vesicles (EVs) are essential conduits in HIV and drug abuse-mediated synaptodendritic injury and neuroinflammation. Findings from our group have demonstrated that astrocyte-derived EV (ADEV)-miRNA-29b mediates HIV Tat and morphine-induced neuronal injury, thus underscoring the importance of such interactions in NeuroHIV.
Besides, HIV Tat and morphine-mediated synaptodendritic injury via ADEVs, we are also interested in whether ADEVs contributes to neuroinflammation. Microglia are critical players in …

Multiple sclerosis (MS) is a complex neurological disorder characterized by the interactions between heightened inflammation, oxidative stress and neurodegeneration. We and others have previously demonstrated that proteasome dysfunction and its consequences are also important factors in the pathology of both MS and its rodent model, experimental autoimmune encephalomyelitis (EAE). While proteasome subunit alterations in EAE have been observed, the underlying mechanisms are poorly understood. The first goal of this dissertation was to characterize the mechanisms that regulate proteasome expression and composition in neural cells in EAE and in vitro.
