Drug abuse and central nervous system (CNS) plasticity with emphasis on the effects of opioids in the context of neuro-acquired immunodeficiency syndrome (neuroAIDS) and the modulation of human immunodeficiency virus type 1 (HIV-1) neuropathogenesis; developmental neurobiology; glial biology; neuroimmunology; endogenous opioids and the pathobiology of dynorphins
Our research attempts to understand the mechanisms by which drug abuse causes lasting changes in CNS organization and function. During development, as well as in the mature brain, we have found that drug abuse can disrupt the production and organization of neurons and glia. We propose that the organizational changes are maladaptive and especially revealed when the drug-exposed CNS is further challenged with insults such as disease, trauma, and/or aging.
The effects of substance abuse to CNS function are particularly evident in individuals infected with HIV-1. Opioid abuse can dramatically exacerbate the neuroinflammatory and neurodegenerative consequences of HIV-1. We discovered that opioid drugs can interact synergistically with HIV-1 proteins to directly increase neuronal injury and death. Our lab also found that opioids can potentiate the production of inflammatory and excitotoxic molecules in HIV-1-exposed microglia and astroglia, which further contribute to neuronal damage. These studies have also added significant insight into mechanisms underlying the pathogenesis of neuroAIDS in non-substance abusers. To tackle these problems, a wide variety of cell, molecular, genetic, neuropharmacological, and neuroimmune strategies are used to understand the complex mechanisms by which substance abuse and HIV-1 disrupt the nervous system.
