Research Interest

HIV-1 invades the brain in the early stages of infection and productively infects brain mononuclear phagocytes (MPs: macrophages and microglia). The virus, secreted proteins “virotoxins” and inflammatory cytokines/chemokines produced by infected MPs are thought to induce neuronal dysfunction and HIV-associated dementia (HAD). To elucidate the pathogenesis of HAD, it is important to understand by what mechanisms HIV-1 invades the brain.

Our laboratory is currently using different experimental paradigms to decipher the mechanisms mediating in blood-brain barrier (BBB) dysfunction and virus invasion of the central nervous system (CNS) in HAD. These approaches include specific cytotoxic effects of HIV-1 and virotoxins on the brain endothelium (including functional alterations of cytoskeleton and tight junction proteins) leading to increased BBB permeability, role of chemokine receptors and events occurring within endothelial cells during interaction with HIV-1 infected cells.
