Abstract
Neuronal loss, alterations in dendritic arbor, and decreased synaptic density, in infected brain tissue, are neuropathological signatures of HIV-1-associated dementia (HAD). Brain mononuclear phagocyte (MP) (macrophage and microglia) secretory products can effect neuronal compromise, although the underlying mechanism(s) remain incompletely defined. To these ends, we quantitatively assessed the effects of virus-infected and/or immune activated MP secretory products on multiple aspects of neuronal morphology. Rat cortical and hippocampal neurons were exposed to secretory products from HIV-1-infected and lipopolysaccharide (LPS)-activated human monocyte-derived macrophage (MDM). Our assays for alterations in neuronal dendritic arbor and cell loss included the quantification of neurofilament (NF), neuron-specific enolase (NSE), and MAP-2 by ELISA and cellular morphology. MDM conditioned media (MCM) enhanced neuronal survival. HIV-1 infection or activation by LPS had modest neurotoxic effects. In contrast, the combination of HIV-1 infection and activation of MDM produced significant neurotoxicity. Such MDM products altered dendritic arbor, decreased synaptic density, and increased LDH release. Comparable neurotrophic/toxic responses were observed when neurons were exposed to MCM collected from 12 separate human donors. Similar responses were observed with MCM from human fetal microglia, further supporting the role of HIV-1-infected and immune-activated brain MP in the overall neurotoxic responses. This work provides quantitative measures of neuronal damage by which virus infected and activated MP can elicit neuronal injury in HAD.
