Sphingolipids are a class of lipids enriched in the central nervous system that have important roles in signal transduction. Recent advances in our understanding of how sphingolipids are involved in the control of life and death signaling have uncovered roles for these lipids in the neuropathogenesis of HIV-associated neurocognitive disorders (HAND). In this review we briefly summarize the molecular mechanisms involved in the pathological production of the toxic sphingolipid, ceramide and address questions of how cytokine and cellular stress pathways that are perturbed in HAND converge to deregulate ceramide-associated signaling.
