We demonstrated that HIV infection of astrocytes protects infected cells from apoptosis but results in cell death of surrounding uninfected astrocytes by a mechanism that is dependent on gap junction channels, dysregulation of mitochondrial cytochrome C (CytC), and cell to cell diffusion of inositol trisphosphate (IP3) and calcium. Our data provide essential information about generation of brain reservoirs and the mechanism of toxicity mediated by the virus.
