Abstract Ischemic brain injury and epilepsy are common neurodegenerative diseases caused by excitotoxicity. Their pathogenesis includes microglial production of inflammatory cytokines. Our studies were designed to examine whether a growth compromised HSV-2 mutant ARR prevents excitotoxic injury through modulation of microglial responses by the anti-apoptotic HSV-2 protein ICP10PK. EOC2 and EOC20 microglial cells which are differentially activated were infected with ARR or the ICP10PK deleted virus APK and examined for virus-induced neuroprotective activity. Both cell lines were non-permissive for virus growth but expressed ICP10PK ARR or the PK deleted ICP10 protein p95 APK . Conditioned medium CM from ARR- but not APK-infected cells prevented N-methyl-D-aspartate NMDA -induced apoptosis of primary hippocampal cultures as determined by TUNEL and caspase-3 activation 76.9 5.3 neuroprotection . Neuroprotection was associated with inhibition of TNF-a and RANTES and production of .
