Fast-replicating neurotropic herpesviruses exemplified by herpes simplex virus-1 (HSV-1) naturally infect the central nervous system (CNS). However, most individuals intrinsically suppress the virus during a primary infection and preclude it from significantly damaging the CNS. Optineurin (OPTN) is a conserved autophagy receptor with little understanding of its role in neurotropic viral infections. We show that OPTN selectively targets HSV-1 tegument protein, VP16, and the fusion glycoprotein, gB, to degradation by autophagy. OPTN-deficient mice challenged with HSV-1 show significant cognitive decline and susceptibility to lethal CNS infection. OPTN deficiency unveils severe consequences for recruitment of adaptive immunity and suppression of neuronal necroptosis. Ocular HSV-1 infection is lethal without OPTN and is rescued using a necroptosis inhibitor. These results place OPTN at the crux of neuronal survival from potentially lethal CNS viral infections.
