It has been reported that lentiviral delivery of meteorin protects striatal neurons against excitotoxicity and reverses motor deficits in rats treated with quinolinic acid [37], and recombinant meteorin can promote the migration of neuroblasts from the subventricular zone explants of postnatal rats and stroke-subjected adult rats and reduce N-methyl-D-aspartate-induced apoptotic cell death of subventricular zone cells in vitro [38]. The gene discussed is METRN; the disease is stroke disorder.
