The uptake and release of γ-amino-n-butyric acid (GABA) in rabies virus-infected embryonic rat cortical neurons was assayed using tritiated ligands. A 45% reduction of [3H]GABA uptake was observed 3 days post-infection, when a maximum level of infectious particle release occurs. At this time, kinetic analysis revealed significant changes in V max, whereas no changes were found in K m values in comparison with the control values. K+ and veratridine-induced [3H]GABA release was increased in infected cultures (98% and 35%, respectively) as compared with control values. The results obtained from rabies virus-infected cultures provide some preliminary evidence of the involvement of GABA in the pathogenesis of rabies. %U https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-75-3-623
