Abstract
In a CNS[central nervous system]-derived [glioma C-6] cell line, the cellular response to hormonal [isoproterenol] stimulation, represented by the rise of intracellular c[cyclic]AMP levels, is impaired under the influence of a persisting neurotropic virus infection. This dysfunction is caused by the decrease in adenylate cyclase activity, most probably due to the virus-induced loss of active catalytic units.
