title: Beta2-adrenoceptors on the glial cells mediate the induction of interleukin-1beta mRNA in the rat brain.
abstract: Interleukin-1beta mRNA was induced by i.c.v. injection of the beta-adrenoceptor agonist isoproterenol. Lower doses of procaterol, a beta2-adrenoceptor agonist showed stronger induction of the mRNA than isoproterenol. These inductions were primarily observed in the glial cells. On the other hand, the beta1-adrenoceptor agonist dobutamine induced expression of this mRNA only in the meninges. These results suggest the existence of a system for regulation of interleukin-1beta gene expression via beta2-adrenoceptors in the brain parenchyma.
