title: Catecholaminergic control of NK cell cytolytic activity regulatory factors in the spleen.
abstract: We examined the effects of norepinephrine (NE), isoproterenol (ISO) and metaproterenol (MP) on natural killer (NK) cell cytolytic activity and on the protein and mRNA levels of the regulatory factors perforin and granzyme B and interferon-gamma (IFN-gamma) in splenocytes. NE, the beta-adrenergic agonist ISO, and the beta 2-selective-agonist MP all inhibited the protein and mRNA levels of perforin, granzyme B and mRNA levels of IFN-gamma. NE inhibited NK cell cytolytic activity as well. Furthermore, MP inhibition of granzyme B mRNA was blocked by the beta-antagonist nadolol. These data suggest that NE and beta-adrenergic agonists may inhibit NK cell cytolytic activity by regulating the production of perforin, granzyme B, and IFN-gamma in splenocytes.
