title: Age-related changes of beta-adrenoceptors in aging inbred mice.
abstract: The density (Bmax) and antagonist dissociation constant (KD) of beta-adrenoceptors were determined on spleen and brain of three different inbred strains of mice--BALB/cJ, C3H/HeJ, and C57BL/6J. Receptor densities (Bmax) differed with strain and declined in both spleen and cortical receptor populations as mice became older. Age-related changes in KD were found on spleen cells of BALB/cJ and in the cortex of C3H/HeJ and C57BL/6J. Bmax and KD in different organs of the same strain changed at different rates. changed at different rates.
