Abstract
We quantitatively determined the receptors for histamine H1, histamine H2, alpha- and beta-adrenergic, prostaglandin E2 and F2 alpha in liver plasma membranes. The number of the receptors was the greatest in histamine H1 receptors (4740 +/- 750 fmol/mg protein) and the second in alpha-adrenergic receptors (965 +/- 16). Although relatively small numbers of the receptors were observed for histamine H2 (116 +/- 11) and prostaglandin E2 (38.0 +/- 8.9), we could not determine the number and affinity of beta-adrenergic and prostaglandin F2 alpha receptors. In contrast to the number of receptors, there was not significant difference in the affinities of receptors for histamine H1, histamine H2, alpha-adrenergic hormone and prostaglandin E2. These results suggest that histamine and its receptor play some role in liver function.
