Abstract: The H3 histamine receptor is a high‐affinity receptor reported to mediate inhibition of CNS histidine decarboxylase activity and depolarization‐induced histamine release. We have used (R)‐α‐[3H]methylhistamine, a specific, high‐affinity agonist, to characterize ligand binding to this receptor. Saturation binding studies with rat brain membranes disclosed a single class of sites (KD= 0.68 nM; Bmax= 78 fmol/mg of protein). Competition binding assays also yielded an apparently single… CONTINUE READING
