The kallikrein-kinin system is involved in the inflammatory process, in blood pressure regulation, and in renal homeostasis. The presence of kallikreins, kininogens, and kinins in renal tissues and fluids is well established; however, the occurrence and distribution of the bradykinin (B2) receptor in the kidney are unknown. Using chemically cross-linked conjugates of bovine serum albumin and the B2 agonist bradykinin or the potent B2 antagonist HOE140, followed by antibodies to the respective ligand and the peroxidase-anti-peroxidase system, we were able to detect the B2 receptor. The receptor has been found in straight portions of the proximal tubules, in distal straight tubules, in connecting tubules, and in collecting ducts of rat kidney. The staining patterns produced by the ligand conjugate-antiligand approach are in agreement with those obtained by conventional autoradiography using [125I]-Tyr0-bradykinin. Immunocytochemical localization of B2 receptor by antipeptide antibodies to the receptor confirmed these findings and demonstrated the presence of B2 receptor in the basal infoldings and luminal membranes of the tubule cells, and in smooth muscle cells of the cortical radial artery and of afferent arterioles. Co-localization of the B2 receptor with kallikrein and kininogens in connecting tubule cell and collecting duct cell layers, respectively, provides a structural basis for the hypothesized physiological functions of the kallikrein-kinin system in the kidney.
