Recent evidence suggests an important role for kinins in the generation of pain, swelling and the cellular damage associated with inflammatory joint disease. Speculations about the role of kallikreins and kinins in hemodynamic, excretory, and metabolic processes originated in 1909 when the hypotensive property of human urine, now known to represent excreted renal kallikrein, was discovered. Their essential role in multiple physiological and pathological processes is demonstrated by activating two transmembrane G-protein-coupled receptors, the kinin B 1 and B 2 receptors. The mechanisms underlying ACE inhibitor-induced cough are probably linked to suppression of kininase II activity, which may be followed by an accumulation of kinins, substance P and prostaglandins. 355.
