The role of kinin system in joint inflammatory disease.
Components of the kallikrein-kininogen-kinin are activated in response to noxious stimuli (chemical, physical or bacterial), which may lead to excessive release of kinins in the synovial joints that may produce inflammatory joint disease. The inflammatory changes observed in synovial tissue may be due to activation of B2 receptors. Kinins also stimulate the synthesis of other pro-inflammatory agents (PGs, LTs, histamine, EDRF, PGI2 and PAF) in the inflamed joint. B2 receptor antagonists may provide valuable agents as new analgesic drugs. Further, it is suggested that substances directed to reduce the activation of KKS may provide a pharmacological basis for the synthesis of novel anti-rheumatic or anti-inflammatory drugs.
