The relevance of kalikrein-kinin system via activation of B2 receptor in LPS-induced fever in rats

LPS activates endogenous kalikrein-kinin system leading to production of BK, which by acting on B2-receptors of POA cells causes prostaglandin synthesis that in turn produces fever. Thus, a kinin B2-receptor antagonist that enters into the brain could constitute a new and interesting strategy to treat fever.
