The lateral septal nucleus (LS) presents a dense plexus of fibers containing substance P (SP), which is known to induce pronounced anxiogenic-like effects when applied into this brain site. In the present report, we investigated the role of lateral septal

To evaluate whether neutral endopeptidase (NEP) inhibitors have adverse respiratory effects, the influence of a NEP inhibitor on bradykinin (BK)-induced bronchoconstriction was investigated. In anesthetized and artificially ventilated guinea pigs, changes in airway opening pressure (Pao) were measured as an

Although neurogenic inflammation of the airways via activation of C-fibers is thought to be important in the pathogenesis of asthma, the mechanisms regulating C-fiber activity remain uncertain. The influence of a cannabinoid receptor agonist, WIN 55,212-2, on C-fiber activation in

We have reported previously that bradykinin (BK) induces potent and reproducible concentration-dependent contractions of the pig iris sphincter (PIS) muscle in vitro through the activation of BK B(2) receptors. Here we attempted to investigate additional mechanisms by which BK induces
