Involvement of ryanodine receptors in muscarinic receptor-mediated membrane current oscillation in urinary bladder smooth muscle.
The urinary bladder pressure during micturition consists of two components: an initial, phasic component and a subsequent, sustained component. To investigate the excitation mechanisms underlying the sustained pressure, we recorded from membranes of isolated detrusor cells from the pig, which can be used as a model for human micturition. Parasympathomimetic agents promptly evoke a large transie...
متن کاملMuscarinic receptor-mediated bronchoconstriction is coupled to caveolae in murine airways.
Cholinergic bronchoconstriction is mediated by M(2) and M(3) muscarinic receptors (MR). In heart and urinary bladder, MR are linked to caveolin-1 or -3, the structural proteins of caveolae. Caveolae are cholesterol-rich, omega-shaped invaginations of the plasma membrane. They provide a scaffold for multiple G protein receptors and membrane-bound enzymes, thereby orchestrating signaling into the...
متن کاملP136: Role of Muscarinic Receptors in Schizophrenia
Schizophrenia is a severe psychiatric illness with a lifetime prevalence of ˜1% that imposes a huge toll on patients, their families and public health services worldwide. Delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior and negative symptoms constitute the core symptoms of schizophrenia. Although the neurotransmitter dopamine plays a prominent role in t...
متن کاملEicosanoid and muscarinic receptor blockade abolishes hyperventilation-induced bronchoconstriction.
This study was designed to test the hypothesis that hyperventilation-induced bronchoconstriction (HIB) results from the combined effects of prostanoid and leukotriene metabolism. A bronchoscope was used in anesthetized dogs to record peripheral airway resistance and HIB before and after combined treatment with inhibitors of cyclooxygenase (indomethacin) and 5-lipoxygenase (MK-0591). Bronchoalve...
متن کاملMuscarinic receptor binding and muscarinic receptor-mediated inhibition of adenylate cyclase in rat brain myelin.
High-affinity muscarinic cholinergic receptors were detected in myelin purified from rat brain stem with use of the radioligands 3H-N-methylscopolamine (3H-NMS), 3H-quinuclidinyl benzilate (3H-QNB), and 3H-pirenzepine. 3H-NMS binding was also present in myelin isolated from corpus callosum. In contrast, several other receptor types, including alpha 1- and alpha 2-adrenergic receptors, present i...
