Am J Physiol Regul Integr Comp Physiol 283:R663-8. 2002..Thus in normal bladders both M(2) and M(3) receptors can induce contraction. In the denervated bladder, the M(2) and the M(3) receptors interact in a facilitatory manner to mediate contraction...

Department of Urology, Temple University School of Medicine, Philadelphia, PA 19140, USA
J Pharmacol Exp Ther 316:875-80. 2006..In the denervated bladder, the rho kinase pathway is more dominant than in normal bladders. PKA seems to mediate a contractile response in normal bladders, whereas it seems to inhibit contraction in denervated bladders...

Department of Pharmacology and Pharmacotherapy, University of Amsterdam, The Netherlands
J Pharmacol Exp Ther 322:998-1002. 2007..We conclude that previously reported differences relate to the use of inhibitors rather than experimental protocols and that the overall data do not support a role for PLC in M(3) muscarinic receptor-mediated rat bladder contraction...
