Accepted 11 april 2006. viagra for sale Abstract interstitial cystitis (ic) is a chronic bladder inflammatory disease of unknown etiology that shares similarities with crohn's disease and psoriasis. viagra coupon Ic, often regarded as a neurogenic cystitis, is associated with urothelial lesions that likely compromise the bladder permeability barrier and thereby contribute to patient morbidity. yahoo email virus viagra Here, we use a murine model of neurogenic cystitis to investigate the mechanism of urothelial lesion formation and find that urothelial apoptosis induces formation of lesions. Lesions formed in wild-type mice but not in mice deficient in tnf, tnf receptors, or mast cells. In urothelial cultures, only sirnas targeting tnfr1, but not tnfr2, blocked tnf-induced apoptosis, indicating a primary role for tnfr1. can viagra and alcohol be mixed Trans-epithelial resistance, a measure of bladder barrier function, decreased during neurogenic cystitis in wild-type and tnfr2−/− mice but was stabilized in tnf−/− mice. Anti-tnf antibodies both altered bladder mast cell localization and stabilized barrier function. viagra 20 dollars a pill Based on these findings, we conclude that mast cell activation and release of tnf drive urothelial apoptosis and lesion formation in a murine neurogenic cystitis model, and we hypothesize that anti-tnf therapy may stabilize bladder barrier function in ic patients.
