Core Tip

Core tip: Currently there is no reliable model for chronic multiorgan inflammatory and fibrosis. Tumor necrosis factor (TNF)α initiates inflammation through TNFR1/R2. TNFR1/R2 deficient mice administered orally with dibutyltin dichloride (DBTC) developed significant persistent inflammatory and pain related secondary mechanical hypersensitivity. DBTC-animals showed severe chronic hepatobiliary injuries and prominent biliary ductal dilation. Extensive fibrotic thickening was evidenced around portal ducts, in hepatic and pancreatic structures. DBTC-animals had severe pancreatic damage and pancreatitis, hepatic lesions with expansion of gall bladder, bile stones and severe colitis. This is the first report of chronic inflammatory multiorgan hepatobiliary pancreatitis, fibrosis and calculi formation in TNFR1/R2 deficient mice.
