TaurocheNODeoxycholic acid sodium 是动物胆汁酸的主要生物活性物质之一。它可诱导细胞凋亡，具有抗炎和免疫调节作用。

Sodium taurochenodeoxycholate is one of the main bioactive substances of animals' bile acid. Sodium taurochenodeoxycholate induces apoptosis and shows obvious anti-inflammatory and immune regulation properties. It can increase glucose-induced insulin secretion and stimulate the electrical activity of α2-cells and enhance cytosolic Ca(2+) concentration ([Ca(2+)](c)).

Experiments were performed with islets from wild-type, farnesoid X receptor (FXR) knockout (KO), and β-cell ATP-dependent K(+) (K(ATP)) channel gene SUR1 (ABCC8) KO mice, respectively. Sodium taurochenodeoxycholate (TCDC) increased glucose-induced insulin secretion. This effect was mimicked by the FXR agonist GW4064 and suppressed by the FXR antagonist guggulsterone. TCDC and GW4064 stimulated the electrical activity of β-cells and enhanced cytosolic Ca(2+) concentration ([Ca(2+)](c)). These effects were blunted by guggulsterone. Sodium ursodeoxycholate, which has a much lower affinity to FXR than TCDC, had no effect on [Ca(2+)](c) and insulin secretion. FXR activation by TCDC is suggested to inhibit K(ATP) current. The decline in K(ATP) channel activity by TCDC was only observed in β-cells with intact metabolism and was reversed by guggulsterone. TCDC did not alter insulin secretion in islets of SUR1-KO or FXR-KO mice. TCDC did not change islet cell apoptosis.
