Taurocholic acid (100 μM, 24 h) decreases the proportion of CD3+CD8+ T and NK cells in isolated PBMCs from HBeAg-positive CHB patients[2].
Taurocholic acid (100 μM, 24 h) decreases IFN-α stimulated cytokine and cytotoxic granule levels (IFN-γ, TNF-α, granzyme B) in CD3+CD8+ T and NK cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Taurocholic acid (1% in diet, 1 week) sodium prevents hepatic artery ligation (HAL)-induced cholangiocyte damage in rats by upregulation of VEGF-A expression[3].
Taurocholic acid can be used in animal modeling to create stress-induced gastric injury models and pancreatitis models[3][4][5].
Note:
Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.

Animal Model:C57BL/6 mice[2]
-
Dosage:100-mg/kg
-
Administration:oral gavage, for 2 weeks after tail vein injection with rAAV8-1.3HBV for 6 weeks
-
Result:Reduced the percentage of NK and CD3+CD8+ T cells.
Increases serum HBsAg, HBeAg, and HBV DNA levels.
Administration: 30-300 mg/kg • p.o • single dose.
The pylorus-ligated rats are then placed in cages with restricted movement.
Subsequently, the cages are immersed in a water bath maintained at 23°C until the water level reaches the xiphoid process of the rats, lasting for 7 hours.
Seven hours later, the animals are sacrificed under ether anesthesia, and the stomach of each animal is removed. The gastric contents are collected through the esophagus and analyzed for volume and acidity.
Administration: 1 mL/kg • retrograde infusion into the common pancreaticobiliary duct • at a speed of 0.25 mL/min[4]
Mice: Balb/c and Wistar • male • weighing 25-30 g and 250-300 g[5]
Administration: 1 mL/kg • retrograde infusion • perfusion for 8 h[5]
(2) Pancreatic acinar cells were isolated freshly from Balb/c or C57/BL6J mice using a collagenase IV. Cells were treated under room temperature, and used within 4 hours after isolation[2].
Biochemical Analysis: Taurocholic acid administration increased serum amylase and lipase activities[1].
