Abstract:
Objective To observe the effect of Shenxian Yiganling Tablets ( SYT) , a Chinese herbal recipe with the actions of tonifying kidney and removing toxicity, combined with HBsAg gene-modified dendritic cells (DC/HBsAg) on immune response and hepatocyte damage of hepatitis B virus (HBV) transgenic mice. Methods HBV transgenic mice ( Tg mice) were immunized with injection of DC/HBsAg ( 100 μg every three weeks) through caudal vein, and then were given intragastric administration of SYT in the dosage of 12.8, 23.5, and 47.0 mg/d for four weeks. HBV Tg mice splenic T cell cytokines of interleukin 2 ( IL-2) and interferon gamma ( IFN-γ) levels as well as serum alanine aminotransferase ( ALT) and aspartate aminotransferase ( AST) conents were detected by enzyme-linked immunosorbent assay ( ELISA) . Lactate dehydrogenase ( LDH) release assay was used to detect the in-vitro cytotoxic activity of splenic HBsAg specific T lymphocytes. Serum HBsAg level of HBV Tg mice was detected by ELISA after immunization. Results Compared with DC/HBsAg administration alone, DC/HBsAg combined with SYT could significantly increase HBV Tg mice splenic T cells cytokines IL-2 and IFN-γ levels ( P<0.05 or P<0.01) , increase the cytotoxic activity of HBsAg-specific T lymphocytes ( P<0.05 or P<0.01), increase the inhibition rate of HBsAg expression (P<0.05 or P<0.01), and reduce hepatocyte damage. Conclusion SYT could enhance the immune response of Tg mice to DC/HBsAg immunization, and relieve the hepatic damage, which enable the HBV clearance process out of hepatic damage in the case of anti-HBV activity of IFN-γbeing unaffected.
