Abstract:
AIM This study was undertaken to investigate the protective effect against ConcanavalinA (ConA) or BCG+LPS induced liver injury in mice by FTY720 and possible mechanisms. METHODS The serum ALT and its AST level changes were measured in two kinds of immunological liver injury models. The serum IFN ? and IL 4 changes were determined by ELISA and tested the effect of FTY720 on lymphocyte proliferation. RESULTS FTY720 dose dependently reduced serum ALT, AST levels in ConA or BCG+LPS induced liver injury in mice. It was also found that FTY720 decreases serum IFN ? and IL 4 levels during liver injury. The results also proved that FTY720 was able to inhibit lymphocyte proliferation. CONCLUSION Pretreatment with FTY720 could protect the mice from immunological liver injury. The possible mechanisms of its action are related to inhibiting lymphocyte proliferation and cytokines production.
