Interleukin (IL)-35, a new-discovered cytokine, can protect the liver from the environmental attack by increasing the ratio of Tregs (T regulatory cells) which can increase the anti-inflammatory cytokines and inhibit the proliferation of immune cellular. Also, IL-35 played crucial function in the process of liver diseases thought immunosuppressive regulation. When liver injury and inflammation occurred, two opposite mechanism, pro-inflammatory and anti-inflammatory, were in relation to the ultimate formation of diseases. Some obvious advantages indicate that IL-35 could be seen as a new therapeutic target to control the progression of liver diseases, but its mechanism of function still needs further research.
