Research advances in immune tolerance in chronic hepatitis B virus infection / 临床肝胆病杂志

ABSTRACT

Immune tolerance refers to the specific non-response or negative response of T and B lymphocytes to antigens.According to the period of formation,immune tolerance can be classified into central tolerance and peripheral tolerance.Immune tolerance to hepatitis B virus (HBV) after HBV infection is considered a major cause of chronic HBV infection.This article briefly reviews the roles of HBeAg,functional defects of dendritic cells,low response of cytotoxic T lymphocytes,T helper cells and cytokines,variations of HBV genotype and genome,and host gene polymorphisms in the development of immune tolerance in chronic HBV infection,as well as related research advances.
