Abstract: Programmed cell death-1(PD-1),as an inhibitory co-stimulatory molecule,is expressed on the surface of T lymphocyte membranes. After interacting with its main ligand,programmed death-1 ligand(PD-L1),PD-1 decreases immune response of T lymphocytes,and even damages the overall functioning of T lymphocytes. PD-1/PD-L1 signaling pathway plays an important role in the tolerance of T cell immune response triggered by hepatitis B virus infection. Studies indicate that blocking this pathway may provide an new insights into antiretroviral therapy,and might be a promising applications in clinical practice.
