Abstract:

Immune system plays a pivotal role in disease development during chronic virus infection. On one hand, the immune system defends against infectious agents through effector immune cells and molecules. On the other hand, the immune system has negative immune regulation mechanisms to suppress immune response and prevent its overactivation. However, these mechanisms may oversuppress and hamper the generation of effective antiviral immune responses during chronic viral infection. In this review, the function of immunosuppressive molecules programmed cell death protein-1 (PD-1) and its ligand PD-L1 during chronic viral infections were discussed, and recent advances in immune therapies targeting these molecules were summarized.

Key words: Programmed cell death protein-1, Immunotherapy, Chronic virus infection
