Abstract:

Lymphocyte activating gene 3 (LAG-3) is an important inhibitory immune checkpoint in vivo that ensures immune homeostasis by inhibiting various lymphocyte activation and cytokine secretion. However, tumor cells often use this to undergo immune escape and LAG-3 have currently been found to be highly expressed in many types of tumor-infiltrating lymphocytes. In this paper, the gene, structure and function of LAG-3 and the role of dual blockade of LAG-3 and programmed deathreceptor-1 in cancer immunotherapy will be described in order to provide further reference for cancer immunotherapy.

Key words: Immune checkpoint, Lymphocyte activating gene 3, Programmed deathreceptor-1, Cancer immunotherapy
