Abstract:
In recent years, tumor biological immunotherapy has rapidly become a hot topic in the field of cancer research owing to its remarkable therapeutic effects. Programmed death-1 (PD-1) and its ligand (PD-L1) are overexpressed in a variety of tumor cells and are involved in tumorigenesis, development, invasion, and metastasis. Therefore, blocking the PD-1/PD-L1 signaling pathway has become a promising new target for tumor immunotherapy. At present, PD-1/PD-L1 inhibitors have exhibited remarkable therapeutic effects in the treatment of lymphoma. This paper reviews the current status of clinical research on these drugs in order to enhance the understanding of the mechanism of PD-1/PD-L1 signaling pathway and the applications of relevant antibodies for the treatment of lymphoma.
