Research Progress of Histone Deacetylase Inhibitor Combined with Immune Checkpoint Inhibitor in the Treatment of Tumor / 中国肺癌杂志

ABSTRACT

Immunotherapy is one of the main strategies of anti-tumor therapy at present, in which immune checkpoint inhibitors (ICIs) are the most widely used drug. ICIs resistance is mediated by a variety of cytokines and immune cells, and the mechanism is complex, which is the main reason for the failure of immunotherapy in cancer patients. Histone deacetylase inhibitor (HDACi), as a class of epigenetic regulatory drugs, plays an important role in regulating cell cycle, proliferation, differentiation, and activity. In recent years, Studies have found that HDACi can not only regulate cell biological characteristics, but also closely related to the improvement of tumor ICIs drug resistance. Therefore, the study on how HDACi enhances the efficacy of ICIs is of great significance to tumor immunotherapy. This article will review the research progress of HDACi combined with ICIs in treating malignant tumors and their related mechanism.
