Post-translational modifications of proteins and cancer immunotherapy

Post-translational modifications (PTMs) of proteins is an important mode of protein function regulation, which is essential for the structure and function of proteins under physiological and pathological conditions, and the types of modifications is wide. Cancer immunotherapy refers to an effective method for cancer treatment by activating or normalizing disabled immune cells. In recent years, researchers have found that many types of PTM are involved in the process of proliferation, activation and metabolic reprogramming of immune cells in cancer microenvironment, and may affect the efficacy of cancer immunotherapy. Therefore, this article reviews the effects of several different PTMs on immune cells in cancer microenvironment, and aims to provide new ideas for cancer immunotherapy.
