Abstract

Immune checkpoints are cell surface molecules that initiate regulatory pathways which have powerful control of CD8 cytolytic T cell activity. Antagonistic and agonistic antibodies engaging these molecules have demonstrated profound impact on immune activation and have entered clinical use for the treatment of a variety of diseases. Over the past decade, antagonistic antibodies known as immune checkpoint inhibitors have become a new pillar of cancer treatment and have reshaped the therapeutic landscape in oncology. These agents differ in their mechanism of action and toxicity profiles compared to more traditional systemic cancer treatments such as chemo- and targeted therapies. This article reviews the pharmacology of this new class of agents.

摘要

免疫检查点是细胞表面分子,可启动对 CD8 细胞毒性 T 细胞活性具有强大控制作用的调节途径。与这些分子结合的拮抗性和激动性抗体已证明对免疫激活具有深远影响,并已用于治疗各种疾病。在过去十年中,被称为免疫检查点抑制剂的拮抗性抗体已成为癌症治疗的新支柱,并重塑了肿瘤学的治疗格局。与更传统的全身癌症治疗(如化疗和靶向治疗)相比,这些药物在作用机制和毒性特征方面有所不同。本文综述了这一类新型药物的药理学。
