基于 CD8⁺ T 细胞的癌症免疫治疗

The immune system in humans is a defense department against both exogenous and endogenous hazards, where CD8 + T cells play a crucial role in opposing pathological threats. Various immunotherapies based on CD8 + T cells have emerged in recent decades, showing their promising results in treating intractable diseases.

However, in the fight against the constantly changing and evolving cancers, the formation and function of CD8 + T cells can be challenged by tumors that might train a group of accomplices to resist the T cell killing. As cancer therapy stepped into the era of immunotherapy, understanding the physiological role of CD8 + T cells, studying the machinery of tumor immune escape, and thereby formulating different therapeutic strategies become the imperative missions for clinical and translational researchers to fulfill.

After brief basics of CD8 + T cell-based biology is covered, this review delineates the mechanisms of tumor immune escape and discusses different cancer immunotherapy regimens with their own advantages and setbacks, embracing challenges and perspectives in near future.
