The immune system can recognize tumor cells to mount antigen-specific T cell response. Central to the establishment of T cell-mediated adaptive immunity are the inflammatory events that facilitate antigen presentation by stimulating the expression of MHC and costimulatory molecules and the secretion of pro-inflammatory cytokines. Such inflammatory events can be triggered upon cytotoxic treatments that induce immunogenic cancer cell death modalities. However, cancers have acquired a plethora of mechanisms to subvert, or to hide from, host-encoded immunosurveillance. Here, we discuss how tumor intrinsic oncogenic factors subvert desirable intratumoral inflammation by suppressing immunogenic cell death.
免疫系统能够识别肿瘤细胞,从而引发针对特定抗原的 T 细胞反应。在建立 T 细胞介导的适应性免疫中,关键的是炎症事件,这些事件通过刺激 MHC 和共刺激分子的表达以及促炎细胞因子的分泌,促进抗原呈递。这种炎症事件可以在诱导免疫原性癌细胞死亡方式的细胞毒性治疗中触发。然而,癌症已经获得了大量的机制来颠覆或逃避宿主编码的免疫监视。在这里,我们讨论了肿瘤内在的致癌因素如何通过抑制免疫原性细胞死亡来抑制理想的肿瘤内炎症。
