CD 8 T细胞的参与是对病原体的免疫应答和肿瘤监测的关键方面。尽管如此,大多数使用普通佐剂的疫苗接种策略未能引发长期记忆性CD 8 T细胞。对CD 8 T细胞活化的细胞和分子要求的了解增加,揭示了直接调节CD 8 T细胞以产生最佳应答的新机会。在慢性感染和癌症期间,增强T细胞应答的免疫调节策略对于克服免疫抑制微环境可能是特别必要的。在这篇综述中,我们将讨论抑制性受体的阻断;白细胞介素-2的管理;调节性T细胞的调节;和靶向的mTOR,作为手段,以提高CD 8 T细胞免疫。
Engagement of CD8 T cells is a crucial aspect of immune responses to pathogens and in tumor surveillance. Nonetheless most vaccination strategies with common adjuvants fail to elicit long-term memory CD8 T cells. Increased knowledge on the cellular and molecular requirements for CD8 T cell activation have unveiled new opportunities to directly modulate CD8 T cells to generate optimal responses. During chronic infections and cancer, immunomodulation strategies to enhance T cell responses may be particularly necessary to overcome the immunosuppressive microenvironment. In this review we will discuss blockade of inhibitory receptors; interleukin-2 administration; regulatory T cell modulation; and targeting of mTOR, as means to enhance CD8 T cell immunity.
