Costimulatory and inhibitory receptors play a key role in regulating immune responses to infections. Recent translation of knowledge about inhibitory receptors such as CTLA-4 and PD-1 into the cancer clinic highlights the opportunities to manipulate these pathways to treat human disease. Studies in infectious disease have provided key insights into the specific roles of these pathways and the effects of their manipulation. Here, recent studies are discussed that have addressed how major inhibitory and costimulatory pathways play a role in regulating immune responses during acute and chronic infections. Mechanistic insights from studies of infectious disease provide opportunities to further expand our toolkit to treat cancer and chronic infections in the clinic.
共刺激和抑制性受体在调节对感染的免疫反应中起关键作用。最近,诸如CTLA-4和PD-1等抑制性受体的相关知识被转化应用于癌症临床治疗,这凸显了通过操控这些信号通路来治疗人类疾病的可能性。传染病研究为这些信号通路的具体作用及其操控效果提供了关键见解。本文将讨论近期的一些研究,这些研究探讨了主要的抑制性和共刺激信号通路在急性和慢性感染过程中如何调节免疫反应。传染病研究中的机制性见解为进一步扩充我们在临床治疗癌症和慢性感染的手段提供了机会。
