CD4 T 细胞在防止多种真菌感染方面发挥着重要且非冗余的作用。不同的 CD4 T 细胞亚群可以介导针对真菌疾病的保护,其中 Th1 和 Th17 CD4 T 细胞亚群被发现可以促进真菌清除和针对多种真菌病原体的保护性免疫。幼稚 CD4 T 细胞分化为 Th1 或 Th17 细胞的关键是它们与树突状细胞的相互作用,并受到细胞因子的指导。 IL-12和IFN-γ促进Th1分化,而TGF-β、IL-6、IL-1、IL-21和IL-23促进Th17分化和维持。 DC 产生的这些细胞因子反过来又受到响应真菌感染而触发的先天受体的调节。在这篇综述中,我们将讨论细胞因子对影响真菌特异性 CD4 T 细胞分化的贡献及其在防御真菌疾病中的作用。我们还将强调先天受体在识别真菌方面的贡献以及它们如何影响细胞因子分泌和 CD4 T 细胞分化。
CD4 T cells play important and non-redundant roles in protection against infection with diverse fungi. Distinct CD4 T cell subsets can mediate protection against fungal disease where Th1 and Th17 CD4 T cell subsets have been found to promote fungal clearance and protective immunity against diverse fungal pathogens. The differentiation of naïve CD4 T cells into Th1 or Th17 cells is crucially controlled by their interaction with dendritic cells and instructed by cytokines. IL-12 and IFN-γ promote Th1 differentiation while TGF-β, IL-6, IL-1, IL-21 and IL-23 promote Th17 differentiation and maintenance. The production of these cytokines by DCs is in turn regulated by innate receptors triggered in response to fungal infection. In this review we will discuss the contributions of cytokines found to influence fungus-specific CD4 T cell differentiation and their role in defense against fungal disease. We will also highlight the contributions of innate receptors involved in recognition of fungi and how they shape cytokine secretion and CD4 T cell differentiation.
