The type 2 immune response is critical for host defense against large parasites such as helminths. On the other hand, dysregulation of the type 2 immune response may cause immunopathological conditions, including asthma, atopic dermatitis, rhinitis, and anaphylaxis. Thus, a balanced type 2 immune response must be achieved to mount effective protection against invading pathogens while avoiding immunopathology. The classical model of type 2 immunity mainly involves the differentiation of type 2 T helper (Th2) cells and the production of distinct type 2 cytokines, including interleukin-4 (IL-4), IL-5, and IL-13. Group 2 innate lymphoid cells (ILC2s) were recently recognized as another important source of type 2 cytokines. Although eosinophils, mast cells, and basophils can also express type 2 cytokines and participate in type 2 immune responses to various degrees, the production of type 2 cytokines by the lymphoid lineages, Th2 cells, and ILC2s in particular is the central event during the type 2 immune response. In this review, we discuss recent advances in our understanding of how ILC2s and Th2 cells orchestrate type 2 immune responses through direct and indirect interactions.

在塑造2型免疫反应中ILC2和Th2细胞之间的编排。

2型免疫反应对于宿主防御大型寄生虫(例如蠕虫)至关重要。另一方面,2型免疫反应异常可能引起免疫病理状况,包括哮喘,特应性皮炎,鼻炎和过敏反应。因此,必须实现平衡的2型免疫应答,以有效防御入侵的病原体,同时避免免疫病理。2型免疫的经典模型主要涉及2型T辅助(Th2)细胞的分化和独特的2型细胞因子的产生,包括白介素4(IL-4),IL-5和IL-13。最近,第2组先天性淋巴样细胞(ILC2)被认为是2型细胞因子的另一个重要来源。尽管嗜酸性粒细胞,肥大细胞,嗜碱性粒细胞也可以表达2型细胞因子并在不同程度上参与2型免疫反应,尤其是淋巴谱系,Th2细胞和ILC2产生2型细胞因子是2型免疫反应过程中的中心事件。在这篇综述中,我们讨论了对ILC2s和Th2细胞如何通过直接和间接相互作用来协调2型免疫应答的理解的最新进展。
