摘要

III型固有淋巴细胞(group 3 innate lymphoid cells, ILC3)是近十年才被定义的一群新型免疫细胞,属于固有淋巴细胞家族。ILC3包括多种表型和功能差异的细胞亚群,主要分布于肠道、肺及皮肤等屏障组织,在机体免疫调节、组织修复和淋巴组织形成中起重要作用。然而,在多种炎症性疾病中,ILC3出现数量和功能异常,可通过分泌白介素(interleukin, IL)-17、IL-22、γ-干扰素(interferon γ, IFN-γ)及粒-巨噬细胞集落刺激因子(granulocyte-macrophage colony-stimulating factor, GM-CSF)等致炎性细胞因子调控其他免疫细胞和诱导异位淋巴结构形成,从而促进疾病的发生和进展。因此,深入探究ILC3的表型及功能对拓展炎症性疾病的认识和寻找新的治疗靶点具有重要意义。本文就ILC3的表型特点、生物学功能及其在炎症性疾病中的研究进展进行综述。

Abstract

Group 3 innate lymphoid cells (ILC3) as a family member of innate lymphoid cells (ILCs), have been defined as novel innate immune cells in the past decade. ILC3 include a variety of heterogenous subsets with different phenotypes and functions, which are mainly distributed in barrier organs such as the intestine, lung and skin. They play an important role in immune regulation, tissue repair and lymphoid tissue formation. However, in various inflammatory diseases, ILC3 become dysregulated and participate in the pathogenesis through secreting a series of cytokines such as interleukin (IL)-17, IL-22, interferon-γ (IFN-γ) and granulocyte-macrophage colony-stimulating factor (GM-CSF) to modulate other immune cells and induce the formation of ectopic lymphoid structures. Therefore, it is of great significance to explore the phenotype and function of ILC3 in order to advance the understanding of inflammatory diseases and find new therapeutic targets. In this article, the phenotypic characteristics, biological functions and research progress of ILC3 in inflammatory diseases were reviewed.
