γδ T 细胞在小鼠和人类的体内平衡和传染病和肿瘤等疾病中发挥着关键作用。它们可分为两个主要功能亚群:产生 IFN-γ 的 γδT1 细胞和产生 IL-17 的 γδT17 细胞。虽然 CD27 表达在小鼠中区分了这两个亚群,但我们对人类 γδT17 细胞的分化和扩增知之甚少。先前的研究已经在人类皮肤和粘膜组织(包括口腔和结肠)中发现了 γδT17 细胞。然而,来自外周血单核细胞 (PBMC) 的人 γδ T 细胞主要产生 IFN-γ。在本协议中,我们描述了一种从 PBMC 中体外扩增和极化人类 γδT17 细胞的方法。 主要特点 • 从外周血单核细胞扩增 γδ T 细胞。 • 使用IL-7 和抗γδTCR 进行人IL-17A 产生的γδ T 细胞分化和扩增。 • γδ T 细胞扩增后IL-17A 产生的分析。该协议用于:科学进展(2022),DOI:10.1126/sciadv.abm9120
γδ T cells play a critical role in homeostasis and diseases such as infectious diseases and tumors in both mice and humans. They can be categorized into two main functional subsets: IFN-γ-producing γδT1 cells and IL-17-producing γδT17 cells. While CD27 expression segregates these two subsets in mice, little is known about human γδT17 cell differentiation and expansion. Previous studies have identified γδT17 cells in human skin and mucosal tissues, including the oral cavity and colon. However, human γδ T cells from peripheral blood mononuclear cells (PBMCs) primarily produce IFN-γ. In this protocol, we describe a method for in vitro expansion and polarization of human γδT17 cells from PBMCs. Key Features • Expansion of γδ T cells from peripheral blood mononuclear cells. • Human IL-17A-producing γδ T-cell differentiation and expansion using IL-7 and anti-γδTCR. • Analysis of IL-17A production post γδ T-cell expansion.
