In this issue, Fang et al. (https://doi.org/10.1084/jem.20180927) report on a subset of T follicular helper (Tfh) cells that transiently expresses T-bet yet continues to produce IFN-γ at late stages of GC reactions following immunization. They find other genes uniquely expressed in this IFN-γ-producing Tfh subset, such as NKG2D, that can be used to better distinguish these functionally distinct Tfh cells.
在本期杂志中,Fang 等人(https://doi.org/10.1084/jem.20180927)报道了一类短暂表达 T 细胞因子(T-bet)但在免疫后 GC 反应晚期仍持续产生 IFN-γ的滤泡辅助性 T 细胞(Tfh)亚群。他们发现了在这种产生 IFN-γ 的 Tfh 亚群中独特表达的其他基因,如 NKG2D,这些基因可用于更好地区分这些功能不同的 Tfh 细胞。
