Abstract

Follicular helper T cells (Tfh) have been referred as a lineage that provides a help for B cells to proliferate and undergo antibody affinity maturation in the germinal center. Evidence has supported that Tfh subset development, like other lineages, is dependent on microenvironment where a particular transcriptional program is initiated. It has been shown that Bcl-6 and IL-21 act as master regulators for the development and function of Tfh cells. Tfh dysregulation is involved in the development of autoimmune pathologies, such as systemic lupus erythematosus, rheumatoid arthritis and other autoimmune diseases. The present review highlights the recent advances in the field of Tfh cells and focus on their development and function.

摘要

滤泡辅助 T 细胞(Tfh)被认为是为 B 细胞提供帮助,使其在生发中心增殖并进行抗体亲和力成熟的谱系。有证据表明,与其他谱系一样,Tfh 亚群的发育依赖于启动特定转录程序的微环境。已经表明,Bcl-6 和 IL-21 作为 Tfh 细胞发育和功能的主调节因子发挥作用。Tfh 失调与自身免疫性疾病的发展有关,如系统性红斑狼疮、类风湿关节炎和其他自身免疫性疾病。本综述强调了 Tfh 细胞领域的最新进展,并重点介绍了它们的发育和功能。
