摘要: A族β溶血性链球菌(GAS)是儿童常见感染病原,其引起的扁桃体炎性反应反复发作,即为复发性A族链球菌性扁桃体炎(GAS-RT)。新近研究认为,GAS-RT并非传统意义上的感染性疾病,而是一种免疫敏感性疾病,经由超抗原(SAgs)和生发中心(GC)的滤泡辅助T细胞(Tfh)相互作用,发挥对GC的B细胞细胞毒作用来逃避免疫应答,该理论为临床提供了新的免疫靶向治疗的思路。

Abstract: Group A beta-hemolytic Streptococcus (GAS) is a common infectious agent in children which may cause recurrent inflammation of the tonsils, known as recurrent group A Streptococcus tonsillitis (GAS-RT). Recent studies found that GAS-RT is not an infectious disease as traditional sense, but rather than an immunosensitive disease that evades the immune response through the interaction between superantigens (SAgs) and follicular helper T cells (Tfh) in the germinal center (GC), which exerts a cytotoxic effects on B cells in the GC. This theory suggested a potential new strategy for clinical treatement.

Key words: recurrent tonsillitis, immune mechanism, Streptococcus pyrogenic exotoxins A, T follicular helper cells, bacteriotherapy
