人类的 T 淋巴细胞群在体外可表现多种功能,包括对可溶性的和细胞表面抗原的增殖反应,释放介质,被多克隆促有丝分裂素所激活以及细胞毒活力等。利用 Ly 表型曾证明小鼠体内存在功能不同的 T 细胞亚类,用异种抗血清也曾证明人 T 细胞的亚类。本文报告重症幼年型类风湿关节炎(JRA)患儿血清中含有某种抗体,它能与 T 细胞亚类 Human T lymphocyte populations can perform a variety of functions in vitro, including proliferative responses to soluble and cell surface antigens, release mediators, activation by polyclonal mitogens, and cytotoxic activity. The use of the Ly phenotype has demonstrated the presence of functionally distinct subsets of T-cells in mice, as well as subclasses of human T cells demonstrated using heterogeneous antisera. This article reports severe juvenile rheumatoid arthritis (JRA) serum containing some antibodies, it can be T cell subsets
