T淋巴细胞生长因子(TCGF)能促进T细胞增殖,还能在体外培养中保持T细胞的特性,因此,TCGF在免疫反应中起着重要作用。本文对TCGF的产生及其机理、活性测定方法、理化特性、生物活性、反应细胞和在临床上的意义简要介绍。 T lymphocyte growth factor (TCGF) can promote T cell proliferation, but also maintain the characteristics of T cells in vitro culture, therefore, TCGF plays an important role in the immune response. In this paper, the generation of TCGF and its mechanism, activity determination methods, physical and chemical properties, biological activity, reactive cells and the clinical significance of a brief introduction.
