1972年,Gery等学者观察到,在人类外周血单个核细胞和小鼠脾细胞的培养上清中存在的一种生物学活性因子,具有刺激胸腺细胞增生的作用。作者把这一因子称为淋巴细胞激活因子(Lymphocyte Activa-ting Factor,简称LAF)。其后,一些实验室还先后报告了发现与LAF的分子量和作用“类似”的一些“其他因子”,并根据被
In 1972, Gery et al. Observed that a biologically active factor present in the culture supernatants of human peripheral blood mononuclear cells and mouse splenocytes has the effect of stimulating thymocyte proliferation. The authors call this factor Lymphocyte Activa-ting Factor (LAF). Since then, some laboratories have also reported on the discovery of some “other factors” that are “similar” to the molecular weight and effect of LAF
