本文讨论白细胞间介素-3(Interleukin-3,IL-3)的生物学和生化学特性。IL-3的许多特性与IL-2类似,两者都促进分化并为各种淋巴细胞系生长所必需。不过,IL-3与IL-2不同之处是,前者主要影响不成熟淋巴细胞分化阶段,因而可以从一个特殊角度来对淋巴细胞分化进行体外研究。20αSDH与T细胞系的关系除了可用各种细胞膜表面抗原鉴定不同淋巴细胞亚群外,还有两种酶已用于鉴定两
This article discusses the biological and biochemical properties of interleukin-3 (IL-3). Many of the properties of IL-3 are similar to those of IL-2, both of which promote differentiation and are essential for the growth of a variety of lymphoid lines. However, the difference between IL-3 and IL-2 is that the former mainly affects the stage of immature lymphocyte differentiation, so that lymphocyte differentiation can be studied in vitro from a special point of view. 20αSDH in Relation to T Cell Lines In addition to identifying different lymphocyte subsets with various cell membrane surface antigens, two more enzymes have been used to identify two
