IL-3是由T 细胞分泌的可溶性因子,对造血前体细胞具有广谱的促进生长和分化功能。现报道利用人类重组IL-3,进一步研究IL-3促进B 细胞生长、分化的机制结果表明,IL-3是一个B 细胞生长因子。IL-3能刺激经SAC 活化的B 细胞增殖,这种刺激作用与IL-3剂量成正比,并且可
IL-3 is a soluble factor secreted by T cells and has a broad spectrum of promoting growth and differentiation functions for hematopoietic progenitor cells. The use of human recombinant IL-3 to further study the mechanism of IL-3 promoting B cell growth and differentiation revealed that IL-3 is a B cell growth factor. IL-3 stimulates the proliferation of SAC-activated B cells, which is proportional to the dose of IL-3 and can be
