IL-3和IL-5是参与造血过程及免疫系统调节的一类糖蛋白激素,两者在辅助性T细胞克隆中可协调地表达,并且具有广泛的生物学作用。Ihle等人利用小鼠-中国仓鼠杂交体已将IL-3基因定位于第11号染色体上,作者最近也用同样的方法将IL-5基 IL-3 and IL-5 are a class of glycoprotein hormones involved in the process of hematopoiesis and immune system regulation, both of which can be coordinatedly expressed in helper T cell clones and have a wide range of biological roles. Ihle et al. Have used the mouse-Chinese hamster hybrid to map the IL-3 gene on chromosome 11 and the authors recently used the same method to separate IL-5
