摘 要:采用人重组白细胞介素4(IL-4)观察了对瘤细胞系的生物调节作用,包括对细胞增殖、分化、表面标志表达及细胞因子分泌的影响。9株不同类型的瘤细胞系对IL-4的增殖反应不同,即4/9抑制,3/9促进,2/9无影响。IL-4抑制U937的增殖与其促进细胞分化作用有关。对某些细胞系,IL-4能增强MHCI类、Ⅱ类及肿瘤相关抗原的表达。IL-4尚能抑制MLA144的IL-2分泌。初步结果表明,IL-4对瘤细胞有多种生物功能,其调节作用因瘤细胞类型及功能状态的不同而异。The effect of IL-4 on biological regulation of tumor cell lines was observed by using hu-man recombinant interleukin-4.The observation included cell proliferation, differentiation,cell surface marker and cytokine secretion. The effect of IL-4 on cell proliferation of nine celllines was different.It showed 4/9 inhibitory effect,3/9 enhancing effect and 2/9 no effect.The inhibitory effect of IL-4 on U937 cell proliferation was correlated with cell differentia-tion.IL-4 enhanced the expression of cell surface markers(including MHC class I, MHCclass Ⅱ and TAA)of some cell lines. Furthermore,IL-4 inhibited the production of IL-2 byMLA144.The preliminary results indicate that the effect of IL-4 on biological regulation oftumor cell lines is benefitial for controlling tumor cell growth and enhancing tumor cellrecognition by effector cells,However,the down regulation also could be exerted.
