康艾注射液对人结直肠癌Lovo细胞Th1/Th2类细胞因子的影响

Objective To explore the effect of Kang'ai injection on Th1/Th2 cytokine in human colon carcinoma cell line Lovo.Methods Lovo cells were cultured by conventional ways until they were in exponential growth phase and then divided into 4 groups:one control group and three experimental groups with different concentration of Kang'ai injection.After 72 hours culture,Th1 type cytokines (IL-2,IFN-γ) and Th2.type cytokines (IL-4,IL-10) in the culture supernatant of Lovo cells in each group were separately detected by double-antibody sandwich enzyme-linked immunosorhent assay (ELISA).Results After the coculture of Lovo cells and Kang'ai injection,Th2 type cytokine levels in the supernatants were significant lower than the control group (P＜0.05),and Th1 type cytokines in each group were of little change.Conclusions Kang'ai injection markedly downregulated Th2 type cytokines in Lovo cells,and contributed to the switching from Th2 to Th1.
