IL4 and non-small cell lung carcinoma: (153) used intradermal injection of autologous DCs combined with intravenous infusion of ginseng polysaccharide (GPS) to treat 96 patients with non-small cell lung cancer, and found that Th1 (INF-γ, IL-2) and Th1/Th2 (INF-γ/IL-4, IL-2/IL-5) were higher than the control in the study group and lower than the control group in the Th2 (IL-4, IL-5) after the treatment, which indicated that GPS was able to maintain the dynamic balance of Th1/Th2.
