Polysaccharides from Chinese Herbal Lycium barbarum Induced Systemic and Local Immune Responses in H22 Tumor-Bearing Mice

Figure 4

LBP treatment inhibited the production of TGF-β1 and IL-10 in H22 tumor-bearing mice. Effects of LBP on the production of TGF-β1 and IL-10 in the serum of the mice and culture supernatants of H22 cells and RAW264.7 macrophages were investigated by ELISA kits. (a) The level of TGF-β1 in serum. (b) The level of IL-10 in serum. (c) Effect of LBP on TGF-β1 production in H22 cells. (d) Effect of LBP on IL-10 production in RAW264.7 macrophages. Data are represented as mean ± SD, in each group of the mice, in each group of the cells. and versus model group in mice; and versus control group in the cells. ELISA: enzyme-linked immunosorbent assay.
