摘要: 初步探讨新疆栽培一枝蒿未除蛋白的粗多糖(Un-deproteinization of cultivated Artemisia rupestris L. crude polysaccharides,UCARCP)对模式抗原卵清白蛋白(Ovalbumin,OVA)免疫小鼠后抗体水平以及T淋巴细胞亚群的影响。将UCARCP配伍OVA皮下免疫小鼠,初免1次,加强1次,铝佐剂为阳性对照组,间接ELISA法检测小鼠血清中IgG及亚类IgG1、IgG2a的抗体水平;流式细胞术检测脾细胞中CD3+CD4+和CD3+CD8+T淋巴细胞亚群的含量。结果显示,UCARCP能显著提高小鼠血清中IgG、IgG1、IgG2a的抗体水平(P<0.05),且与铝佐剂组相比无显著性差异(P>0.05);UCARCP能显著促进CD3+CD4+和CD3+CD8+ T细胞亚群的含量(P<0.05),与铝佐剂组相比没有显著差异(P>0.05)。新疆栽培一枝蒿未除蛋白的粗多糖能显著促进模式抗原OVA免疫后小鼠的体液免疫水平和细胞免疫水平,与铝佐剂相当。

Abstract: This work aims to investigate the effect of un-deproteinized crude polysaccharides(UCARCP)from cultivated Artemisia rupestris L. on antibody level and T lymphocyte subsets in mice immunized ovalbumin(OVA)antigen. Mice were immunized subcutaneously with OVA formulated with UCARCP,priming one time,boosting one time,and aluminum adjuvant for the positive control group. Indirect ELISA assay was performed to evaluate IgG antibody levels,and CD3+CD4+and CD3+CD8+T lymphocyte subsets in splenocytes were determined by flow cytometry. As results,UCARCP significantly increased the antibody levels of IgG,IgG1 and IgG2a in mice serum(P < 0.05);and in contrast to aluminum adjuvant group,there was no significant difference(P > 0.05). Moreover,UCARCP obviously enhanced the percentages of CD3+CD4+ and CD3+CD8+T cells(P < 0.05),and there was also no significant difference compared with that in aluminum adjuvant group(P >0.05). In conclusion,UCARCP can significantly enhance the humoral and cellular immunity in mice immunized with OVA,and it has the same effects with aluminum adjuvant.
