ABSTRACT
Natural Killer （NK） cells are another type of anti-tumor immune cells with promising clinical application in addition to T cells. NK cell activity is mainly regulated by its surface receptors and immune microenvironment. The strong immunosuppressive microenvironment of glioma results in low efficiency of NK cell immunotherapy. This article reviews NK cells in the immunotherapy for glioma from the interaction of glioma-NK cell， and the latest research progress of targeted NK cells compounds， monoclonal antibody， and cytokine therapy， focusing on the genetic modification of NK cells in the present situation and trend of glioma immunotherapy， and molecular mechanism of glioma cells related to immune escape. We hope this article will provide theoretical basis and new ideas for NK cell-based immunotherapy of glioma.
ABSTRACT
<p><b>OBJECTIVE</b>To study the effects of Arbuscular Mycorrhizae on cultivated Atractylodes lancea.</p><p><b>METHOD</b>Pot experiment of A. lancea, with (code as AM) or without (code as CK) Glomus mosseae (GM) was conducted 5 times respectively, then the biomass, essential oil, and soil nutrition, soil organism, soil microbial were detected after A. lancea were harvested.</p><p><b>RESULT</b>(1) Mycorrhizal dependency of A. lancea was 245%, and height of individuals, numbers of leaves, leaf area, biomass of A. lancea were all higher in AM than in CK (P < 0.05). (2) GC-MS analysis with cluster analysis and principal components analysis showed that there were no differences in essential oil of A. lancea between AM and CK. (T3) Total N, available N, available P and available K in AM soil were all lower than in CK soil. (4) GC-MS analysis showed organic matters changed differenly in AM soil and CK soil, components 5,6 in AM soil were higher than that in CK soil, but component 9, 10, 11 were lower in AM soil than that in CK soil. (5) Biolog detect showed AWCD of AM soil microbe were higher than that of CK soil throughout the incubation, and AWCD of the former was 0.66, and the later was 0.46 after 192 h incubation. and t-test showed, Shannon seven indices and McIntosh'seven indices were same both at 72 h and 192 h, and diversity indices of Shannon and McIntosh were also same at 72 h, but AM soil microbe were higher than CK soil microbe at 168 h (P < 0.05).</p><p><b>CONCLUSION</b>AM could promote nutrition uptake, improve the function diversity and activity of microbe in rhizosphere of A. lancea, influence the composition of the organic matter, that lead the growth of A. lancea, but not to the quality.</p>
