研究了猪苓多糖（ＰＵＰＳ）与ＩＬ－２协同诱导人外周血单个核细胞（ＰＢＭＣ）成为具有较高杀伤肿瘤活性的细胞，其培养体系总杀伤单位明显高于ＬＡＫ细胞，其诱导细胞的杀伤活性可能与其分泌ＩＦＮ和ＴＮＦ有关，此研究为ＰＵＰＳ与ＩＬ－２协同诱导细胞的进一步研究和临床应用打下了理论基础。
It was studied that PUPS and IL-2 synergistically induce human peripheral blood mononuclear cells (PBMCs) to become highly cytotoxic tumor cells with a higher total killing unit in culture system than those in LAK cells, which induce cell killing Activity may be related to its secretion of IFN and TNF, this study for the PUPS and IL-2 co-induced cells to further study and clinical application of the theory laid the foundation.
