Protein Profi ling of CIK Cell and Its Supernatant Detected by Protein Chip Technology

摘要

摘要: 目的应用蛋白芯片技术检测不同患者来源的细胞因子诱导的杀伤细胞（cytokine induced killer, CIK）细胞裂解液和培养上清的蛋白谱改变。方法将3例不同患者来源的人外周血单个核细胞（peripheral blood mononuclear cell, PBMC）在体外经细胞因子诱导成CIK细胞，经流式细胞术测定细胞表型后，分别收集培养第20天的CIK细胞和细胞培养上清，应用AAH-BLM-1蛋白芯片分别获得CIK 细胞裂解液和细胞培养上清中507个蛋白的改变。结果 CIK细胞在培养第20天，CD3+和CD3+CD56+的T细胞分别为（86.43±10.65）％和（38.58±3.94）％。CIK细胞培养上清液中共有6个蛋白明显升高（Signal≥700, FC≥1.8）：MIP-1β (FC=21.28)、GzmA (FC=5.54)、IFN-?(FC=2.78)、MCP-1 (FC=2.22)、TMPO (FC=2.05)、IL-13 (FC=1.81)；细胞裂解液共有8个蛋白明显升高（Signal≥700）：GzmA (Signal=1 968.77)、ET (Signal=1,398.60)、IL-13 (Signal=1 333.47)、TFPI (Signal=959.76)、N R G 3 ( S i g n a l = 9 4 4 . 0 9 ) 、I L -7 ( S i g n a l = 8 6 7 . 1 2 ) 、M I P -1 α ( S i g n a l = 8 3 3 . 4 3 ) 、M I P - 1 β(Signal=704.88)。将上述两组结果对比分析后发现GzmA、IL-13和MIP-1β这3个蛋白在两组中均明显升高。结论 CIK细胞在活化过程中合成并分泌如GzmA、IFN-γ、IL-8和IL-13等间接杀伤肿瘤细胞并促进T细胞增殖活化在抗肿瘤治疗中发挥重要作用。多种蛋白产物，这些蛋白产物通过直/间接杀伤肿瘤细胞并促进T细胞增殖活化在抗肿瘤治疗中发挥重要作用。

Abstract: Objective Protein profi ling was detected both in cells lysates and culture supernatant of cytokine induced killer (CIK) cells from different patients by protein chip technology. Methods The peripheral blood mononuclear cells (PBMC) of 3 tumor patients were stimulated by different cytokines and induced into CIK cells in vitro. The phenotypes of CIK cells were analyzed by fl ow cytometry. CIK cells and culture supernatant was collected respectively after cultured for 20 days. Expression changes of 507 proteins were detected either in cells lysates or in cell culture supernatant by AAH-BLM-1 protein chip technology. Results The percentages of CD3+ and CD3+CD56+ were （86.43±10.65）% and （38.58±3.94）% respectively after CIK cells expanding for 20 days. Six proteins were increased signifi cantly in cell culture supernatant (signal ≥700, FC≥1.8): MIP - 1 β (FC=21.28), GzmA (FC=5.54), IFN- ? (FC=2.78), MCP - 1 (FC=2.22), TMPO (FC=2.05), IL - 13 (FC=1.81). Eight proteins were increased significantly in cells lysates (signal≥700): GzmA (signal=1,968.77), ET (signal=1,398.60), IL - 13 (signal=1,333.47), TFPI (signal=959.76), NRG3 (signal=944.09), IL - 7 (signal=867.12), MIP - 1α (signal=833.43), MIP - 1β (signal=704.88). Three proteins of GzmA, IL-13 and MIP-1β were increased significantly both in two groups. Conclusion CIK cells synthesize and release a variety of protein products during the process of activation, such as GzmA, IFN-γ, IL-8, IL-13, etc. These proteins play important roles of anti-tumor by killing tumor cells directly / indirectly and promoting the proliferation and activation of T cells.
