摘要:

背景:植物凝集素可以刺激外周血单个核细胞分裂并引起免疫细胞的活化,是常用的细胞增殖模型。但是全血中的非外周血单个核细胞成分(血浆和无核细胞)在植物凝集素参与的体外培养过程中起到什么作用,以及内皮分泌因子的表达情况尚不明确。

目的:在体外单独培养或全血培养外周血单个核细胞过程中,观察植物凝集素对其增殖和凋亡的影响,以及相关炎症因子以及内皮分泌因子的表达变化。
方法:分离正常核型成人的外周血单个核细胞,应用无植物凝集素培养基和加入植物凝集素培养基分别进行单独培养,观察细胞形态学变化。收集全血培养或不同条件单独培养的外周血单个核细胞,提取mRNA,荧光定量RT-PCR检测细胞增殖、凋亡,以及炎症因子和内皮分泌因子的表达变化,并进行统计学分析。

结果与结论:外周血单个核细胞单独培养和全血培养存在差异,植物凝集素会促进外周血单个核细胞 Ki67、增殖细胞核抗原、蛋白水解酶3、γ-干扰素、肿瘤坏死因子β和白细胞介素6的基因表达,抑制蛋白 C表达。提示植物凝集素促进体外培养外周血单个核细胞的增殖及凋亡,促使炎症因子表达上调,部分血液生物学相关的内皮分泌因子下调。

Abstract:

BACKGROUND: Phytohemagglutinin (PHA) can stimulate the peripheral blood mononuclear cells (PBMCs) into cell cycle, and cause their immune activation, which is a common immune proliferation model. However, the role of non-PBMC ingredient of peripheral blood is unclear, as well as the expression of endothelial cells related cytokines.

OBJECTIVE: To study the effect of whole blood culture and PBMCs alone culture with PHA on the PBMC proliferation and apoptosis, expression of inflammatory cytokine and endothelial cell secreted cytokine markers.
METHODS: Morphological changes of PBMCs separated from normal karyotype human peripheral blood individually cultured with or without PHA were observed. The PBMCs were collected by whole blood culture or PBMC separated culture. mRNA was extracted for the fluorescence quantitative RT-PCR, which was applied to detect the cell proliferation, apoptosis, and expression of inflammatory cytokine and endothelial cell secreted cytokines. The statistic analysis was used for the significance explication.

RESULTS AND CONCLUSION: PBMCs alone cultured ere different from those undergoing whole blood culture. The PHA could up-regulate the gene expression of Ki67, proliferating cell nuclear antigen, Caspase 3, interferon-γ, tumor necrosis factor-β and interleukin-6, but down-regulate Protein C. This indicted that PHA could promote the proliferation and apoptosis of PBMCs and up-regulate the expression of inflammatory cytokines, but down-regulate the expression of endothelial cells secreted coagulation cytokines.
