摘要:

文题释义:
骨髓源性巨噬细胞:人骨髓来源巨噬细胞分离自骨髓,骨髓细胞中存在未分化的巨噬细胞前体,通过加入巨噬细胞集落刺激因子来分化培养出巨噬细胞。巨噬细胞属免疫细胞,有多种功能,是研究细胞吞噬、细胞免疫和分子免疫学的重要对象。巨噬细胞属不繁殖细胞群,在适宜条件下可生活两三周,多用做原代培养,难以长期生存。
吞噬作用:高等动物具有一些特化的吞噬细胞,包括巨噬细胞和中性粒细胞。它们通过吞噬菌体摄取和消灭感染的细菌、病毒、损伤的细胞、衰老的红细胞。吞噬作用是生物体最古老的,也是最基本的防卫机制之一。对于其要消灭的对象无特异性,在免疫学中称之为非特异性免疫作用。

背景:经典激活巨噬细胞和替代激活巨噬细胞具有不同的表型和功能,目前尚鲜有研究探讨不同诱导方式对骨髓来源巨噬细胞生物学功能的影响。
目的:探讨不同诱导极化方式对大鼠骨髓来源巨噬细胞生物学行为的影响。
方法:通过原代细胞形态学观察、瑞氏染色和流式细胞术对体外分离培养的大鼠骨髓来源巨噬细胞进行鉴定。经γ-干扰素和脂多糖、白细胞介素4分别诱导激活24 h,倒置显微镜观察细胞形态,Real time-PCR检测细胞表面标记物Nos2和Arg1的表达,CCK-8法检测细胞增殖能力,流式细胞术检测细胞凋亡水平,中性红染色鉴定细胞吞噬功能。
结果与结论:经γ-干扰素和脂多糖联合刺激的骨髓来源巨噬细胞高表达M1型细胞表面标记物Nos2,可促进细胞凋亡并且降低细胞的吞噬功能;而经白细胞介素4刺激的骨髓来源巨噬细胞则高表达M2型细胞表面标记物Arg1,提高细胞增殖和吞噬能力,抑制细胞凋亡。结果表明,不同诱导极化方式可影响骨髓来源巨噬细胞的生物学行为。

Abstract: BACKGROUND: Classically activated and alternative activated macrophages have different phenotypes and functions, and there are few studies to explore the effect of different induction methods on the biological functions of bone marrow-derived macrophages. 
OBJECTIVE: To explore the effect of different induced polarization ways on biological behaviors of bone marrow-derived macrophages from rats.
METHODS:  Rat bone marrow-derived macrophages were isolated and cultured in vitro, and identified by morphological observation, Wright Giemsa staining and flow cytometry. After being induced and activated by interferon-γ, lipopolysaccharide and interleukin-4 for 24 hours, the morphology of bone marrow-derived macrophages was observed by inverted microscope. The expression levels of cell surface markers Nos2 and Arg1 were detected by real time-PCR. CCK8 assay was performed to determine the proliferation ability of bone marrow-derived macrophages. Flow cytometry was performed to detect the apoptosis, and neutral red staining was performed to identify the phagocytic function of bone marrow-derived macrophages.    
RESULTS AND CONCLUSION: Bone marrow-derived macrophages that stimulated by interferon-γ and lipopolysaccharide were highly expressing the cell surface marker Nos2 of M1, and apoptosis of bone marrow-derived macrophages can be slightly promoted as well as the phagocytic function of bone marrow-derived macrophages is reduced; while bone marrow-derived macrophages stimulated by interleukin-4 are highly expressing the cell surface marker Arg1 of M2. Cell proliferation and phagocytosis of bone marrow-derived macrophages are promoted, and apoptosis of bone marrow-derived macrophages is inhibited. The results confirm that the biological behavior of bone marrow-derived macrophages can be affected by different methods of induced polarization.
