摘要:

文题释义:
重组人干扰素α-2b:是一种人工合成的低分子蛋白质,由164个氨基酸构成的多肽,是第一个克隆化生产并广泛应用于临床治疗的细胞因子,具有抗病毒、抗增殖活性、抗肿瘤、免疫调节等多种功能活性。
增生性瘢痕:组织过度增生形成的一种病理性瘢痕,表现为创面局部异常增生高出于皮面的红色瘢痕组织。其病理特征主要表现为肌成纤维细胞的过度增殖及细胞外基质尤其是胶原的过度沉积。

背景:重组人干扰素α-2b是具有抗病毒、抗增殖活性、抗肿瘤、免疫调节等功能活性的细胞因子,对瘢痕组织具有一定的预防及治疗作用。
目的:探索重组人干扰素α-2b作用于瘢痕成纤维细胞的效果,观察其对瘢痕成纤维细胞增殖及迁移能力的影响。
方法:体外培养瘢痕成纤维细胞至对数增长期,采用0,5 000,10 000,20 000 IU/mL重组人干扰素α-2b处理48 h,通过EdU染色观察细胞增殖能力,采用划痕实验及Transwell实验检测细胞迁移能力的改变,免疫印迹法检测增殖及迁移相关蛋白增殖细胞核抗原、基质金属蛋白酶2的表达水平。
结果与结论:①体外细胞实验观察结果显示,同空白对照组比较,重组人干扰素α-2b处理组可明显降低EdU增殖阳性细胞数,且细胞划痕愈合率和细胞迁移数目显著下降(P < 0.05),瘢痕成纤维细胞增殖相关蛋白增殖细胞核抗原和迁移相关蛋白基质金属蛋白酶2的蛋白表达水平也明显下降(P < 0.05);②结果证实,重组人干扰素α-2b具有抑制瘢痕成纤维细胞增殖、降低细胞迁移率的作用。

Abstract: BACKGROUND: Recombinant human interferon α-2b is a cytokine with antiviral, antiproliferative, antitumor, and immunomodulatory activities, which has certain preventive and curative effects on scar tissue.  
OBJECTIVE: To explore the effects of recombinant human interferon α-2b on scar fibroblasts and to observe its effects on the proliferation and migration abilities of scar fibroblasts.  
METHODS: In vitro scar fibroblasts were cultured to logarithmic growth phase and treated with 0, 5 000, 10 000, 20 000 IU/mL recombinant human interferon α-2b for 48 hours. Cell proliferation was observed by EdU staining and cell migration was detected through cell scratch test and Transwell test. Expression levels of proliferating cell nuclear antigen and matrix metalloproteinase 2, proliferation- and migration-associated proteins of scar fibroblasts were detected by western blot assay.  
RESULTS AND CONCLUSION: The results of in vitro cell experiments showed that, compared with the control group, recombinant human interferon α-2b could significantly decrease the number of EdU-positive cells, the wound healing rate, the number of migrated cells, and the protein levels of proliferating cell nuclear antigen and matrix metalloproteinase 2 (P < 0.05). All these findings indicate that recombinant human interferon α-2b can inhibit the proliferation and migration of scar fibroblasts.

Key words: recombinant human interferon α-2b, hypertrophic scar, fibroblast, cell migration
