摘要:


文题释义:
金诺芬:是一种有机金化合物,具有抗炎和免疫调节作用。
M1型巨噬细胞:是巨噬细胞的一种极化状态,以分泌促炎细胞因子为特征。在糖尿病伤口愈合过程中,M1型巨噬细胞的持续激活会加剧局部炎症反应,导致伤口延迟愈合。

背景:在糖尿病伤口愈合过程中,M1型巨噬细胞的持续激活加剧了炎症反应,阻碍了伤口愈合。金诺芬作为一种具有抗炎特性的药物,对M1型巨噬细胞的影响及在糖尿病伤口愈合中的潜在作用尚未明确。
目的:探讨不同浓度金诺芬对M1型巨噬细胞生物学功能的影响,并评估金诺芬在糖尿病伤口愈合中的潜在应用价值。
方法:以RAW264.7细胞、THP-1细胞作为研究对象,通过不同浓度的干扰素γ和脂多糖诱导M1型极化。然后,使用1,2 μmol/L金诺芬处理M1型巨噬细胞,采用CCK-8法评估金诺芬对细胞活力的影响,采用qPCR检测白细胞介素1β、白细胞介素6和肿瘤坏死因子α mRNA表达,ELISA法检测细胞上清液中白细胞介素1β、白细胞介素6和肿瘤坏死因子α水平,Western blot检测NF-κB(p65)及磷酸化MAPK(p-MAPK)和总MAPK的蛋白表达。此外,选取6-8周龄雄性C57BL/6J小鼠及db/db糖尿病小鼠,分为C57对照组、db/db对照组和金诺芬治疗组,每组6只,进行背部皮肤缺损造模及腹腔注射金诺芬治疗,观察小鼠伤口愈合情况。
结果与结论:①细胞实验显示,干扰素γ(10 ng/mL)与脂多糖(100 ng/mL)联合处理能显著诱导RAW264.7细胞、THP-1细胞的M1型极化,表现为白细胞介素1β、白细胞介素6和肿瘤坏死因子α mRNA表达显著升高;金诺芬(1,2 μmol/L)处理后,细胞中炎症因子mRNA表达降低,细胞上清液中炎症因子分泌减少;②金诺芬显著抑制了NF-κB(p65)和p-MAPK信号通路的激活;③动物实验中,金诺芬促进了db/db小鼠伤口的愈合。结果表明,金诺芬具有良好的抗炎作用并可促进糖尿病小鼠伤口的愈合。

Abstract: BACKGROUND: During diabetic wound healing, the sustained activation of M1 macrophages exacerbates the inflammatory response and hinders wound repair. Auranofin, an anti-inflammatory drug, has not been clearly studied for its effects on M1 macrophages and its potential role in diabetic wound healing.
OBJECTIVE: To investigate the effects of different concentrations of auranofin on the biological function of M1 macrophages and evaluate its potential application in diabetic wound healing. 
METHODS: RAW264.7 and THP-1 cells were used as research models. M1 polarization was induced using different concentrations of interferon-γ and lipopolysaccharide. M1 macrophages were treated with 1 and 2 μmol/L auranofin. Cell counting kit-8 assay was used to evaluate the effect of auranofin on cell viability.  Quantitative real-time PCR was performed to detect mRNA expression of interleukin-1β, interleukin-6, and tumor necrosis factor-α. ELISA was employed to measure the levels of interleukin-1β, interleukin-6, and tumor necrosis factor-α in the supernatant. Western blot analysis was used to assess the expression of nuclear factor-κB (p65), phosphorylated mitogen-activated protein kinases (MAPK), and total MAPK proteins. Additionally, 6-8-week-old male C57BL/6J and db/db diabetic mice were used for wound healing experiments, with the mice divided into C57 control, db/db control and auranofin treatment groups, each containing six animals. Dorsal skin defect modeling and treatment with intraperitoneal injection of auranofin were performed to observe wound healing in mice.
RESULTS AND CONCLUSION: (1) Cell experiments showed that co-treatment with interferon-γ (10 ng/mL) and lipopolysaccharide (100 ng/mL) significantly induced M1 polarization in RAW264.7 and THP-1 cells, resulting in increased mRNA expression of interleukin-1β, interleukin-6, and tumor necrosis factor-α. Treatment with auranofin (1 and 2 μmol/L) reduced the mRNA expression of these inflammatory factors in the cells and inhibited the secretion of inflammatory factors in the cell supernatant. (2) Auranofin treatment significantly suppressed the activation of nuclear factor-κB (p65) and phosphorylated MAPK signaling pathways. (3) Animal experiments showed that auranofin promoted wound healing in db/db diabetic mice, suggesting that auranofin has strong anti-inflammatory effects and may facilitate the healing of wounds in diabetic mice.
