Wound healing is initiated and progressed by complex integrated process of cellular, physiologic, and biochemical events, such as inflammation, cell migration and proliferation. Interleukin 6 (IL-6) is a multifunctional cytokine, and it could regulate the inflammatory response of wound healing process in a timely manner. Hyaluronic acid (HA) is an essential component of the extracellular matrix, and contributes significantly to cell proliferation and migration. The purpose of this study was to investigate the effects of IL-6 or/and HA on the cell migration process in human keratinocytes. Combining IL-6 and HA significantly increased the cell migration in scratch based wound healing assay. The phosphorylation of extracellular-signal-regulated kinase (ERK) was significantly increased after 1 hr of IL-6 and HA treatment, but the phosphorylation of p38 mitogen-activated protein kinase (MAPK) was not. We also found that significant increase of the NF-κB translocation from cytoplasm into nucleus after 1 hr of IL-6 or/and HA treatments. This study firstly showed that synergistic effects of combining IL-6 and HA on the cell migration of wound healing by activation of ERK and NF-κB signaling. Further studies might be required to confirm the synergistic effects of HA and IL-6 in the animal model for the development of a novel therapeutic mixture for stimulation of wound healing process.
伤口愈合是由细胞、生理和生化事件等复杂的综合过程启动并推进的,如炎症、细胞迁移和增殖。白细胞介素6(IL-6)是一种多功能细胞因子,它可以及时调节伤口愈合过程中的炎症反应。透明质酸(HA)是细胞外基质的重要组成部分,对细胞增殖和迁移有显著贡献。本研究的目的是探讨IL-6或/和HA对人角质形成细胞中细胞迁移过程的影响。在划痕法伤口愈合试验中,联合使用IL-6和HA可显著增加细胞迁移。IL-6和HA处理1小时后,细胞外信号调节激酶(ERK)的磷酸化显著增加,但p38丝裂原活化蛋白激酶(MAPK)的磷酸化没有增加。我们还发现,IL-6或/和HA处理1小时后,核因子κB(NF-κB)从细胞质向细胞核的转位显著增加。本研究首次表明,IL-6和HA联合通过激活ERK和NF-κB信号通路对伤口愈合中的细胞迁移具有协同作用。可能需要进一步的研究来证实HA和IL-6在动物模型中的协同作用,以开发一种新型治疗混合物来促进伤口愈合过程。
