Skin fibrosis is a debilitating condition that significantly impacts patient quality of life. Ultraviolet phototherapy is currently used to treat several diseases featuring skin fibrosis. High-fluence light-emitting diode-generated red light (HF-LED-RL) does not cause DNA damage associated with skin cancer, and it is generally regarded as safe, portable, and cost-effective. Early clinical observations suggest that LED-generated light may possess antifibrotic effects, although these findings are largely unexplored. Previously published research demonstrated that HF-LED-RL decreases fibroblast proliferation and collagen in vitro.
The goal of this study was to compare the combination effects of HF-LED-RL alone with HF-LED-RL in combination with resveratrol.
It is hypothesized that resveratrol, an active ingredient in red wine, a potent antioxidant scavenger of reactive oxygen species, and an inhibitor of collagen production, may synergistically decrease fibroblast proliferation and collagen production when combined with HF-LED-RL.
In this study, evidence is provided that resveratrol combined with HF-LED-RL acts synergistically to decrease fibroblast proliferation and procollagen 1A1 production, and this represents a new potential therapeutic modality that is termed the "photobotanical" effect due to the combined light and botanical properties observed.
The study, discovery, and use of photobotanical combinations may usher in new therapeutics or phototherapy adjuvants for the treatment of dermatologic diseases.
皮肤纤维化是一种使人衰弱的病症,会显著影响患者的生活质量。紫外线光疗目前用于治疗多种以皮肤纤维化为特征的疾病。高能量发光二极管产生的红光(HF-LED-RL)不会导致与皮肤癌相关的DNA损伤,并且通常被认为是安全、便携且具有成本效益的。早期临床观察表明,LED产生的光可能具有抗纤维化作用,尽管这些发现大多尚未得到充分探索。先前发表的研究表明,HF-LED-RL在体外可减少成纤维细胞增殖和胶原蛋白。
本研究的目的是比较单独使用HF-LED-RL与HF-LED-RL联合白藜芦醇的联合效果。
据推测,白藜芦醇是红酒中的一种活性成分,是一种强效的活性氧清除剂和胶原蛋白生成抑制剂,与HF-LED-RL联合使用时可能协同降低成纤维细胞增殖和胶原蛋白生成。
在本研究中,有证据表明白藜芦醇与HF-LED-RL联合使用具有协同作用,可降低成纤维细胞增殖和前胶原1A1生成,这代表了一种新的潜在治疗方式,由于观察到光和植物成分的联合作用,被称为“光植物”效应。
光植物组合的研究、发现和使用可能会为皮肤病的治疗带来新的治疗方法或光疗佐剂。
