Age-related macular degeneration (AMD) is an eye disease that is characterized by damage to the central part of the retina, the macula, and that affects millions of people worldwide. At an advanced stage, a blind spot grows in the center of vision, severely handicapping patients with this degenerative condition. Despite therapeutic advances thanks to the use of anti-VEGF, many resistance mechanisms have been found to accentuate the visual deficit. In the present study, we explored whether supplementation with Resvega, a nutraceutical formulation composed of omega-3 fatty acids and resveratrol, a well-known polyphenol in grapes, was able to counteract laser-induced choroidal neovascularization (CNV) in mice. We highlight that Resvega significantly reduced CNV in mice compared with supplementations containing omega-3 or resveratrol alone. Moreover, a proteomic approach confirmed that Resvega could counteract the progression of AMD through a pleiotropic effect targeting key regulators of neoangiogenesis in retina cells in vivo. These events were associated with an accumulation of resveratrol metabolites within the retina. Therefore, a supplementation of omega-3/resveratrol could improve the management or slow the progression of AMD in patients with this condition.
年龄相关性黄斑变性(AMD)是一种眼部疾病,其特征是视网膜中央部分——黄斑受损,全球有数百万患者受到影响。在晚期,视力中心会出现盲点,严重影响患有这种退行性疾病的患者。尽管由于使用抗 VEGF 而取得了治疗进展,但发现了许多抵抗机制,使视力缺陷更加严重。在本研究中,我们探讨了补充 Resvega(一种由 omega-3 脂肪酸和白藜芦醇组成的营养配方,白藜芦醇是葡萄中的一种著名多酚)是否能够抵抗小鼠的激光诱导脉络膜新生血管形成(CNV)。我们强调,与单独补充 omega-3 或白藜芦醇相比,Resvega 可显著减少小鼠的 CNV。此外,蛋白质组学方法证实,Resvega 可以通过针对体内视网膜细胞中新血管生成关键调节剂的多效作用来抵抗 AMD 的进展。这些事件与视网膜内白藜芦醇代谢物的积累有关。因此,omega-3/白藜芦醇的补充可能会改善这种情况下患者的疾病管理或减缓疾病的进展。
