Reactive oxygen species (ROS) play a significant role in the survival and decline of various biological systems. In liver-related metabolic disorders such as steatohepatitis, ROS can act as both a cause and a consequence. Alcoholic steatohepatitis (ASH) and non-alcoholic steatohepatitis (NASH) are two distinct types of steatohepatitis. Recently, there has been growing interest in using medications that target ROS formation and reduce ROS levels as a therapeutic approach for oxidative stress-related liver disorders. Mammalian systems have developed various antioxidant defenses to protect against excessive ROS generation. These defenses modulate ROS through a series of reactions, limiting their potential impact. However, as the condition worsens, exogenous antioxidants become necessary to control ROS levels. Nanotechnology has emerged as a promising avenue, utilizing nanocomplex systems as efficient nano-antioxidants. These systems demonstrate enhanced delivery of antioxidants to the target site, minimizing leakage and improving targeting accuracy. Therefore, it is essential to explore the evolving field of nanotechnology as an effective means to lower ROS levels and establish efficient therapeutic interventions for oxidative stress-related liver disorders.
活性氧(ROS)在各种生物系统的存活和衰退中起着重要作用。在诸如脂肪性肝炎等肝脏相关代谢紊乱中,ROS既可以是病因,也可以是结果。酒精性脂肪性肝炎(ASH)和非酒精性脂肪性肝炎(NASH)是两种不同类型的脂肪性肝炎。最近,人们越来越关注使用靶向ROS形成并降低ROS水平的药物,作为治疗与氧化应激相关的肝脏疾病的一种方法。哺乳动物系统已经发展出各种抗氧化防御机制来抵御过量ROS的产生。这些防御机制通过一系列反应调节ROS,限制其潜在影响。然而,随着病情恶化,外源性抗氧化剂对于控制ROS水平变得必要。纳米技术已成为一条有前景的途径,利用纳米复合系统作为高效的纳米抗氧化剂。这些系统显示出抗氧化剂向靶位点的增强递送,最大限度地减少泄漏并提高靶向准确性。因此,探索纳米技术这一不断发展的领域,作为降低ROS水平的有效手段,并为与氧化应激相关的肝脏疾病建立有效的治疗干预措施至关重要。
