Abstract

Enhanced production of reactive oxygen species (ROS) triggered by various stimuli, including viral infections, has attributed much attention in the past years. It has been shown that different viruses that cause acute or chronic diseases induce oxidative stress in infected cells and dysregulate antioxidant its antioxidant capacity. However, most studies focused on catalase and superoxide dismutases, whereas a family of peroxiredoxins (Prdx), the most effective peroxide scavengers, were given little or no attention. In the current review, we demonstrate that peroxiredoxins scavenge hydrogen and organic peroxides at their physiological concentrations at various cell compartments, unlike many other antioxidant enzymes, and discuss their recycling. We also provide data on the regulation of their expression by various transcription factors, as they can be compared with the imprint of viruses on transcriptional machinery. Next, we discuss the involvement of peroxiredoxins in transferring signals from ROS on specific proteins by promoting the oxidation of target cysteine groups, as well as briefly demonstrate evidence of nonenzymatic, chaperone, functions of Prdx. Finally, we give an account of the current state of research of peroxiredoxins for various viruses. These data clearly show that Prdx have not been given proper attention despite all the achievements in general redox biology.

摘要

在过去几年中,包括病毒感染在内的各种刺激所引发的活性氧(ROS)生成增加备受关注。研究表明,导致急性或慢性疾病的不同病毒会在受感染细胞中诱导氧化应激,并使其抗氧化能力失调。然而,大多数研究集中在过氧化氢酶和超氧化物歧化酶上,而作为最有效的过氧化物清除剂的过氧化物酶家族(Prdx)却很少或根本没有受到关注。在本综述中,我们证明,与许多其他抗氧化酶不同,过氧化物酶在各种细胞区室中以其生理浓度清除氢过氧化物和有机过氧化物,并讨论它们的循环利用。我们还提供了关于它们受各种转录因子调控表达的数据,因为它们可以与病毒在转录机制上的印记进行比较。接下来,我们讨论过氧化物酶通过促进靶标半胱氨酸基团的氧化,在将ROS信号传递给特定蛋白质过程中的作用,并简要展示过氧化物酶非酶促、伴侣功能的证据。最后,我们阐述了针对各种病毒的过氧化物酶研究现状。这些数据清楚地表明,尽管在一般氧化还原生物学方面取得了诸多成就,但过氧化物酶尚未得到应有的关注。
