Abstract

PM_2.5 is fine particulate matter with a diameter of less than 2.5 μm. Recent evidence has shown that exposure to PM_2.5 markedly elevates the risk of neurodegenerative diseases, neurodevelopmental disorders, and cardiovascular diseases, which may culminate in cognitive impairment. Nevertheless, the precise mechanisms through which PM_2.5 affects cognitive function are unclear. Recent studies have demonstrated that PM_2.5-induced epigenetic alterations are associated with the development of cognitive impairment. Epigenetic alterations include modifications to DNA methylation, histone modifications, and non-coding RNAs. The underlying mechanisms of epigenetic alterations are related to inflammation, synaptic dysfunction, cardiovascular factors, and alterations in neuronal structure and function. This review reports the latest findings on the relationship between PM_2.5-induced epigenetic alterations and the development of cognitive disorders, offering novel insights into the cognitive effects of air pollution.

表观遗传机制在pm2.5诱导的认知障碍发展中的作用。

PM2.5是指直径小于2.5 μm的细颗粒物。最近的证据表明，暴露于PM2.5会显著增加患神经退行性疾病、神经发育障碍和心血管疾病的风险，最终可能导致认知障碍。然而，PM2.5影响认知功能的确切机制尚不清楚。最近的研究表明，pm2.5诱导的表观遗传改变与认知障碍的发展有关。表观遗传改变包括DNA甲基化、组蛋白修饰和非编码rna的修饰。表观遗传改变的潜在机制与炎症、突触功能障碍、心血管因素以及神经元结构和功能的改变有关。本文综述了pm2.5诱导的表观遗传改变与认知障碍发展之间关系的最新发现，为空气污染对认知的影响提供了新的见解。

期刊介绍： Toxics (ISSN 2305-6304) is an international, peer-reviewed, open access journal which provides an advanced forum for studies related to all aspects of toxic chemicals and materials. It publishes reviews, regular research papers, and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in detail. There is, therefore, no restriction on the maximum length of the papers, although authors should write their papers in a clear and concise way. The full experimental details must be provided so that the results can be reproduced. Electronic files or software regarding the full details of calculations and experimental procedure can be deposited as supplementary material, if it is not possible to publish them along with the text.
