The brain is particularly vulnerable to CO toxicity, and thus the majority of survivors develop delayed movement and cognitive complications. CO binds to haemoglobin in erythrocytes, preventing oxygen delivery to tissues, and additionally inhibits mitochondrial respiration. This renders the effect of CO to be closely related to hypoxia reperfusion injury. Oxygen deprivation, as well as CO poisoning and re-oxygenation, are shown to be able to activate the production of reactive oxygen species and to induce oxidative stress. Here, we review the role of reactive oxygen species production and oxidative stress in the mechanism of neuronal cell death induced by carbon monoxide and re-oxygenation. We discuss possible protective mechanisms used by brain cells with a specific focus on the inhibition of CO-induced ROS production and oxidative stress.<\/jats:p>","DOI":"10.3390\/antiox13091121","type":"journal-article","created":{"date-parts":[[2024,9,16]],"date-time":"2024-09-16T10:56:57Z","timestamp":1726484217000},"page":"1121","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Carbon Monoxide: A Pleiotropic Redox Regulator of Life and Death"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7646-7235","authenticated-orcid":false,"given":"Andrey Y.","family":"Abramov","sequence":"first","affiliation":[{"name":"UCL Queen Square Institute of Neurology, Department of Clinical and Movement Neurosciences, Queen Square, London WC1N3BG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3783-1222","authenticated-orcid":false,"given":"Isabella","family":"Myers","sequence":"additional","affiliation":[{"name":"UCL Queen Square Institute of Neurology, Department of Clinical and Movement Neurosciences, Queen Square, London WC1N3BG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4596-9117","authenticated-orcid":false,"given":"Plamena R.","family":"Angelova","sequence":"additional","affiliation":[{"name":"UCL Queen Square Institute of Neurology, Department of Clinical and Movement Neurosciences, Queen Square, London WC1N3BG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,16]]},"reference":[{"key":"ref_1","unstructured":"GBD 2021 Carbon Monoxide Poisoning Collaborators (2023).
