Many progressive neurodegenerative diseases, such as Huntington\u2019s disease (HD) and Alzheimer\u2019s disease (AD), are characterized by an age-dependent failure of the proteostasis network to sustain the health of the proteome, resulting in protein misfolding, aggregation, and, often, neurotoxicity. Although important advances have been made in recent years to identify genetic risk factors for neurodegenerative diseases, we still know relatively little about environmental risk factors such as air pollution. Exposure to nano-sized particulate air pollution, referred to herein as nanoparticulate matter (nPM), has been shown to trigger the accumulation of misfolded and oligomerized amyloid beta (A\u03b2) in mice. Likewise, air pollution is known to exacerbate symptoms of AD in people. We asked whether nPM contributes to the misfolded protein load, thereby overwhelming the proteostasis network and triggering proteostasis decline. To address this, we utilized <jats:italic>C<\/jats:italic>. <jats:italic>elegans<\/jats:italic> that express reporter proteins that are sensitive to changes in the protein folding environment and respond by misfolding and displaying readily scorable phenotypes, such as localized YFP fluorescence or paralysis. We found that nPM exacerbated protein aggregation in body wall muscle cells, increasing the number of large visible protein aggregates, the amount of high molecular weight protein species, and proteotoxicity. Taken together, the data point to nPM negatively impacting proteostasis. Therefore, it seems plausible that nPM exposure may exacerbate symptoms of AD and age-related dementia in a manner that is at least partially dependent on proteostasis decline.<\/jats:p>","DOI":"10.1371\/journal.pone.0275137","type":"journal-article","created":{"date-parts":[[2023,2,23]],"date-time":"2023-02-23T18:33:25Z","timestamp":1677177205000},"page":"e0275137","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":9,"title":["Nanoparticulate air pollution disrupts proteostasis in Caenorhabditis elegans"],"prefix":"10.1371","volume":"18","author":[{"given":"Bailey A.","family":"Garcia Manriquez","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julia A.","family":"Papapanagiotou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claire A.","family":"Strysick","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emily H.","family":"Green","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3639-8028","authenticated-orcid":true,"given":"Elise A.","family":"Kikis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2023,2,23]]},"reference":[{"issue":"7","key":"pone.0275137.ref001","doi-asserted-by":"crossref","first-page":"421","DOI":"10.1038\/s41580-019-0101-y","article-title":"The proteostasis network and its decline in ageing","volume":"20","author":"M.S.
