However, cilia beating features in a CF altered environment, consisting of dehydrated airway surface liquid layer and abnormal mucus, have not been fully characterized. Furthermore, acute inflammation is normally followed by an active resolution phase requiring specialized proresolving lipid mediators (SPMs) and allowing return to homeostasis. However, altered SPMs biosynthesis has been reported in CF. Here, we explored cilia beating dynamics in CF airways primary cultures and its response to the SPMs, resolvin E1 (RvE1) and lipoxin B4 (LXB4). Human nasal epithelial cells (hNECs) from CF and non-CF donors were grown at air\u2013liquid interface. The ciliary beat frequency, synchronization, orientation, and density were analyzed from high-speed video microscopy using a multiscale Differential Dynamic Microscopy algorithm and an in-house developed method. Mucins and ASL layer height were studied by qRT-PCR and confocal microscopy. Principal component analysis showed that CF and non-CF hNEC had distinct cilia beating phenotypes, which was mostly explained by differences in cilia beat organization rather than frequency. Exposure to RvE1 (10 nM) and to LXB4 (10 nM) restored a non-CF-like cilia beating phenotype. Furthermore, RvE1 increased the airway surface liquid (ASL) layer height and reduced the mucin MUC5AC thickness. The calcium-activated chloride channel, TMEM16A, was involved in the RvE1 effect on cilia beating, hydration, and mucus. Altogether, our results provide evidence for defective cilia beating in CF airway epithelium and a role of RvE1 and LXB4 to restore the main epithelial functions involved in the mucociliary clearance.<\/jats:p>","DOI":"10.1073\/pnas.2313089121","type":"journal-article","created":{"date-parts":[[2024,1,22]],"date-time":"2024-01-22T15:07:01Z","timestamp":1705936021000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":9,"title":["Specialized proresolving mediator resolvin E1 corrects the altered cystic fibrosis nasal epithelium cilia beating dynamics"],"prefix":"10.1073","volume":"121","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-5423-1236","authenticated-orcid":false,"given":"Ma\u00eblle","family":"Briottet","sequence":"first","affiliation":[{"name":"INSERM U955, Cr\u00e9teil 94000, France"},{"name":"Universit\u00e9 Paris Est, Facult\u00e9 de m\u00e9decine, Cr\u00e9teil 94000, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khadeeja","family":"Sy","sequence":"additional","affiliation":[{"name":"INSERM U955, Cr\u00e9teil 94000, France"},{"name":"Universit\u00e9 Paris Est, Facult\u00e9 de m\u00e9decine, Cr\u00e9teil 94000, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-1384-7328","authenticated-orcid":false,"given":"Charlie","family":"London","sequence":"additional","affiliation":[{"name":"INSERM U955, Cr\u00e9teil 94000, France"},{"name":"Universit\u00e9 Paris Est, Facult\u00e9 de m\u00e9decine, Cr\u00e9teil 94000, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdel","family":"Aissat","sequence":"additional","affiliation":[{"name":"INSERM U955, Cr\u00e9teil 94000, France"},{"name":"Universit\u00e9 Paris Est, Facult\u00e9 de m\u00e9decine, Cr\u00e9teil 94000, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mickael","family":"Shum","sequence":"additional","affiliation":[{"name":"INSERM U955, Cr\u00e9teil 94000, France"},{"name":"Universit\u00e9 Paris Est, Facult\u00e9 de m\u00e9decine, Cr\u00e9teil 94000, France"},{"name":"Centre Hospitalier Intercommunal de Cr\u00e9teil, Cr\u00e9teil 94000, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0208-7544","authenticated-orcid":false,"given":"Virginie","family":"Escabasse","sequence":"additional","affiliation":[{"name":"INSERM U955, Cr\u00e9teil 94000, France"},{"name":"Universit\u00e9 Paris Est, Facult\u00e9 de m\u00e9decine, Cr\u00e9teil 94000, France"},{"name":"Centre Hospitalier Intercommunal de Cr\u00e9teil, Cr\u00e9teil 94000, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9587-9932","authenticated-orcid":false,"given":"Bruno","family":"Louis","sequence":"additional","affiliation":[{"name":"INSERM U955, Cr\u00e9teil 94000, France"},{"name":"Universit\u00e9 Paris Est, Facult\u00e9 de m\u00e9decine, Cr\u00e9teil 94000, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7437-9365","authenticated-orcid":false,"given":"Val\u00e9rie","family":"Urbach","sequence":"additional","affiliation":[{"name":"INSERM U955, Cr\u00e9teil 94000, France"},{"name":"Universit\u00e9 Paris Est, Facult\u00e9 de m\u00e9decine, Cr\u00e9teil 94000, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2024,1,22]]},"reference":[{"key":"e_1_3_4_1_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.2475911"},{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00431-021-04168-y"},{"key":"e_1_3_4_3_2","first-page":"1075","article-title":"Early pulmonary inflammation in infants with cystic fibrosis","volume":"151","author":"Khan T.
