We utilize primary human nasal epithelial cells grown at air\u2013liquid interface, which recapitulate the heterogeneous cellular population as well as mucociliary clearance functions of the in\u00a0vivo nasal epithelium, to compare lethal [Severe acute respiratory syndrome (SARS)-CoV-2 and Middle East respiratory syndrome-CoV (MERS-CoV)] and seasonal (HCoV-NL63 and HCoV-229E) HCoVs. All four HCoVs replicate productively in nasal cultures, though replication is differentially modulated by temperature. Infections conducted at 33 \u00b0C vs. 37 \u00b0C (reflective of temperatures in the upper and lower airway, respectively) revealed that replication of both seasonal HCoVs (HCoV-NL63 and -229E) is significantly attenuated at 37 \u00b0C. In contrast, SARS-CoV-2 and MERS-CoV replicate at both temperatures, though SARS-CoV-2 replication is enhanced at 33 \u00b0C late in infection. These HCoVs also diverge significantly in terms of cytotoxicity induced following infection, as the seasonal HCoVs as well as SARS-CoV-2 cause cellular cytotoxicity as well as epithelial barrier disruption, while MERS-CoV does not. Treatment of nasal cultures with type 2 cytokine IL-13 to mimic asthmatic airways differentially impacts HCoV receptor availability as well as replication. MERS-CoV receptor DPP4 expression increases with IL-13 treatment, whereas ACE2, the receptor used by SARS-CoV-2 and HCoV-NL63, is down-regulated. IL-13 treatment enhances MERS-CoV and HCoV-229E replication but reduces that of SARS-CoV-2 and HCoV-NL63, reflecting the impact of IL-13 on HCoV receptor availability. This study highlights diversity among HCoVs during infection of the nasal epithelium, which is likely to influence downstream infection outcomes such as disease severity and transmissibility.<\/jats:p>","DOI":"10.1073\/pnas.2218083120","type":"journal-article","created":{"date-parts":[[2023,4,6]],"date-time":"2023-04-06T13:45:10Z","timestamp":1680788710000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":66,"title":["Infection of primary nasal epithelial cells differentiates among lethal and seasonal human coronaviruses"],"prefix":"10.1073","volume":"120","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1609-8105","authenticated-orcid":false,"given":"Clayton\u00a0J.","family":"Otter","sequence":"first","affiliation":[{"name":"Department of Microbiology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA 19104"},{"name":"Penn Center for Research on Coronaviruses and Other Emerging Pathogens, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA 19104"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alejandra","family":"Fausto","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA 19104"},{"name":"Penn Center for Research on Coronaviruses and Other Emerging Pathogens, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA 19104"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li\u00a0Hui","family":"Tan","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology-Head and Neck Surgery, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA 19104"},{"name":"Department of Surgery, Corporal Michael J.
