It infects the small intestine and intestinal villous cells, spreads rapidly, and causes infectious intestinal disease characterized by vomiting, diarrhea, and dehydration, leading to high mortality in newborn piglets and causing massive economic losses to the pig industry. The entry of PEDV into cells is mediated by the binding of its spike protein (S protein) to a host cell receptor. Here, we review the structure of PEDV, its strains, and the structure and function of the S protein shared by coronaviruses, and summarize the progress of research on possible host cell receptors since the discovery of PEDV.<\/jats:p>","DOI":"10.3390\/v14081744","type":"journal-article","created":{"date-parts":[[2022,8,10]],"date-time":"2022-08-10T09:47:06Z","timestamp":1660124826000},"page":"1744","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":127,"title":["PEDV: Insights and Advances into Types, Function, Structure, and Receptor Recognition"],"prefix":"10.3390","volume":"14","author":[{"given":"Feng","family":"Lin","sequence":"first","affiliation":[{"name":"College of Animal Sciences, Jilin University, Changchun 130062, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3982-4707","authenticated-orcid":false,"given":"Huanyu","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Animal Sciences, Jilin University, Changchun 130062, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linquan","family":"Li","sequence":"additional","affiliation":[{"name":"College of Animal Sciences, Jilin University, Changchun 130062, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8327-1281","authenticated-orcid":false,"given":"Yang","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Animal Sciences, Jilin University, Changchun 130062, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaodong","family":"Zou","sequence":"additional","affiliation":[{"name":"College of Animal Sciences, Jilin University, Changchun 130062, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiahuan","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Animal Sciences, Jilin University, Changchun 130062, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaochun","family":"Tang","sequence":"additional","affiliation":[{"name":"College of Animal Sciences, Jilin University, Changchun 130062, China"},{"name":"Chongqing Research Institute, Jilin University, Chongqing 401120, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"243","DOI":"10.1007\/BF01317606","article-title":"A new coronavirus-like particle associated with diarrhea in swine","volume":"58","author":"Pensaert","year":"1978","journal-title":"Arch.
