The pathogenic mechanism of chicken lung injury caused by the bacterium is unclear. Therefore, <jats:italic>P. multocida<\/jats:italic> Q (a reference standard strain isolated from chicken) and 1G1 (a clinic isolated strain from duck) were selected to infect chickens, establishing fowl cholera-induced laying hen models. Several important proteins involved in the process of lung injury were identified and quantified using immunohistochemistry and WB. The results showed that chicken lungs infected with bacteria for 24\u2009h showed congestion and edema. The inflammatory factors HMGB1 and IL-6, intercellular matrix MMP, the cell apoptosis-associated caspase-3 and necrotic apoptosis signal molecules RIPK1 and RIPK3 were widely expressed in the lungs of group Q and were significantly different compared with those of 1G1 group and uninfected group (P\u2009&lt;\u20090.05). The results indicated that RIPK1 and RIPK3 are involved in the injury process of chicken lungs after infection with <jats:italic>P. multocida<\/jats:italic>, and the mechanisms of lung injury induced by different strains are different.<\/jats:p>","DOI":"10.1038\/s41598-020-62042-7","type":"journal-article","created":{"date-parts":[[2020,4,14]],"date-time":"2020-04-14T10:03:12Z","timestamp":1586858592000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Receptor-interacting serine\/threonine kinase 1- and 3-dependent inflammation induced in lungs of chicken infected with Pasteurella multocida"],"prefix":"10.1038","volume":"10","author":[{"given":"Weitian","family":"Li","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiyu","family":"Tang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Na","family":"Dai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4114-6159","authenticated-orcid":false,"given":"Weikuan","family":"Feng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changqing","family":"Xie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guofu","family":"Cheng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoli","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wanpo","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xueying","family":"Hu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changqin","family":"Gu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,4,14]]},"reference":[{"key":"62042_CR1","first-page":"201","volume":"24","author":"SH Shi","year":"2009","unstructured":"Shi, S.
