In the current study, the role of CD47 in PMN transmigration and infiltration into tissues was further evaluated by investigating the function of CD47\u2212\/\u2212 PMN and inflammatory conditions induced in CD47\u2212\/\u2212 mice. Using in vitro time-course assays, we found that CD47\u2212\/\u2212 PMN exhibited no impediment, but slightly enhanced response to and transmigration toward, the chemoattractant fMLF. In vivo analysis in CD47\u2212\/\u2212 mice by inducing acute peritonitis and aggressive colitis observed consistent results, indicating that both PMN and monocytes effectively infiltrated inflammatory sites despite the absence of CD47 on these leukocytes or the surrounding tissue cells. Although PMN transmigration was not delayed in CD47\u2212\/\u2212 mice, fewer PMN were found in the intestine at the postacute\/chronic stage of chronic colitis induced with sustained low-dose dextran sulfate sodium. Further analysis suggested that the paucity of PMN accumulation was attributable to attenuated granulopoiesis secondary to assessed lower levels of IL-17. Administration of exogenous IL-17A markedly increased PMN availability and rapidly rendered severe colitis in CD47\u2212\/\u2212 mice under dextran sulfate sodium treatment.<\/jats:p>","DOI":"10.4049\/jimmunol.1201963","type":"journal-article","created":{"date-parts":[[2012,12,2]],"date-time":"2012-12-02T01:35:45Z","timestamp":1354412145000},"page":"411-417","source":"Crossref","is-referenced-by-count":19,"title":["CD47 Deficiency Does Not Impede Polymorphonuclear Neutrophil Transmigration but Attenuates Granulopoiesis at the Postacute Stage of Colitis"],"prefix":"10.1093","volume":"190","author":[{"given":"Zhen","family":"Bian","sequence":"first","affiliation":[{"name":"Program of Cellular Biology and Immunology, Department of Biology, Center for Inflammation, Immunity and Infection, Georgia State University , Atlanta, GA 30303"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"YaLan","family":"Guo","sequence":"additional","affiliation":[{"name":"Program of Cellular Biology and Immunology, Department of Biology, Center for Inflammation, Immunity and Infection, Georgia State University , Atlanta, GA 30303"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Youqun","family":"Luo","sequence":"additional","affiliation":[{"name":"Program of Cellular Biology and Immunology, Department of Biology, Center for Inflammation, Immunity and Infection, Georgia State University , Atlanta, GA 30303"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandra","family":"Tremblay","sequence":"additional","affiliation":[{"name":"Program of Cellular Biology and Immunology, Department of Biology, Center for Inflammation, Immunity and Infection, Georgia State University , Atlanta, GA 30303"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiugen","family":"Zhang","sequence":"additional","affiliation":[{"name":"Program of Cellular Biology and Immunology, Department of Biology, Center for Inflammation, Immunity and Infection, Georgia State University , Atlanta, GA 30303"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sanam","family":"Dharma","sequence":"additional","affiliation":[{"name":"Program of Cellular Biology and Immunology, Department of Biology, Center for Inflammation, Immunity and Infection, Georgia State University , Atlanta, GA 30303"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aarti","family":"Mishra","sequence":"additional","affiliation":[{"name":"Program of Cellular Biology and Immunology, Department of Biology, Center for Inflammation, Immunity and Infection, Georgia State University , Atlanta, GA 30303"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuan","family":"Liu","sequence":"additional","affiliation":[{"name":"Program of Cellular Biology and Immunology, Department of Biology, Center for Inflammation, Immunity and Infection, Georgia State University , Atlanta, GA 30303"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2013,1,1]]},"reference":[{"key":"2025032406212150400_r1","doi-asserted-by":"crossref","first-page":"3978","DOI":"10.1073\/pnas.92.9.3978","article-title":"Transendothelial migration of neutrophils involves integrin-associated protein (CD47)","volume":"92","author":"Cooper","year":"1995","journal-title":"Proc.
