Interaction between TANs and TAMs enhanced the proliferation and invasion abilities of ICC cells in vitro and tumor progression in a mouse xenograft model of ICC. TANs and TAMs produced higher levels of oncostatin M and interleukin-11, respectively, in co-culture than in monoculture. Both of those cytokines activated STAT3 signaling in ICC cells. Knockdown of STAT3 abolished the protumor effect of TANs and TAMs on ICC. In tumor samples from patients with ICC, increased TAN and TAM levels were correlated with elevated p-STAT3 expression. All three of those factors were independent predictors of patient outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>TANs and TAMs interact to promote ICC progression by activating STAT3.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1136\/jitc-2020-001946","type":"journal-article","created":{"date-parts":[[2021,3,10]],"date-time":"2021-03-10T11:51:21Z","timestamp":1615377081000},"page":"e001946","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":134,"title":["Tumor-associated neutrophils and macrophages interaction contributes to intrahepatic cholangiocarcinoma progression by activating STAT3"],"prefix":"10.1136","volume":"9","author":[{"given":"Zhengjun","family":"Zhou","sequence":"first","affiliation":[{"name":"Department of Liver Surgery and Transplantation, Liver Cancer Institute, Zhongshan Hospital, Fudan University;
