To determine the contribution of FasL to mortality, we conducted survival studies by blocking Fas\/FasL with Fas receptor fusion protein (FasFP) in vivo. C3H\/HeN mice received FasFP or the saline vehicle (veh) immediately (0 h) or delayed (12 h), after sepsis induced by cecal ligation and puncture (CLP). Subsequently, we examined the effect of FasFP treatment (12 h post-CLP) on macrophage apoptosis and functional capacities. Peritoneal and splenic macrophages and Kupffer cells from sham-veh-, CLP-veh-, sham-FasFP-, or CLP-FasFP-treated mice were harvested 24 h after CLP and stimulated with lipopolysaccharide (LPS) for 24 h. The results indicate that only delayed (12 h) but not 0 h administration of FasFP demonstrated a significant increase in survival. The ability of all macrophage populations to release interleukin (IL)-6 was significantly depressed, and IL-10 release was augmented after CLP. FasFP treatment attenuated the increased IL-10 release in Kupffer cells. However, althogh enhanced susceptibility to LPS-induced apoptosis could be suppressed in CLP mouse Kupffer cells by FasFP, FasFP did not change the peritoneal or splenic macrophage response. Furthermore, FasFP attenuated the elevated plasma levels of liver enzymes after sepsis. These data indicate that in vivo inhibition of Fas\/FasL signaling has tissue-specific effects on the induction of macrophage apoptosis, functional changes, and liver damage, which may contribute to the host\u2019s ability to ward off a septic challenge.<\/jats:p>","DOI":"10.1189\/jlb.0102006","type":"journal-article","created":{"date-parts":[[2003,8,29]],"date-time":"2003-08-29T20:50:15Z","timestamp":1062190215000},"page":"344-351","source":"Crossref","is-referenced-by-count":95,"title":["Inhibition of Fas\/Fas ligand signaling improves septic survival: differential effects on macrophage apoptotic and functional capacity"],"prefix":"10.1093","volume":"74","author":[{"given":"Chun-Shiang","family":"Chung","sequence":"first","affiliation":[{"name":"Surgical Research, Department of Surgery, Brown University School of Medicine and Rhode Island Hospital , Providence"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Grace Y","family":"Song","sequence":"additional","affiliation":[{"name":"Surgical Research, Department of Surgery, Brown University School of Medicine and Rhode Island Hospital , Providence"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joanne","family":"Lomas","sequence":"additional","affiliation":[{"name":"Surgical Research, Department of Surgery, Brown University School of Medicine and Rhode Island Hospital , Providence"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H Hank","family":"Simms","sequence":"additional","affiliation":[{"name":"Department of Surgery, North Shore University Hospital , Manhasset, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Irshad H","family":"Chaudry","sequence":"additional","affiliation":[{"name":"Department of Surgery, University of Alabama at Birmingham School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alfred","family":"Ayala","sequence":"additional","affiliation":[{"name":"Surgical Research, Department of Surgery, Brown University School of Medicine and Rhode Island Hospital , Providence"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2003,6,3]]},"reference":[{"key":"2023033100464278000_jlb0344-cit-B1","first-page":"161","article-title":"Sepsis and multiple organ failure: the result of whole body inflammation","author":"Goris","year":"1993"},{"key":"2023033100464278000_jlb0344-cit-B2","doi-asserted-by":"crossref","first-page":"1125","DOI":"10.1097\/00003246-199607000-00010","article-title":"Sir Issac Newton, sepsis, SIRS and CARS","volume":"24","author":"Bone","year":"1996","journal-title":"Crit.
