However, selectins have been localized on the portal (presinusoidal) venules and these vessels have been shown to be important in metastasis of tumors. The purpose of this study was to characterize the leukocyte-endothelial interactions within the 3 compartments of the hepatic microvasculature under baseline conditions and in response to tumor necrosis factor \u03b1 (TNF-\u03b1). Mice deficient in P-selectin or both E- and P-selectin were compared with wild-type (C57Bl\/6, wild type) mice. Animals were injected with murine TNF-\u03b1 (15 \u03bcg\/kg intraperitoneally [IP]) and the liver was examined by fluorescence intravital microscopy 4 hours later. Under baseline conditions, leukocyte flux in the portal venules was 1.42 \u00b1 0.42 cells\/min. Leukocyte flux in the portal venules of wild-type mice increased 8-fold in response to 4 hours of TNF-\u03b1 stimulation. This was reduced by 50% in the P-selectin-deficient mice but was not reduced further by either the addition of an E-selectin antibody (9A9, 100 \u03bcg intravenously [IV]) to these mice or in mice deficient in both E- and P-selectin. In P-selectin-deficient mice, the addition of an antibody against \u03b1<jats:sub>4<\/jats:sub>-integrin (R1-2, 75 \u03bcg IP) reduced rolling to baseline. But in the E- and P-double-selectin-deficient mice the addition of an antibody against L-selectin (Mel 14, 3 \u03bcg\/kg IV) had no effect on TNF-\u03b1-induced recruitment. Similar responses were seen in the central venules, however, in the sinusoids the increased number of stationary leukocytes seen in response to 4 hours of TNF-\u03b1 stimulation in the wild-type mice was not reduced in P-selectin-deficient mice with or without the \u03b1<jats:sub>4<\/jats:sub>-integrin antibody. These data suggest that leukocytes can use \u03b1<jats:sub>4<\/jats:sub>-integrin independent of the selectins in the venules. Within the sinusoids, however, inhibition of E-selectin, P-selectin, and \u03b1<jats:sub>4<\/jats:sub>-integrin was insufficient to reduce leukocyte recruitment.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1053\/he.2000.6961","type":"journal-article","created":{"date-parts":[[2004,3,19]],"date-time":"2004-03-19T18:32:14Z","timestamp":1079721134000},"page":"1123-1127","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":87,"title":["Molecular mechanisms of tumor necrosis factor \u03b1-stimulated leukocyte recruitment into the murine hepatic circulation"],"prefix":"10.1097","volume":"31","author":[{"given":"Alison","family":"Fox-Robichaud","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Kubes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"10.1053\/he.2000.6961-BIB1","doi-asserted-by":"crossref","first-page":"415","DOI":"10.1111\/j.1748-1716.1992.tb09442.x","volume":"146","author":"Lindbom","year":"1992","journal-title":"Acta Physiol Scand"},{"key":"10.1053\/he.2000.6961-BIB2","doi-asserted-by":"crossref","first-page":"669","DOI":"10.1084\/jem.181.2.669","volume":"181","author":"Ley","year":"1995","journal-title":"J Exp Med"},{"key":"10.1053\/he.2000.6961-BIB3","first-page":"h1637","volume":"267","author":"Nolte","year":"1994","journal-title":"Am J Physiol"},{"key":"10.1053\/he.2000.6961-BIB4","doi-asserted-by":"crossref","first-page":"2782","DOI":"10.1172\/JCI119468","volume":"99","author":"Wong","year":"1997","journal-title":"J Clin Invest"},{"key":"10.1053\/he.2000.6961-BIB5","first-page":"g828","volume":"276","author":"Carvalho-Tavares","year":"1999","journal-title":"Am J Physiol"},{"key":"10.1053\/he.2000.6961-BIB6","doi-asserted-by":"crossref","first-page":"288","DOI":"10.1002\/jlb.63.3.288","volume":"63","author":"Essani","year":"1998","journal-title":"J Leukoc Biol"},{"key":"10.1053\/he.2000.6961-BIB7","doi-asserted-by":"crossref","first-page":"2443","DOI":"10.1172\/JCI117612","volume":"94","author":"Jones","year":"1994","journal-title":"J Clin Invest"},{"key":"10.1053\/he.2000.6961-BIB8","doi-asserted-by":"crossref","first-page":"74","DOI":"10.1006\/bbrc.1995.1780","volume":"211","author":"Essani","year":"1995","journal-title":"Biochem Biophys Res Commun"},{"key":"10.1053\/he.2000.6961-BIB9","doi-asserted-by":"crossref","first-page":"520","DOI":"10.1182\/blood.V92.2.520","volume":"92","author":"Shi","year":"1998","journal-title":"Blood"},{"key":"10.1053\/he.2000.6961-BIB10","first-page":"4105","volume":"57","author":"Scherbarth","year":"1997","journal-title":"Cancer Res"},{"key":"10.1053\/he.2000.6961-BIB11","doi-asserted-by":"crossref","first-page":"377","DOI":"10.1007\/BF00132981","volume":"11","author":"Morris","year":"1993","journal-title":"Clin Exp Metastasis"},{"key":"10.1053\/he.2000.6961-BIB12","doi-asserted-by":"crossref","first-page":"491","DOI":"10.1016\/S0889-8553(05)70067-4","volume":"28","author":"Raj","year":"1999","journal-title":"Gastroenterol Clin North Am"},{"key":"10.1053\/he.2000.6961-BIB13","doi-asserted-by":"crossref","first-page":"2329","DOI":"10.1084\/jem.183.5.2329","volume":"183","author":"Bullard","year":"1996","journal-title":"J Exp Med"},{"key":"10.1053\/he.2000.6961-BIB14","doi-asserted-by":"crossref","first-page":"2099","DOI":"10.1172\/JCI119744","volume":"100","author":"Munoz","year":"1997","journal-title":"J Clin Invest"},{"key":"10.1053\/he.2000.6961-BIB15","first-page":"247","volume-title":"Physical Techniques in Biology and Medicine Microvascular Technology","author":"McCuskey","year":"1986","unstructured":"Microscopic methods for studying the microvascular circulation of internal organs.
