In sickle mouse models, inflammatory stimuli (e.g., hypoxia-reoxygenation and cytokines) result in increased leukocyte recruitment and can initiate vasoocclusion, suggesting that anti-inflammatory therapy could be beneficial in management of this disease. We have tested the hypothesis that inhibition of endothelial activation in a transgenic mouse model by anti-inflammatory agents would lead to reduced leukocyte recruitment and improved microvascular blood flow in vivo. In transgenic sickle mice, hypoxia-reoxygenation resulted in greater endothelial oxidant production than in control mice. This exaggerated inflammatory response in transgenic mice, characterized by increased leukocyte recruitment and microvascular flow abnormalities, was significantly attenuated by antioxidants (allopurinol, SOD, and catalase). In contrast, control mice exhibited a muted response to antioxidant treatment. In addition, hypoxia-reoxygenation induced activation of NF-\u03baB in transgenic sickle mice but not in control mice. In transgenic sickle mice, sulfasalazine, an inhibitor of NF-\u03baB activation and endothelial activation, attenuated endothelial oxidant generation, as well as NF-\u03baB activation, accompanied by a marked decrease in leukocyte adhesion and improved microvascular blood flow. Thus targeting oxidant generation and\/or NF-\u03baB activation may constitute promising therapeutic approaches in sickle cell disease.<\/jats:p>","DOI":"10.1152\/ajpheart.01150.2003","type":"journal-article","created":{"date-parts":[[2004,3,9]],"date-time":"2004-03-09T01:33:36Z","timestamp":1078796016000},"page":"H293-H301","source":"Crossref","is-referenced-by-count":101,"title":["Anti-inflammatory therapy ameliorates leukocyte adhesion and microvascular flow abnormalities in transgenic sickle mice"],"prefix":"10.1152","volume":"287","author":[{"given":"Dhananjay K.","family":"Kaul","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiao-du","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephana","family":"Choong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John D.","family":"Belcher","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gregory M.","family":"Vercellotti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert P.","family":"Hebbel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"24","reference":[{"key":"R1","doi-asserted-by":"publisher","DOI":"10.1152\/ajpheart.2000.279.2.H791"},{"key":"R2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.221292098"},{"key":"R3","doi-asserted-by":"publisher","DOI":"10.1016\/0026-2862(73)90054-X"},{"key":"R4","doi-asserted-by":"publisher","DOI":"10.1016\/0026-2862(74)90043-0"},{"key":"R5","doi-asserted-by":"publisher","DOI":"10.1097\/00005792-197103000-00002"},{"key":"R6","doi-asserted-by":"crossref","unstructured":"Belcher JD, Bryant CJ, Nguyen J, Bowlin PR, Kielbik MC, Bischof JC, Hebbel RP, and Vercellotti GM.Transgenic sickle mice have vascular inflammation.Blood2003.","DOI":"10.1182\/blood-2002-10-3313"},{"key":"R7","doi-asserted-by":"publisher","DOI":"10.3233\/BIR-1994-31109"},{"key":"R8","doi-asserted-by":"publisher","DOI":"10.1097\/00024382-200211000-00006"},{"key":"R9","doi-asserted-by":"publisher","DOI":"10.1096\/fasebj.9.10.7542214"},{"key":"R10","unstructured":"Conger JDand Weil JV.Abnormal vascular function following ischemia-reperfusion injury.J Investig Med43: 431\u2013442, 1995."},{"key":"R11","unstructured":"Dacie JVand Lewis SM.Practical Hematology.
