Consequently, bacteremia levels were reduced, hypotension and lung lesions were prevented, and the survival rate increased from approximately 13% to approximately 80%. Even when treatment was delayed (6 h after CLP), a highly significant reduction in mortality compared with untreated mice was observed. Moreover, H2S pretreatment prevented the down-regulation of CXCR2 and l-selectin and the up-regulation of CD11b and G protein\u2013coupled receptor kinase 2 in neutrophils during sepsis. H2S also prevented the reduction of intercellular adhesion molecule\u20131 expression in the endothelium of the mesenteric microcirculation in severe sepsis. Confirming the critical role of H2S on sepsis outcome, pretreatment with dl-propargylglycine (a CSE inhibitor) inhibited neutrophil migration to the infectious focus, enhanced lung lesions, and induced high mortality in mice subjected to nonsevere sepsis (from 0 to \u223c80%). The beneficial effects of H2S were blocked by glibenclamide (a ATP-dependent K+ channel blocker).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>These results showed that H2S restores neutrophil migration to the infectious focus and improves survival outcome in severe sepsis by an ATP-dependent K+ channel\u2013dependent mechanism.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1164\/rccm.200907-1145oc","type":"journal-article","created":{"date-parts":[[2010,3,25]],"date-time":"2010-03-25T21:53:15Z","timestamp":1269553995000},"page":"360-368","source":"Crossref","is-referenced-by-count":90,"title":["Hydrogen Sulfide Improves Neutrophil Migration and Survival in Sepsis via K+ATP Channel Activation"],"prefix":"10.1093","volume":"182","author":[{"given":"Fernando","family":"Spiller","sequence":"first","affiliation":[{"name":"Department of Pharmacology and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria I.
