PURPOSE End-organ apoptosis is well-described in progressive sepsis and Multiple Organ Dysfunction Syndrome (MODS), especially where platelets accumulate (e.g. spleen and lung). We previously reported an acute sepsis-induced cytotoxic platelet phenotype expressing serine protease granzyme B. We now aim to define the site(s) of and mechanism(s) by which(More)
The immediate early protein tristetraprolin (TTP) is required to prevent inappropriate production of the cytokine TNF-alpha, and is a member of a zinc finger protein family that is associated with RNA binding. TTP expression is induced by TNF-alpha, and evidence indicates that TTP can bind and destabilize the TNF-alpha mRNA. TTP and the closely related(More)
Intestinal ischemia followed by reperfusion leads to local and remote organ injury attributed to inflammatory response during the reperfusion phase. The extent to which ischemia contributes to ischemia/reperfusion injury has not been thoroughly studied. After careful evaluation of intestinal tissue following 30 min of ischemia, we noticed significant local(More)
