Epstein-Barr virus (EBV) attachment to primary B cells initiates entry. Although CD21 is the only known receptor for EBVgp350/220, a recent report documents EBV-infected from patient genetically deficient in CD21. On normal resting cells, forms two membrane complexes: one with CD19 and another CD35. Whereas CD21/CD19 complex widely retained on immortalized cell tumor lines, related complement-regulatory protein CD35 lost. To determine role(s) of initial infection, we transduced CD21-negative...

Gut commensal bacteria play important roles in the development and homeostasis of intestinal immunity. However, role gut commensals ischemia/reperfusion (I/R) injury is unclear. To determine IR injury, we depleted microbiota with a broad-spectrum antibiotic cocktail performed mesenteric I/R (M I/R). First, confirmed that treatment completely diminished size secondary lymphoid tissues such as Peyer's patches. We next found attenuated following M I/R. Depletion reduced expression Toll-like...

Abstract Intestinal ischemia followed by reperfusion leads to local and remote organ injury attributed inflammatory response during the phase. The extent which contributes ischemia/reperfusion has not been thoroughly studied. After careful evaluation of intestinal tissue following 30 min ischemia, we noticed significant mucosal in wild-type mice. This was drastically reduced C3-deficient mice, suggesting C3 involvement. Depletion circulating complement with cobra venom factor eliminated, as...

Egg shells are poultry industry byproducts with potential for use in various biological and agricultural applications. We have been interested the membranes underlying calcareous shell as a feed supplement, which showed to improve immunity performance of post hatch poultry. Therefore, determine their protein peptide profiles, we extracted egg (ESM) from fresh unfertilized eggs methanol guanidine hydrochloride (GdHCl) obtain soluble proteins analysis by mass spectrometry. The extract was...

Inflammation and vascular injury triggered by ischemia/reperfusion (I/R) represent a leading cause of morbidity mortality in number clinical settings. Wnt its homolog partners R-spondins, addition to regulating embryonic development have recently been demonstrated serve as wound-healing agents inflammation-associated conditions. Here we ask whether R-spondins could prevent tissue damage ischemic disorders thus investigate the role R-spondin3 (R-spo3) mouse model mesenteric I/R. We...

Objective: Complement system is activated in patients with trauma. Although complement activation presumed to contribute organ damage and constitutional symptoms, little known about the involved mechanisms. Because components may deposit on RBCs, we asked whether deposits surface of RBC trauma such deposition alters function. Design: A prospective experimental study. Setting: Research laboratory. Subjects: Blood samples collected from 42 21 healthy donors. Intervention: None. Measurements...

The robust inflammatory response that occurs during ischemia reperfusion (IR) injury recruits factors from both the innate and adaptive immune systems. However contribution of platelets their products such as Platelet Factor 4 (PF4; CXCL4), pathogenesis IR has not been thoroughly investigated. We show a deficiency in PF4 protects mice local remote tissue damage after 30 minutes mesenteric 3 hours PF4-/- compared to control B6 mice. This protection was independent Ig or complement deposition...

Ischemia-reperfusion (I/R) injury is a leading cause of morbidity and mortality. A functional role for platelets in tissue damage after mesenteric I/R largely unknown. The hypothesis that local remote are platelet dependent was tested. Using murine model, we demonstrate orchestrate lung follows also contribute, albeit to lesser degree, villi damage. While delayed compared with damage, it increased over time characterized by accumulation the pulmonary vasculature early, followed alveolar...

Several innate and adaptive immune cell types participate in ischemia/reperfusion induced tissue injury. Amongst them, platelets have received little attention as contributors the process of damage after ischemia reperfusion (I/R) It is currently unknown whether through immunologically important molecules including, CD40 when activated, CD154 (CD40L), pathogenesis I/R We hypothesized that constitutive expression activation-induced on mediate local mesenteric remote lung Wild type (WT;...
