Multiplex cytokine profiling in patients with sepsis.

A major goal for the clinical research in sepsis is mapping the various mediators driving the systemic manifestations of infection. Identifying relevant mediators responsible for the physiological alterations during sepsis may offer diagnostic and therapeutic opportunities. We aimed to explore the novel approach of simultaneously measuring several biomolecules using the multiplex technique and to study its relevance in diagnosing and monitoring septic patients.

Reduced liver injury and cytokine release after transplantation of preconditioned intestines.

Background: The postischemic intestine liberates pro-inflammatory mediators (cytokines, lipopolysaccharide [LPS], free radicals) proportional with the local injury that may trigger a systemic inflammatory response and multi-system organ failure. Previously, intestines from donors receiving Tacrolimus revealed improved morphology and abrogated nuclear factor kappa B (NF-kappaB) activation. Because of its pivotal role in inflammation, we investigated if NF-kappaB intragraft inhibition influences the posttransplant inflammatory response and remote organ injury.

Extracellular survivin up-regulates adhesion molecules on the surface of leukocytes changing their reactivity pattern.

Rheumatoid arthritis (RA) is an autoimmune disease with joints as a principal target of inflammation. We have shown recently that the extracellular expression of the antiapoptotic protein survivin is associated with a destructive course of RA. Here, we address the potential impact of extracellular survivin on peripheral blood leukocytes (PBL).
