OBJECTIVES To determine the effect of severe sepsis on monocyte tumor necrosis factor-α-converting enzyme baseline and inducible activity profiles. DESIGN Observational clinical study. SETTING Mixed surgical/medical teaching hospital ICU. PATIENTS Sixteen patients with severe sepsis, 15 healthy volunteers, and eight critically ill patients with noninfectious systemic inflammatory response...

We have studied the role of prostaglandin E2 on the modulation of tumor necrosis factor by immunologically elicited and lipopolysaccharide treated murine macrophages. Indomethacin, a potent inhibitor of prostaglandin E2 production, caused a dose dependent augmentation of lipopolysaccharide induced tumor necrosis factor production (2-3 fold at 10(-7) molar). Tumor necrosis factor was released in...

background:  new discoveries about the pathophysiology changed the concept that all forms of osteoarthritis are alike; this lead to the delineation of different phenotypes such as age, trauma or obese related forms. we aim to compare soluble mediator profiles in primary knee and posttraumatic wrist osteoarthritis. based on the general faster progression rate of wrist osteoarthritis, we hypothes...

TNF-resistant lines of L cells can be derived from TNF-sensitive populations by repeated exposure to TNF, and these resistant L cells, in contrast to sensitive L cells and other types of cells, lack demonstrable cell surface receptors for TNF. We have now found that TNF-resistant L cells produce a factor that is cytotoxic for L cells and has the following distinguishing characteristics of mouse...

Background: Concentration of tumor necrosis factor alpha (TNF-alpha) might be useful in selecting patients with paroxysmal atrial fibrillation (PAF) who will benefit the most from pulmonary vein isolation.

OBJECTIVES We determined whether tumor necrosis factor-alpha-converting enzyme (TACE) is expressed with tumor necrosis factor-alpha (TNF-alpha) in myocarditis. BACKGROUND Tumor necrosis factor-alpha-converting enzyme, which has recently been identified as belonging to the family of metalloproteinase disintegrin proteins, is responsible for the conversion of TNF-alpha precursor to its mature f...
