Numerous reports have demonstrated that interleukin-1 β (IL-1β) is a potent secretagogue for adrenocorticotropin (ACTH) and that IL-1α appears to be considerably less efficacious. To clarify apparent differences in the potency of IL- 1α vs. -β on ACTH secretion from a functional perspective, the IL-1 receptor antagonist protein, IRAP, was utilized ...

Recombinant interleukin-1 receptor antagonist protein (rlRAP, 0.5 mg/kg) administered intraperitoneally in guinea pigs one hour before primary and booster parenteral sensitization (1 ml) by cow milk, led to a reduced immunoglobulin E (IgE) production, as displayed by a passive cutaneous anaphylaxis test.

Abstract The purpose of the studies described here was to test the hypothesis that overexpression of the human interleukin-1 receptor antagonist (IL-1ra) in the distal airway epithelia of mice would result in amelioration of the inflammatory effects of IL-1α.

An interleukin 1 (IL-1) inhibitor was detected in the culture supernatant of mouse epidermal sheet which had been irradiated with middle-wavelength ultraviolet (UVB) either in vitro or in vivo. Properties of the IL-1 inhibitor were consistent with those of IL-1 receptor antagonist (IL-1ra), i.e., approximate molecular size of 17 kDa by gel filtration ...

1. The role of interleukin-1 (IL-1) in sepsis-induced muscle proteolysis was assessed by treating septic rats with recombinant IL-1 receptor antagonist (rIL-1ra). 2. In initial experiments, we tested the effectiveness of IL-1ra in preventing muscle proteolysis induced by administration of IL-1. 3.

Human interleukin 1 receptor antagonist protein (IRAP) is a specific antagonist of interleukin 1 (IL-1) action in both in vitro and in vivo experimental models. Presently, the significance of this protein in human pathophysiology is unknown. In the present study, monoclonal antibodies against IRAP were prepared and used to demonstrate IRAP expression ...

Sustained release or high levels of interleukin-1 (IL-1) and/or tumor necrosis factor (TNF), as observed after endotoxin challenge, can produce a variety of toxicities. Naturally occurring inhibitors to IL-1 and TNF, IL-1 receptor antagonist (IL-1ra) and soluble TNF receptor forms, have been detected.

Interleukin-8 (IL-8) is a neutrophil and lymphocyte chemoattractant and activator that may play an important role in mediating events at sites of inflammation. IL-8 is produced by many cell types in response to a variety of inducers, including interleukin-1 (IL-1).

Recombinant human interleukin-1 receptor antagonist was expressed in E. coli as an insoluble inclusion body. The inclusion body was dissolved in the 8 M urea and then the solution was diluted untill the concentration of urea became 2 M. By ion exchange chromatography the protein in the solution of 2 M urea was refolded and purified.
