Interleukin-1 (IL-1) and tumor necrosis factor α (TNF-α) play key proinflammatory roles in a variety of human diseases, including rheumatoid arthritis (RA). IL-1 receptor antagonist (IL-1Ra) is a naturally occurring structural variant of IL-1 that

IL-1R antagonist (IL-1Ra) is a competitive inhibitor of the binding of IL-1 to IL-1R. IL-1Ra refers to two different proteins derived from the same gene by alternate splicing of two different first exons. One protein contains a leader sequence and is

These studies have examined the binding of the three IL-1 ligands, IL-1 alpha, IL-1 beta, and IL-1 receptor antagonist (IL-1 ra), to soluble forms of types I and II IL-1Rs (sIL-1RI and sIL-1RII). This interaction was measured in direct binding experi

Expression of the IL-1 receptor antagonist (IL-1ra) can be induced by treatment of monocytes and macrophages with LPS. We have previously demonstrated that the most proximal 294 bp of the human IL-1ra promoter are sufficient for full basal activity a

To study the molecular mechanisms involved in transcriptional regulation of the human IL-1R antagonist (IL-1ra) we have isolated 1680-bp of 5'-flanking region DNA from the IL-1ra gene. This region of DNA was sequenced and cloned into the luciferase e

The objective of these studies was to characterize the IL-1 inhibitory activity present in normal and psoriatic epidermis from clinically stable lesions. Fractionation of normal epidermal cytosol on a molecular sizing column failed to reveal the pres

The expression of cell surface nuclear Ag was studied by examining the binding of anti-histone mAb to viable human peripheral blood cells. Freshly isolated cells showed no binding of these mAb. However, in vitro culture in the presence of LPS induced

Preformed soluble immune complexes injected into rabbits or rhesus monkeys showed similar characteristics of disappearance from circulation. Complexes made with intact gammaG-antibodies and exceeding the Ag(2)Ab(2) lattice formation were rapidly remo

The objective of these experiments was to evaluate the production of IL-1ra, a specific receptor antagonist of IL-1, by human in vitro-derived macrophages, a model for differentiated macrophages. IL-1ra protein levels in supernatants and lysates of c

Human monocytes may synthesize simultaneously both the agonist IL-1 beta and a specific receptor antagonist of IL-1 (IL-1ra). These studies examined whether monocyte production of these two structurally related cytokines was regulated differently. IL
