This paper presents evidence to suggest that interleukin-1 alpha as a complex with its receptor is able to express DNA binding activity. Both the interleukin-1/receptor complex and the interleukin-1 receptor appear to be able to bind to DNA, however interleukin-1 on its own showed no binding activity. Interleukin-1 was found to be internalised into the

Journal of Endocrinology, 1997
Abstract Interleukin-1 (IL-1) is a multifunctional cytokine with profound effects on ovarian function. The effects of IL-1 on ovarian steroidogenesis have been demonstrated in several species. IL-1 mRNA levels are increased in the thecal layer of the ovulating follicle and IL-1β has been shown to induce ovulations in vitro.

Blocking interleukin-1 receptors
International Journal of Clinical & Laboratory Research, 1994During inflammation, injury, immunological challenge or infection, interleukin-1 appears to mediate, in part, the pathogenesis, of disease. Most studies on interleukin-1 are derived from experiments in which bacterial products, such as endotoxins from Gram-negative bacteria or exotoxins from Gram-positive organisms, are used to stimulate macrophagic ...

Regulation of bovine interleukin-1 receptors
Veterinary Immunology and Immunopathology, 1998Interleukin-1 is a key player in inflammation and the immune response. The interleukin-1 family consists of three ligands (IL-1 alpha, IL-1 beta, and the IL-1 receptor antagonist) and two receptors (IL-1RI and IL-1RII). Previous studies suggest a dynamic relationship among these receptors and ligands that regulates the magnitude and extent of IL-1 ...

Interleukin-1 receptor antagonist activity of a human interleukin-1 inhibitor
Nature, 1990Three interleukin-1 inhibitors have been purified to homogeneity from medium conditioned by human monocytes. Partial sequence analysis and digestion with N-glycanase indicate that these are glycosylation forms of a single protein. The protein binds to the interleukin-1 receptor but has no interleukin-1-like activity, even at very high concentrations ...

Expression of interleukin-1 and interleukin-1 receptor antagonists in endometrial cancer
Gynecologic Oncology, 1991The cytokine interleukin-1 (IL-1) can inhibit growth of breast cancer cells in culture and promote cellular differentiation in synergism with other growth factors. A secreted IL-1 receptor antagonist (sIL-1ra) has been described and an intracellular version (icIL-1ra) has been cloned; both antagonists block IL-1-dependent responses.

Interleukin-1 Receptor Antagonist
1993IL-1ra is the first described naturally occurring receptor antagonist of any cytokine or hormone-like molecule. IL-1ra is a member of the IL-1 family by three criteria: amino acid sequence homology of 26 to 30% to IL-1 beta and 19% to IL-1 alpha; similarities in gene structure; and common gene localization to human chromosome 2q14.

Interleukin‐1 and interleukin‐1 receptor antagonist in inflammatory bowel disease.
Alimentary Pharmacology & Therapeutics, 1996Ulcerative colitis (UC) and Crohn's disease (CD) are immunologically mediated disorders characterized by a chronic, relapsing inflammatory response. Elevation of several cytokines, with important immunoregulatory and proinflammatory activities have been demonstrated during active inflammatory bowel disease (IBD).

Endogenous Interleukin-1 Receptor Antagonist is Neuroprotective
Biochemical and Biophysical Research Communications, 1997Interleukin-1 (IL-1) has been implicated in chronic and acute cerebral neuropathologies. IL-1 receptor antagonist (IL-1ra), a naturally occurring protein that binds to IL-1 receptors without inducing signal transduction, blocks several actions of IL-1. IL-1ra acts at the local level and it also circulates in the bloodstream.

Interleukin-1 and Interleukin-1 Receptor Antagonist in Systemic Lupus Erythematosus
Immunological Investigations, 1997Interleukin-1 (IL-1) is thought to play an important role in the immunopathology of systemic lupus erythematosus (SLE). IL-1 receptor antagonist (IL-1ra) exhibits a dose-responsive inhibition of IL-1 effects, and Fcr receptors play a key role in IL-1ra production.
