Production of interleukin-1 receptor antagonist by human articular chondrocytes
Interleukin-1 receptor antagonist (IL-1Ra) is a natural IL-1 inhibitor possessing anti-inflammatory properties. IL-1Ra is produced as different isoforms, one secreted (sIL-1Ra) and three intracellular (icIL-1Ra1, icIL-1Ra2 and icIL-1Ra3), derived from the same gene. We examined the production of IL-1Ra species by cultured human articular chondrocytes in response to various cytokines. The levels...
متن کاملInterleukin-1 receptor antagonist.
IL-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. Two structural variants of IL-1ra exist: sIL-1ra, a secretory m...
متن کاملAutomation of [18F]fluoroacetaldehyde synthesis: application to a recombinant human interleukin‐1 receptor antagonist (rhIL‐1RA)
[(18) F]Fluoroacetaldehyde is a biocompatible prosthetic group that has been implemented pre-clinically using a semi-automated remotely controlled system. Automation of radiosyntheses permits use of higher levels of [(18) F]fluoride whilst minimising radiochemist exposure and enhancing reproducibility. In order to achieve full-automation of [(18) F]fluoroacetaldehyde peptide radiolabelling, a c...
متن کاملBiological properties of recombinant human monocyte-derived interleukin 1 receptor antagonist.
Human monocytes cultured on adherent IgG produce a specific IL-1 inhibitor that functions as a receptor antagonist (IL-1ra). This molecular has been purified, sequenced, cloned as a cDNA, and expressed in Escherichia coli. Recombinant IL-1ra has 17,000 mol wt and binds to IL-1 receptors on T lymphocytes, synovial cells, and chondrocytes with an affinity nearly equal to that of IL-1. These studi...
متن کاملAnakinra, a recombinant human interleukin-1 receptor antagonist, inhibits apoptosis in experimental acute myocardial infarction.
BACKGROUND Experimental interleukin-1 receptor antagonist gene overexpression has shown that interleukin-1 receptor antagonist is cardioprotective during global cardiac ischemia. The aim of the present study was to test the impact of an exogenous recombinant human interleukin-1 receptor antagonist (anakinra) in experimental acute myocardial infarction. METHODS AND RESULTS Two animal studies w...
