Interleukin-1 Receptor Antagonist Protein: Solution Secondary Structure from NOE's and 1H« and 13C« Chemical Shifts
Inter leukinla and interleukin-ip are two polypeptides which share a significant number of inflammatory, immunological and pathological properties (for a review see [1]). Importantly, these dissimilar 17 kDa proteins bind to two classes of interleukin-1 receptors, resulting in the mediation of several immune and inflammatory responses and in the induction of a variety of biological changes in n...
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 کاملProduction 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 کاملHuman interleukin-1 receptor antagonist is expressed in liver.
Using PCR and Northern blot analysis, an IL-1 receptor antagonist specific transcript was amplified from HepG2- and liver mRNA. cDNA clones coding for IL-1 receptor antagonist were isolated from a liver cDNA library and sequence comparison revealed complete identity with the secreted, monocytic form of IL-1 receptor antagonist.
متن کاملPhysiologic role of interleukin-1 receptor antagonist
Recent studies have described the spontaneous development of arthritis or vasculitis in IL-1 receptor antagonist (IL-1Ra) knockout mice bred on specific and different genetic backgrounds. The levels of both secreted and intracellular isoforms of IL-1Ra produced in the rheumatoid joint or in the arterial wall may not be adequate to effectively inhibit the excess amounts of locally produced IL-1....
