IL-21/IL-21R in Autoimmune Diseases
Interleukin-21 (IL-21), the member of the γ-chain-related cytokine family, and its receptor (IL-21R), has been evidenced involving in the immune response, resulting in the development of autoimmune diseases, infectious diseases and tumors. This short communication reviews an overall outline of its genetic variants and expression in autoimmune diseases. It focuses on a series of recent studies t...
متن کاملIFN- regulates IL-21 and IL-21R expression in human NK and T cells
Interleukin (IL)-21 is a T cell-derived cytokine that regulates innate and adaptive immune responses. IL-21 receptor (IL-21R), which is expressed in natural killer (NK) and T cells, is structurally homologous to IL-2R and IL-15R . These receptors also share a common cytokine receptor -chain with IL-4, IL-7, and IL-9. Macrophageor dendritic cell-derived interferon (IFN)/ is a key cytokine in reg...
متن کاملIL 21 R ( interleukin 21 receptor )
The IL21R gene is comprised of 9 exons (+2 alternative first exons), spanning 48.4kb on chromosome 16p11 (Parrish-Novak, 2000). The human IL21R promoter region, contained within nucleotides -789 to +195 (relative to the start of exon 1a) induces the high levels of transcription in reporter assays (Ueda, 2002). A critical SP1 binding site is contained in the region from -80 to -20 and is essenti...
متن کاملUpregulated IL-21 and IL-21 receptor expression is involved in experimental autoimmune uveitis (EAU)
PURPOSE Interleukin (IL)-21 has recently been shown to play a vital role in the development of many autoimmune diseases. Our study is designed to investigate the alteration and possible function of IL-21 in the development of an experimental autoimmune uveitis (EAU) model. METHODS EAU was induced in B10.RIII mice by subcutaneous injection of interphotoreceptor retinoid-binding protein (IRBP) ...
متن کاملIL-21R gene polymorphisms and serum IL-21 levels predict virological response to interferon-based therapy in Asian chronic hepatitis C patients.
BACKGROUND IL-21R polymorphisms have been identified as potential predictors of virological outcomes in Western chronic hepatitis C (CHC) patients receiving interferon-based treatment. We aimed to examine the associations of IL-21R genotypes and serum IL-21 levels with virological responses to interferon-based treatment in Asian CHC patients. METHODS Genomic and clinical data were collected f...
