Disease relevance of IL22

 

High impact information on IL22

  • The effect of IL-21-treated epithelial cell supernatants on blood lymphocyte migration was assessed using a chemotaxis assay [6].
  • Interleukin-22, a member of the IL-10 subfamily, induces inflammatory responses in colonic subepithelial myofibroblasts [1].
  • CONCLUSIONS: IL-22 derived from activated T cells acts on SEMFs to elicit expression of proinflammatory cytokines and matrix-degrading molecules indicating proinflammatory/remodeling roles in IBD [1].
  • MAP-kinase inhibitors (PD98059, U0216, and SB202190) significantly reduced IL-22 induction of cytokine secretion [1].
  • 2. We demonstrate that IL-22RA2 binds specifically to IL-22 and neutralizes IL-22-induced proliferation of BaF3 cells expressing IL-22 receptor subunits [7].
 

Chemical compound and disease context of IL22

 

Biological context of IL22

 

Anatomical context of IL22

 

Associations of IL22 with chemical compounds

  • Similar acute phase reactant induction was observed in mouse liver upon IL-TIF injection, and IL-TIF expression was found to be rapidly increased after lipopolysaccharide (LPS) injection, suggesting that this cytokine contributes to the inflammatory response in vivo [2].
  • IL-22 messenger RNA and protein expression are significantly elevated in T cell-mediated hepatitis induced by concanavalin A (ConA) but are less extensively elevated in the carbon tetrachloride-induced liver injury model [13].
  • IL-22 also induced serine phosphorylation of STAT3 on Ser(727) [16].
  • IL-22 treatment of EMT6 tumor-bearing mice lead to a decreased tumor size and a reduced tumor cell proliferation in vivo, as determined by 3'-deoxy-3'-fluorothymidine-positron emission tomography scans [17].
 

Physical interactions of IL22

  • In addition, IL-22 mediates inflammation and binds class II cytokine receptor heterodimers IL-22 RA1/CRF2-4 [3].
 

Enzymatic interactions of IL22

  • Importantly, IL-22 exposure of EMT6 cells resulted in decreased levels of phosphorylated ERK1/2 and AKT protein kinases, indicating an inhibitory effect of IL-22 on signaling pathways promoting cell proliferation [17].
 

Regulatory relationships of IL22

  • The high levels of expression of IL-22R1 observed in epithelial cells of the colon and the ability of IL-22 to upregulate production of acute phase proteins and IL-10 in Colo205 cells, suggest a functional role for IL-22 in intestinal inflammation [11].
  • The aim of this study is to identify potential target cells and associated biological activity of IL-22 by identifying cell types that specifically express high levels of IL-22R1 as the expression of IL-10R2 is ubiquitous [11].
  • Further analyses, by real time quantitative PCR, on a panel of chemokines and immune function related genes revealed that IL-22 induced expression of the acute phase proteins alpha-Antichymotrypsin and Serum Amyloid A, as well as IL-10 mRNA and protein production by Colo205 [11].
  • Thus, the soluble receptor designated IL-22BP inhibits IL-22 activity by binding IL-22 and blocking its interaction with the cell surface IL-22R complex [18].
  • In these cells, IL-22 activates biological activities specific for IFN-gamma, such as up-regulation of MHC class I Ag expression [18].
 

Other interactions of IL22

  • However, in hamster cells both chains, CRF2-9 and IL-10R2, must be expressed to assemble the functional IL-TIF receptor complex [10].
  • Structural differences between these two cytokines, revealed by the crystallographic studies, clearly indicate that, while a homodimer of IL-10 is required for signaling, hIL-22 most probably interacts with its receptor as a monomer [19].
  • These data demonstrate that IL-19, IL-20 and IL-22 may participate in T cell-mediated diseases by distinct regulation of T cell cytokine profiles [20].
  • Investigation of malaria susceptibility determinants in the IFNG/IL26/IL22 genomic region [12].
  • Transcripts of IL-19, IL-20, and IL-22 from monocytes were analyzed [21].
