Disease relevance of IL20RB

 

High impact information on IL20RB

  • IL-23 stimulates epidermal hyperplasia via TNF and IL-20R2-dependent mechanisms with implications for psoriasis pathogenesis [1].
  • Here, we show that mda-7 and IL-19 bind to the previously described IL-20R complex, composed by cytokine receptor family 2-8/IL-20Ralpha and DIRS1/IL-20Rbeta (type I IL-20R) [2].
  • The presence of lambda-recombinase-like genes in DIRS1 elements also accounts for the lack of target-site duplications for these elements and may be related to the unusual structures of their terminal repeats [3].
  • We also present evidence for the existence of DIRS1-like sequences in the human genome [3].
  • IFNalpha/beta enhance the secretion and expression of IL-6 and IL-10 during the response to LPS, but also the up-regulation of IL-20R2 expression [4].
 

Biological context of IL20RB

  • PAT and kangaroo both contain split direct repeat (SDR) termini, and here we show that DIRS-1 and DrDIRS1 elements contain terminal features structurally related to SDRs [5].
 

Anatomical context of IL20RB

  • In addition, there is no apparent correlation between patterns of expression of IL-20R1, IL-20R2, and IL-22R mRNA and susceptibility to Ad.mda-7 in different cell lines [6].
  • BACKGROUND: Interleukin (IL)-19, a member of the IL-10 family, signals through the IL-20R1/IL-20R2 heterodimer, which is shown to be involved in abnormal keratinocyte differentiation and proliferation [7].
  • The expression of IL-20R1 and IL-20R2 was also upregulated by human umbilical vein endothelial cells in response to hypoxic treatment [8].
 

Associations of IL20RB with chemical compounds

 

Physical interactions of IL20RB

  • The absence of either R1 chain for the two types of receptor complexes for these cytokines (IL-20R1/IL-20R2 and IL-22R1/IL-20R2) on immune cells implies that they cannot act on these cells [10].
 

Regulatory relationships of IL20RB

 

Other interactions of IL20RB

  • It has also been shown that in the case of IL-19 and IL-20, IL-20R2 rather than IL-20R1 is a high-affinity receptor chain [12].
