  • interleukin family
  • IL-4/IL-13 family
  • CATEGORY immunity/defense , signaling cytokine
    basic FUNCTION
  • important switch factor directing Ig-E synthesis
  • acting as an immunoregulatory and effector cytokine in allergic diseases such as bronchial asthma
  • synergizing with IL2 in regulating interferon-gamma synthesis
  • may be critical in regulating inflammatory and immune responses
  • involved in several stages of B-cell maturation and differentiation
  • up-regulating CD23 and MHC class II expression
  • promoting IgE isotype switching of B cells
  • down-regulating macrophage activity
  • inhibiting the production of pro-inflammatory cytokines and chemokines
  • triggers microglial NADPH oxidase-derived oxidative stress, leading to the degeneration of hippocampal neurons, as occurs in cases of Alzheimer disease
  • inhibition of matrix metalloproteinas-3 (MMP-3) synthetis in fibroblasts
  • induce the death of activated microglia
  • involved in excessive deposition of extracellular matrix (EMC) proteins in giant papillae
  • IL10 and IL13 play important roles in Th2 cell differentiation and production of autoantibodies in patients with (SLE)
  • central role for the IL13/IL13RA1 pathway in the regulation of intestinal epithelial cell Cl(-) secretion via up-regulation of CFTR, suggesting an important role for this pathway in secretory diarrhea
  • induces phosphorylation of Src Tyrosine Kinase in primary monocytes
  • induces HCK tyrosine phosphorylation in alternatively activated monocytes/macrophages, suggesting that HCK may be involved in IL13 signal transduction in monocytes
  • IL4 and IL13 prime the migrational response of haemopoietic progenitor cells to CXCL12 by enhancing the incorporation of CXCR4 into lipid rafts
  • central mediator of airway hyperresponsiveness and mucus expression, both hallmarks of asthma
  • IL13 and IL4R may play an important role in the etiology of renal cell carcinoma
  • IL13 and IL4 can uniquely affect the expression of particular genes such as DUSP1 and TIMP33 and do so through different Jaks
  • CELLULAR PROCESS cell migration & motility
    text cell motility
    signaling signal transduction
    a component
    small molecule
  • IL4 receptor alpha chain
  • IL4, IL9, IL13 may increase CLCA1 expression in cystic fibrosis but may not have a significant effect on mucus expression
  • CCL5 may contribute to modulation of I-13 production and F2R expression in mast cells, through which participates in the mast cell related inflammation
  • novel role of IL4/IL13-induced DUOX1 expression in making a positive feedback loop for IL4/IL13 signaling in keratinocytes
  • inducing repression of STAT6 inhibited expression of SPDEF and MUC5AC
  • CREB1 gene silencing decreased IL13-induced transcription of eotaxin-3 (CCL26)
  • SRC activity is required for IL13-induced STAT1 and STAT3 Ser-727 phosphorylation
  • thyroid hydrogen peroxide production is enhanced by the Th2 cytokines, IL4 and IL13, through increased expression of the DUOX2 and its maturation factor DUOXA2
  • TYK2 controls STAT1 and STAT6 activation in response to IL13 stimulation
  • ITGAM regulates IL13 activity in macrophages by directly interacting with IL13RA1
  • autophagy regulates DUOX1 localization and superoxide production in airway epithelial cells during chronic IL13 stimulation
  • cell & other
    activated by PDGFA that activates the proximal 980-bp region of the IL13 promoter
    oxidant signaling (activates IL13 gene transcription in lung smooth muscle cells and this signaling mechanism regulates cell growth)
