Il-23 receptor signaling-May 13, 21The IL23 receptor (IL23R) signaling pathway has pleiotropic effects on the differentiation of osteoclasts and osteoblasts, since it can inhibit or stimulate these processes via different pathwaysNov 01, 11Interleukin23 (IL23) is known to play a crucial role in the development and maintenance of T helper 17 cells It has been previously demonstrated that IL17 is involved in experimental Lyme
IL23R IL23R FACS analysis by Parham et al (02) readily detected binding of IL23, but not IL12, to IL23R Signal transduction analysis showed constitutive association of IL23R with JAK2 and liganddependent association with STAT3 (), as well as IL23dependent tyrosine phosphorylation of IL23RNov 17, 17Increasing evidence suggests that the IL‐23 signaling pathway may be involved in the development of autoimmunity and erosive joint damage IL‐23 can act either directly or indirectly on bone forming osteoblasts as well as on bone resorbing osteoclastsDec 22, INTERLEUKIN 23 RECEPTOR;

IL23 signals through the IL23 receptor IL17producing T cells express IL23R, and IL23 plays an important role in sustaining Th17 cell responses in vivo Although one study showed loss of microRNAdependent regulation of one IBDassociated IL23R variant resulting in enhanced protein production, no enhanced IL23 levels have been found so far in AS ( Zwiers et al, 12 )IL23 signaling pathway IL23 plays important role in expanding and maintaining the Th17 cell population, a novel Tcell subset involved in antimicrobial immune response and establishment of many autoimmune diseases 1 IL23 receptor is composed of IL12RB1 and IL23R IL23R associates with JAK2 and in a liganddependent manner with STAT3 2The interleukin 23 (IL23) is a key proinflammatory cytokine in the development of chronic inflammatory diseases, such as psoriasis, inflammatory bowel diseases, multiple sclerosis, or rheumatoid arthritis The pathological consequences of excessive IL23 signaling have been linked to its ability to promote the production of inflammatory mediators, such as IL17, IL22,
In contrast, IL23 signaling is involved in the stabilization and maintenance of Th17 cells, promotes memory T cell activation, and stimulates IL17mediated neutrophil recruitment to sites of infection Although these activities demonstrate that IL12 and IL23 induce different immune responses, both can be characterized as proinflammatoryIncreasing evidence suggests that the IL23 signaling pathway may be involved in the development of autoimmunity and erosive joint damage IL23 can act either directly or indirectly on bone forming osteoblasts as well as on bone resorbing osteoclastsIL23 functions in innate and adaptive immunity and may participate in acute response to infection in peripheral tissues IL23 may be responsible for autoimmune inflammatory diseases and be important for tumorigenesis Tissue specificity Expressed by
Feb 18, 21Feb 18, 21This extracellular receptor specificity is relayed to distinct patterns of intracellular signaling in which IL12 led to phosphorylation of STAT4 with minimal activation of STAT3 while IL23 led to phosphorylation of STAT3 without inducing STAT4 phosphorylation in primary human CD4 T cells (Figures 4B and 4C) The specificity of IL12 and IL23 signaling suggests that p40 plays similar roles in both complexes to recruit IL12Rβ1/Tyk2 and initiate STAT signalingBased on the shared role of the p40/IL12Rβ1 interaction in both the IL12 and IL23 receptor complexes, we targeted this interface to modulate STAT4 signaling in the context of IL12, and STAT3 signaling in the context of IL23, by systematically impairing theMar 23, IL23 receptor is associated with JAK2 and TYK2 that promote STAT3 phosphorylation and activation , and active STAT3 increases the expression of the transcription factor RORγt, which is crucial for IL17 production However, reported data suggest that in addition to the STAT3/RORγt axis, other IL23regulated events are involved in disease development

In addition, IL23 treatment significantly increased the accumulation of CD133 cells and activated the Wnt and Notch signaling pathways in CD133−IL23R ESCC cell lines Consistently, CD133−IL23R cells pretreated with IL23 showed stronger antiapoptosis activity when exposed to radiation and higher survival than untreated groupsRecently Dr Adamopoulos collaborated with Dr Savvides, a structural biologist at the VIB Insitute, Ghent in Belgium to further solve the structure of the IL23 and IL23 receptor complex BothWhile estradiol and progesterone increased IL17A production in Th17 cells by inhibiting Let7fmiRNA expression and increasing IL23 receptor (IL23R) expression, it remained unclear how estrogen signaling through the canonical nuclear receptors, estrogen receptor α (ERα) and/or ERβ, regulated this pathway
