Associations of Il6ra with chemical compounds

  • The function of IL-6R in the luminal and glandular epithelium might be different from that in the stroma during the implantation period [15].
  • There was no correlation between the signal strength of the IL-6R mRNA and the serum concentrations of progesterone and 17beta-estradiol, which show a monophasic rise in the non-pregnant sexual cycle [15].
  • We report that 17beta-estradiol or dihydrotestosterone in vitro decreased the abundance of the gp80 mRNA as well as the mRNA of the signal-transducing subunit of the IL-6 receptor (gp130) in cells of the bone marrow stromal/osteoblastic lineage, and also decreased gp130 protein levels [9].
  • These effects were suppressed by adding neutralizing antibodies against IL-1alpha or IL-6R and were totally abolished by adding nonsteroidal antiinflammatory drugs, such as indomethacin and a selective cyclooxygenase-2 (COX-2) inhibitor (NS398) [16].
  • Parallel analyses, using CD34(+)Lin(-) cells derived from murine ES cell cultures, showed no apparent expression of flt3, integrin alphaL, or IL-6 receptor, whereas corresponding cell preparations isolated from mouse BM expressed high levels of all of these genes [17].
 

Physical interactions of Il6ra

  • In contrast, the IL-6/IL-6R complexes have a higher inflammatory potential [18].
 

Regulatory relationships of Il6ra

  • Interleukin-6-induced IMCE cell proliferation was blocked by the addition of a neutralizing anti-IL-6R antibody [8].
  • In both strains, IL-6R was induced in CD4+ or CD8+ thymocytes after 2 days of culture, suggesting that CD4+ thymocytes in MRL/lpr have a potential to express IL-6R [19].
 

Other interactions of Il6ra

  • A soluble form of IL-6R (sIL-6R), which lacks transmembrane and cytoplasmic regions, retains the ability to bind IL-6 and signal through gp130 [20].
  • Cytokine stimulation of R1 and R2 cells induced cell cycle progression with elevated or induced expression of c-kit, c-fms, IL-2R, and IL-6R [21].
  • Antibodies neutralising interleukin (IL)-1alpha, IL-1beta, soluble IL-6 receptor, IL-17, or tumour necrosis factor-alpha, when added to individual SFs, only occasionally decreased the bone-resorbing activity [22].
  • The new receptor, named NR1, was most similar in sequence and predicted structure to the alpha-chain of the IL-6 receptor and mRNA was expressed in the 3T3-L1 pre-adipocytic cell line and in a range of primary tissues [23].
  • Expression of either dominant negative protein abolished osteoclast formation stimulated by IL-6 + soluble IL-6 receptor, oncostatin M, or IL-1 but not by parathyroid hormone or 1,25-dihydroxyvitamin D3 [24].
 

Analytical, diagnostic and therapeutic context of Il6ra

  • The increase in IL-6 and IL-6R was confirmed by western blotting using epidermal homogenates and was partially prevented by occlusion immediately after barrier disruption [11].
  • During the formation of tartrate-resistant acid phosphatase (TRAP)-positive multinucleated cells (MNCs), IL-6R and gp130 expression in the mononuclear cells, stromal cells, and TRAP-positive MNCs were quantitated, using a laser cytometer with a fluorescence confocal microscopy [14].
  • The lung fibroblasts expressed IL-6 receptors on their surface as determined by flow cytometry using a rat anti-mouse IL-6 receptor antibody (15A7).(ABSTRACT TRUNCATED AT 250 WORDS)[25]
  • Thus, IL6-PE4E may be useful for ex vivo purging of IL-6R+ leukemic cells in an autologous bone marrow transplantation setting and possibly for therapy of residual, chemotherapy-resistant disease [26].
  • This reduction in bioactivity was shown to be due to a decreased capacity of the mutant protein to trigger IL-6 receptor-alpha-chain-dependent binding to the IL-6 signal transducer, gp130 [27].
