Horse Interleukin 6(IL-6)ELISA Kit

Cytokine with a wide variety of biological functions in immunity, tissue regeneration, and metabolism. Binds to IL6R, then the complex associates to the signaling subunit IL6ST/gp130 to trigger the intracellular IL6-signaling pathway. The interaction with the membrane-bound IL6R and IL6ST stimulates 'classic signaling', whereas the binding of IL6 and soluble IL6R to IL6ST stimulates 'trans-signaling'. Alternatively, 'cluster signaling' occurs when membrane-bound IL6:IL6R complexes on transmitter cells activate IL6ST receptors on neighboring receiver cells.; IL6 is a potent inducer of the acute phase response. Rapid production of IL6 contributes to host defense during infection and tissue injury, but excessive IL6 synthesis is involved in disease pathology. In the innate immune response, is synthesized by myeloid cells, such as macrophages and dendritic cells, upon recognition of pathogens through toll-like receptors (TLRs) at the site of infection or tissue injury. In the adaptive immune response, is required for the differentiation of B cells into immunoglobulin-secreting cells. Plays a major role in the differentiation of CD4(+) T cell subsets. Essential factor for the development of T follicular helper (Tfh) cells that are required for the induction of germinal-center formation. Required to drive naive CD4(+) T cells to the Th17 lineage. Also required for proliferation of myeloma cells and the survival of plasmablast cells.; Acts as an essential factor in bone homeostasis and on vessels directly or indirectly by induction of VEGF, resulting in increased angiogenesis activity and vascular permeability. Induces, through 'trans-signaling' and synergistically with IL1B and TNF, the production of VEGF. Involved in metabolic controls, is discharged into the bloodstream after muscle contraction increasing lipolysis and improving insulin resistance. 'Trans-signaling' in central nervous system also regulates energy and glucose homeostasis. Mediates, through GLP-1, crosstalk between insulin-sensitive tissues, intestinal L cells and pancreatic islets to adapt to changes in insulin demand. Also acts as a myokine. Plays a protective role during liver injury, being required for maintenance of tissue regeneration. Also has a pivotal role in iron metabolism by regulating HAMP/hepcidin expression upon inflammation or bacterial infection. Through activation of IL6ST-YAP-NOTCH pathway, induces inflammation-induced epithelial regeneration.

1. These data suggest that IL-6 may play a key role in equine metabolic syndrome (EMS), and that pro-inflammatory cytokines levels in serum may serve as an additional tool for diagnosing EMS. PMID: 25269712
2. IL-6 stimulation decreased chondrocyte expression of the canonical Wnt signaling pathway transactivator beta-catenin, induced expression of inhibitors of the Wnt pathway, and increased expression of GDF-5. PMID: 24471749
3. study shows that IL-6 is rapidly induced in BAL-cells of airway-compromised horses in response to adenosine exposure, probably through A2BAR activation and that this effect can be modulated by A2AAR PMID: 21496101
4. Our data show the presence of a polymorphism downstream of the equine IL-6 gene that is associated with the basal Cu:Zn ratio in horses independent of breed. PMID: 21330167
5. Expression levels of IL-6 are significantly increased in peripheral blood mononuclear cells from trained horses compared to sedentary animals. PMID: 21255427
6. Failure of passive transfer may directly influence the serum IL-6 concentration in septic foals. Neither serum IL-6 nor IL-10 alone, were useful diagnostic indices of sepsis in equine neonates. PMID: 19501415
7. The contribution of bronchial epithelium to airway inflammation, with focus on mRNA and protein expression of IL-6, IL-10 and TNF-alpha, in horses with recurrent airway obstruction during exacerbation and in remission is reported. PMID: 18294392
8. The effects of semen extender and seminal plasma on the expression of inflammatory modulators in the endometrium of mares are reported. PMID: 18584861
