"The role of chicken IL-1 beta, IL-6 and TNF-alpha in the occurrence of amyloid arthropathy". Veterinary Research Communications, 32(7), 499-508.0165-73801573-7446https://doi.org/10.1007/s11259-007-9034-6https://link.springer.com/article/10.1007/s11259-007-9034-6http://hdl.handle.net/11452/25481In this study, the roles of IL-1 beta, IL-6 and TNF-alpha in amyloid arthropathic chickens with variable amounts (severe, moderate and mild) of amyloid accumulation were investigated. The presence and the levels of cytokines were evaluated in serum and in joint tissues by using ELISA and immunohistochemistry, respectively. One hundred brown layer chicks were allocated into four groups and intra-articular injections of Freund's adjuvant were used to induce amyloid arthropathy in Groups II, III and IV. Vitamin A in group II, and methylprednisolone in Group IV were added to enhance and to reduce the severity of amyloidosis, respectively. At the end of the study, a positive correlation was observed among the incidence and severity of amyloidosis, the serum amyloid A levels and the IL-1 beta values both in the serum and tissues. Elevation in the tissue TNF-alpha levels in parallel with the severity of amyloidosis has also been noted. As a conclusion, IL-1 beta appears to play an important role in avian AA amyloidosis either alone or in combination with TNF-alpha. Further investigation is needed for understanding the role of the pro-inflammatory cytokines in avian AA amyloidosis.eninfo:eu-repo/semantics/closedAccessAmyloid arthropathyCytokineChickenIL-1 betaIL-6TNF-alphaAvesGallus gallusVeterinary sciencesArticle0002592769000012-s2.0-5274908412049950832718612836Veterinary sciencesSerum Amyloid A Protein; Amyloidosis; Amyloid Enhancing FactorAmyloid a proteinFreund adjuvantInterleukin 1betaInterleukin 6MethylprednisoloneRetinolTumor necrosis factor alphaAmyloidosisAnimal tissueArthropathyArticleBird diseaseBlood analysisChickenControlled studyCorrelation analysisDisease severityEnzyme linked immunosorbent assayImmunohistochemistryIncidenceNonhuman
