產品詳情

  • 產品描述：
    犬腫瘤壞死因子α (TNF-α )酶聯免疫試劑盒（CSB-E11737c）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的TNF含量。TNF即腫瘤壞死因子，是一種重要的細胞因子。它在炎癥反應、免疫調節等生理病理過程中起關鍵作用。研究機制上，TNF可通過與受體結合，激活多條信號通路，參與細胞存活、凋亡、增殖等調控，其異常與多種疾病如自身免疫病、腫瘤等相關。試劑盒檢測范圍為0.156 ng/mL-10 ng/mL，該產品廣泛應用于動物模型研究，如炎癥性疾病機制探索、免疫抑制劑藥效評估、疫苗免疫原性分析等領域，為犬類基礎醫學研究和生物標志物開發提供可靠工具。本品僅用于科研，不用于臨床診斷，產品具體參數及操作步驟詳見產品說明書。

靶點詳情

  • 功能：
    Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of cachexia, Under certain conditions it can stimulate cell proliferation and induce cell differentiation. Induces insulin resistance in adipocytes via inhibition of insulin-induced IRS1 tyrosine phosphorylation and insulin-induced glucose uptake. Induces GKAP42 protein degradation in adipocytes which is partially responsible for TNF-induced insulin resistance. Plays a role in angiogenesis by inducing VEGF production synergistically with IL1B and IL6.; The TNF intracellular domain (ICD) form induces IL12 production in dendritic cells.

    1. two SNPs of the TNF gene are associated with obesity in Labrador dogs PMID: 26692319
    2. Fatal outcome from pulmonary hemorrhages in dogs with leptospirosis was associated with low TNF-alpha, high IL-1beta, and high iNOS expression. PMID: 26824356
    3. This diminished TNF-alpha, IL-6 and iNOS expression, and NO production was in parallel to the respective decreased NF-kappaB p65 protein nuclear translocation in the LPS-activated canine PBMCs pretreated with 25 microM and 50 microM propofol. PMID: 25312048
    4. Tumour necrosis factor (TNF)-alpha expression was observed in vascular endothelial cells in both neoplastic and normal kidney. PMID: 22300704
    5. The observed HMGB1 release kinetics showed a clearly time-dependent manner with a peak release 24h after TNF-alpha stimulation, while stimulation with IFN-gamma had only small effects on the HMGB1 release. PMID: 22154216
    6. the TNF-alpha-induced activation of the ERK/GEF-H1/RhoA pathway in tubular cells is mediated through Src- and TACE-dependent EGFR activation. PMID: 21212278
    7. The replication characteristics of H3N8 influenza virus and its effects on protein expression of canine alveolar macrophages are reported; only TNF-alpha levels were significantly increased 12 h after inoculation. PMID: 19605916

    10. findings suggest that susceptibility to Anal furunculosis in German Shepherd dogs is primarily associated with DLA-DRB1*00101 and any association with the Tumor Necrosis Factor-alpha locus is secondary and is because of linkage disequilibrium . PMID: 19254251
    11. the ERK/GEF-H1/Rho/Rho kinase/phospho-MLC pathway is the mechanism mediating TNF-alpha-induced elevation of tubular epithelial permeability, which in turn might contribute to kidney injury PMID: 19261619
    12. The usefulness of HSP27, HSP70, and TNF-alpha as biological markers for canine skin diseases was studied. PMID: 19578946
