  • 線性度：

    To assess the linearity of the assay, samples were spiked with high concentrations of human adipsin in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

靶點詳情

  • 最新研究進展：
    CFD（Complement factor D）是補體系統中的一種血清蛋白，主要參與剪切促進因子B（Factor B）的激活，從而啟動替代途徑的活化。最新研究表明，CFD在炎癥、自身免疫疾病、感染和腫瘤等多種疾病中都起到了重要作用。例如，CFD可以促進炎癥細胞的浸潤和激活，導致組織損傷和炎癥反應。此外，CFD也參與了腫瘤的生長、侵襲和轉移等過程。
     
  • 功能：
    Factor D cleaves factor B when the latter is complexed with factor C3b, activating the C3bbb complex, which then becomes the C3 convertase of the alternate pathway. Its function is homologous to that of C1s in the classical pathway.
  • 基因功能參考文獻：
    1. MASP-3 is the exclusive pro-factor D activator in resting blood: the lectin and the alternative complement pathways are fundamentally linked. PMID: 27535802
    2. disturbance of reciprocal relationships between adipsin and leptin in obesity is associated with the development of insulin resistance PMID: 28864895
    3. TZDs (pioglitazone, rosiglitazone, and ciglitazone) slow tumor cell growth in vitro and in vivo with decreases in cell proliferation and increases in PPARg and adipsin PMID: 28219679
    4. The strong association of PLIN1, CFD and ADIPOQ genes with adipogenesis prompted authors to study the influence the bone health status as evaluated by quantitative ultrasound (QUS) bone densitometer in a North Indian cohort. Overall, ADIPOQ (rs1501299 and rs3774261) and combined cluster of PLIN1 rs2304796 and rs2304795) and CFD (rs1683563) demonstrated correlation. PMID: 28189761
    5. our findings set up a novel mechanism for FABP4, adipsin and adiponectin through gut microbiota mediating expression in gut Paneth cells. PMID: 26687459
    6. Overall adipsin levels among male asbestos industry workers were significantly higher than among control subjects. PMID: 25840635
    7. Data indicate that a urinary protein, adipsin, was significantly increased in patients with preeclampsia. PMID: 24958499
    8. Study demonstrates that T2DM patients with beta cell failure are deficient in adipsin. PMID: 24995977
    9. Complement factor D (FD) is activated by its substrate through interactions outside the active site which lock the unbound native state into an ordered inactive conformation via the self-inhibitory loop in FD. PMID: 24598742
    10. We demonstrate novel secretion of adipsin and ASP by placental Hofbauer cells. PMID: 23956345
    11. Increased activation of the alternative complement pathway in vitreous was controlled by disease stage and genetic variation in the complement pathway, supporting a role for complement activation in macular degeneration disease pathogenesis. PMID: 22930722
    12. Anti factor D Fab fragment inhibits FD proteolytic function by interfering with macromolecular substrate access rather than by inhibiting FD catalysis. PMID: 22362762
    13. CFD regulates activation of the alternative complement pathway, which is implicated in age related macular degeneration pathogenesis. PMID: 22003108
    14. CFD may not play a major role in the genetic susceptibility to age-related macular degeneration. PMID: 21139680
    15. crystal structure of C3bB at 4 A and complex with factor D at 3.5 A; data show how factor B binding to C3b forms open "activation" state of C3bB; Factor D binds open conformation of factor B through a site distant from the catalytic center PMID: 21205667
    16. As adiponectin and adipsin levels in CSF did not correlate with their levels in plasma, it seems that there could be a secondary intrathecal synthesis of these adipocytokines in multiple sclerosis PMID: 19538214
    17. increased serum levels in patients with seasonal allergic rhinitis PMID: 19699327
