基因功能参考文献:
- Haemophilic animals (F8(-/-) mice) fed a high fat/fructose diet are highly prone to hepatic steatosis and thrombocytopenia. PMID: 29656466
- CD32 blockade suppresses the FVIII-specific recall response by two ways: i) increasing apoptosis of FVIII-specific memory B-cells and ii) disturbing FVIII-specific T cell response by modulating presentation of rhFVIII to CD4(+) T cells. PMID: 28492697
- Type 2N von Willebrand disease variants were associated with decreased VWF secretion and impaired factor VIII binding/stability. PMID: 28581694
- Cytokine release was quantified from FVIII(-/-) splenocytes restimulated with FVIII in the absence or presence of different anti-FcgammaRIIB (CD32) Antibodies (anti-CD32 mAbs) over 6 days. PMID: 28561280
- results revealed localized vascular expression of FVIII and von Willebrand factor and identified lymphatic endothelial cell as a major cellular source of FVIII in extrahepatic tissues. PMID: 27207787
- the results indicate that residues in the C1 and/or C2 domains of factor VIII are implicated in immunogenic factor VIII uptake, at least in vitro Conversely, in vivo, the binding to endogenous von Willebrand factor masks the reducing effect of mutations in the C domains on factor VIII immunogenicity.
