    体外実験

    Dupilumab suppressed mRNA expressions of genes related to activation of T cells, DCs, eosinophils, inflammatory pathways, and TH2-inducing chemokines in skin lesions. No significant reduction in IL-17A or IL-22 levels is detected, but large reductions in expression of IL-17–related genes, such as elafin (PI3), IL23p19/IL23A, and S100A8 and trends for suppression (CXCL1 and S100A7) are found with 300 mg of Dupilumab[1].
    Major suppressions of hyperplasia-related genes (eg, K16) and reductions in expression of S100A genes are evident with 300 mg of Dupilumab by using microarrays and qRT-PCR. The changes in other critical epidermal alterations in severe atopic dermatitis (AD) skin are also measured, including significant increases in claudin and lipid product levels with 300 mg of Dupilumab. A trend of dose-dependent increases in expression of differentiation genes (LOR and FLG) is observed after adjusting for suppression of epidermal hyperplasia, as demonstrated by K16 reductions with Dupilumab[1].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
