    体外研究
    (In Vitro)

    Cecropin B-induces NF-κB activation playing a pivotal role in the suppression of CYP3A29 through disrupting the association of the PXR/retinoid X receptor alpha (RXR-α) complex with DNA sequences. Cecropin B activates pig liver cells by interacting with TLRs 2 and 4, which modulated NF-κB-mediated signaling pathways[1].

    (In Vivo)

    The wounds are moist with more exudation in C group, while that in other groups are dry without obvious exudation. The body temperature of the majority of the mice in each group is elevated, but the number of leucocytes in each group is lowered after operation. The quantity of bacteria in muscle in A group is obviously lower than that in M group and C group. The number of surviving mice after 4 PID in C group is evidently smaller than that in A and M groups( P<0. 05)[2].

    Mice[1]
    Thirty ICR mice are enrolled in the study, and the Pseudomonas aeruginosa infection model is reproduced by excision of the full layer of dorsal skin with an area of 1 cm x 1 cm. Then they are randomly divided into C (control, n=10, with wet compress of isotonic saline at 3 postinjury hour (PIH)) , M (with hydropathic compress of 100 g/L mafenide at 3 PIH), A (with wet compress of 1 000 mg/L Cecropin B at 3 PIH) groups. The changes in body temperature and hemogram in each group are determined before and 4 days after injury[2].

    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.
