靶點詳情

  • 最新研究進(jìn)展：
    PF4，全稱為血小板因子4（platelet factor 4），是一種由血小板釋放的化學(xué)因子，具有多種生物學(xué)功能，包括抑制血管內(nèi)皮細(xì)胞增殖和抗菌作用。最近的研究還表明，PF4在腫瘤發(fā)生和發(fā)展中也扮演著重要角色。
  • 功能：
    Released during platelet aggregation. Neutralizes the anticoagulant effect of heparin because it binds more strongly to heparin than to the chondroitin-4-sulfate chains of the carrier molecule. Chemotactic for neutrophils and monocytes. Inhibits endothelial cell proliferation.
