General description

脂质A是脂多糖(LPS)的基本结构,存在于细菌中。

Application

使用脂质A,来自大肠杆菌F583(Rd突变)的焦磷酰:
  • 研究不同脂类A分子对体外肺周细胞增殖的影响
  • 在THP-1和J774A.1细胞,分别形成新蝶呤和亚硝酸盐
  • 在结合实验中用作脂多糖(LPS)衍生物
  • 刺激脾脏细胞并为toll样受体4 (TLR4)的有丝分裂原刺激

Biochem/physiol Actions

脂质A是人体内脂多糖(LPS)强大的免疫刺激活性活动所必需的物质。脂质A是脂多糖的疏水结构域,有助于将脂多糖锚定在细菌的质膜上。它具有免疫活性,是可由免疫系统识别的脂多糖的重要组成部分。
