自从Neter在20世纪50年代末发现细菌内毒素脂多糖(LPS)很容易与哺乳动物细胞结合以来,内毒素研究人员对LPS特异性受体的概念产生了浓厚的兴趣。为了在实验上证明这种LPS受体的存在,已经采用了多种免疫学、生化和形态学方法;然而,总的来说,这些努力被相对高水平的与哺乳动物细胞膜成分的非特异性结合所混淆(见16)。b施普林格和他的同事在1970年发现了一种存在于人红细胞上的特异性膜定位高亲和力脂多糖结合脂蛋白(24,25),尽管将这些观察结果扩展到人血小板、白细胞或小鼠淋巴细胞的努力不太成功(26,27)。最近,几位研究人员的努力提供了强有力的证据,证明LPS的特定制剂中的碳水化合物成分存在于不同的细胞亚群中,但迄今为止,LPS的结构保守、生物活性的脂质A成分的特异性受体尚未确定。
Since the discovery by Neter in the late 1950’s that bacterial endotoxic lipopolysaccharides (LPS) will bind readily to cells of mammalian origin (reviewed in 15), the concept of specific receptors for LPS has intrigued endotoxin researchers. A variety of immunologic, biochemical and morphologic approaches have been adopted in order to demonstrate experimentally the existence of such LPS receptors; in general however, such efforts have been confounded by relatively high levels of nonspecific binding to mammmalian cell membrane components (reviewed in 16). A specific membrane localized high affinity LPS binding lipoglycoprotein present on human erythrocytes was identified by Springer and his colleagues in 1970 (24, 25), although efforts to extend these observations to human platelets and leukocytes or murine lymphocytes were less successful (26, 27). More recent efforts by several investigators have provided strong evidence for receptors on distinct cell subpopulations for carbohydrate components of specific preparations of LPS, (reviewed in 7), but the specific receptor for the structurally conserved, biologically active lipid A component of LPS has, to date, not been defined.
