[Abstract]  Lipopolysaccharide is the major constituent of the outer membrane of gram-negative bacteria and, once released from the bacterial surface into the bloodstream, is a potent activator of the host immune system, which can lead to septic shock. LPS has a hydrophilic region consisting of a repeating oligosaccharide that is strain-specific (O-antigen) and a core polysaccharide, which is covalently linked to a hydrophobic lipid moiety (lipid A). Lipid A is the most conserved part and is responsible for the toxicity of LPS. Therefore, finding molecules able to bind to this region and neutralize LPS ... [摘要]  脂多糖是革兰氏阴性细菌外膜的主要成分,一旦从细菌表面释放到血液中,是宿主免疫系统的有效激活剂,可导致败血性休克。 LPS具有由与疏水性脂质部分(脂质A)共价连接的作为菌株特异性(O-抗原)的重复寡糖和核心多糖组成的亲水性区域。脂质A是最保守的部分,负责LPS的毒性。因此,寻找能够结合该区域并中和LPS毒性的分子是有兴趣的,因为它可能提供新的治疗方法来预防败血性休克(Chen et al。,2006)。报道了几种蛋白质和肽结合LPS并改变其对还原和甚至增强的毒性(Brandenburg等,1998),例如血清白蛋白(Ohno和Morrison,1989),脂多糖结合蛋白(LBP)(de Haas等人,1999),酪蛋白(López-Expósito等,2008),溶菌酶,抗生素多粘菌素B和抗菌肽(Chen等,2006)。虽然这些蛋白质中的一些是中性的,甚至阴离子/酸性(pI <7)(jang et="" al。,2009),由于lps的两亲性结构和脂质a上带负电荷的磷酸酯基团的存在是最重要的因素被认为与lps最佳结合的是阳离子/碱性(pi=""> ...
