一般說明
本品是从肠炎沙门氏菌中提取,经凝胶过滤纯化而得。源菌株是ATCC 13076。肠炎沙门氏菌的脂多糖在鼠脾细胞中具有致突变性,并在这些细胞中引起噬菌斑形成反应。
應用
脂多糖 (LPS) 是革兰氏阴性菌细胞壁的特征性成分。LPS 及其脂质 A 部分通过 Toll 样受体 4 (TLR4) 刺激天然免疫系统的细胞。
生化/生理作用
脂多糖(LPS)位于膜的外层,并且暴露在无包膜菌株的细胞表面。它们有助于维持外层膜的完整性,并保护细胞免受胆汁盐和亲脂性抗生素的破坏。
準備報告
本品溶于水(5 mg/ml)或细胞培养基(1 mg/ml),得到浑浊的淡黄色溶液。以盐水为溶剂时,经过涡旋并加热至70-80 oC后,得到浓度更高但仍然浑浊的溶液(20 mg/ml)。脂多糖分子可在各种溶剂中形成胶束。在水和磷酸盐缓冲盐水中,可观察到混浊的溶液。使用有机溶剂不会得到更澄清的溶液。以甲醇为溶剂将得到含漂浮物的混浊悬浮液,而以水为溶剂将得到均匀的混浊溶液。

Acute lung injury (ALI) remains a major challenge in critical care medicine. Both neutrophils and chemokines have been proposed as key components in the development of ALI. The main chemokine receptor on neutrophils is CXCR2, which regulates neutrophil recruitment and

Peroxisome proliferator activated receptor-gamma (PPARgamma) has been reported to exert anti-inflammatory properties in endotoxic shock and sepsis. One phenomenon that alters the inflammatory response to endotoxin [lipopolysaccharide (LPS)] is endotoxin tolerance, which is caused by previous exposure to endotoxin. Here

The Duffy antigen receptor for chemokines (DARC) has a high affinity for CC and CXC chemokines. However, it lacks the ability to induce cell responses that are typical for classical chemokine receptors. The role of DARC in inflammatory conditions remains

Bacterial and fungal infections and the emerging multidrug resistance are driving interest in fighting these microorganisms with natural products, which have generally been considered complementary to pharmacological therapies. Phlorotannins are polyphenols restricted to brown seaweeds, recognized for their biological capacity.
