一般描述
本品是从马流产沙门氏菌中提取的苯酚。源菌株是ATCC 9842。来自马流产沙门氏菌的脂多糖刺激人单核细胞产生肿瘤坏死因子。这种LPS对青蛙和小鼠淋巴细胞也具有促有丝分裂作用。
应用
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部分可通过Toll样受体4（TLR4）刺激先天免疫系统细胞，TLR4是Toll样受体蛋白家族的成员，它能识别常见的病原体相关分子模式（PAMP）。
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。
制备说明
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。

Systemic inflammatory events often precipitate acute cognitive dysfunction in elderly and demented populations. Delirium is a highly prevalent neuropsychiatric syndrome that is characterized by acute inattention and cognitive dysfunction, for which prior dementia is the major predisposing factor and systemic

Subtle regional differences in microglial phenotype exist in the adult mouse brain. We investigated whether these differences were amplified during ageing and following systemic challenge with lipopolysaccharide (LPS). We studied microglial morphology and phenotype in young (4mo) and aged (21mo)
