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。
通过苯酚-氯仿-石油醚萃取进行制备。

Hypoxia-inducible factor-1α (HIF-1α) and toll-like receptor 4 (TLR4) are involved in numerous mechanisms of cancer biology, including cell proliferation and survival; however the interaction of the two factors under hypoxic conditions remains unclear. The present study investigated the in vitro

The ability to activate macrophages in vitro for nitric oxide production and killing of Leishmania major parasites is dependent on tumor necrosis factor, although L. major-infected mice lacking the TNF receptor p55 (TNFRp55(-/-) mice) or both the TNFRp55 and TNFRp75

A monoclonal antibody to the lipopolysaccharide of Moraxella bovis is described. In an indirect fluorescent-antibody test, this monoclonal antibody reacted with 39 of 39 strains of M. bovis tested and did not react with 26 nonfermenting gram-negative coccobacilli other than

Emerging evidence suggests that TLR (Toll-like receptor) 4 and downstream pathways [MAPKs (mitogen-activated protein kinases) and NF-κB (nuclear factor κB)] play an important role in the pathogenesis of insulin resistance. LPS (lipopolysaccharide) and saturated NEFA (non-esterified fatty acids) activate TLR4
