一般描述

该产品是从大肠埃希菌血清型O128:B12中提取，并经凝胶过滤纯化。源菌株为CDC 2440-69。

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。

Anti-inflammation action of xanthones from Swertia chirayita by regulating COX-2/NF-κB/MAPKs/Akt signaling pathways in RAW 264.7 macrophage cells.

Tian-Yong Hu et al.

Phytomedicine : international journal of phytotherapy and phytopharmacology, 55, 214-221 (2019-01-23)

Swertia chirayita, has been commonly used under the name "Zang-yin-chen" for the treatment of liver infections, inflammation, abdominal pain, and bacterial infection in traditional Tibetan medicine. However, the bioactive components with anti-inflammatory activities and underlying mechanisms remain poorly evaluated. Repeated

Tafazzin deficiency in mouse mesenchymal stem cells potentiates their immunosuppression and impairs activated B lymphocyte immune function.

Journal of inflammation research, 14, 587-597 (2021-03-06)

Marine natural products harbor a variety of pharmacological activities, and the sea species have been becoming a main source of new drug candidate. In pursuit of safer and more effective anti-inflammation drug, the anti-inflammatory activities, anti-oxygenation effects and underlying molecular

Macrophage autophagy protects against liver fibrosis in mice.

Jasper Lodder et al.

Autophagy, 11(8), 1280-1292 (2015-06-11)

Autophagy is a lysosomal degradation pathway of cellular components that displays antiinflammatory properties in macrophages. Macrophages are critically involved in chronic liver injury by releasing mediators that promote hepatocyte apoptosis, contribute to inflammatory cell recruitment and activation of hepatic fibrogenic
