一般說明

该产物是从大肠杆菌血清型O127:B8中苯酚提取得到。源菌株为ATCC 12740。该LPS血清型已经用于脓毒性休克的研究,并且可在大鼠肾小球masangial细胞中诱导小鼠巨噬细胞和PAF中的NOS合成。

應用

脂多糖(LPS)是革兰氏阴性菌细胞壁的特征组分。LPS及其脂质A部分可通过能够识别常见的病原体相关分子模式(PAMP)的Toll样受体蛋白家族成员Toll样受体4(TLR4)刺激先天性免疫系统细胞。

生化/生理作用

脂多糖(LPS)位于膜的外层,并且在非包封的菌株中暴露在细胞表面上。它们有助于外膜的完整性,并保护细胞免受胆汁盐和亲脂性抗生素的作用。

準備報告

该产品可溶于水(5mg/mL)或细胞培养基(1mg/mL),并产生浑浊的淡黄色溶液。在涡旋并升温至70-80 oC后,在盐水中可获得更加浓缩但仍然浑浊的溶液(20mg/ml)。脂多糖是一种能在各种溶剂中形成胶束的分子。在水和磷酸盐缓冲盐水中可观察到浑浊的溶液。通过有机溶剂无法获得更澄清的溶液。在甲醇会产生含有漂浮物的混浊悬浮液,而在水中则产生均匀的浑浊溶液。

Our previous study has reported that the proactive secretion and role of central high mobility group box 1 (HMGB1) in lipopolysaccharide-induced depressive behavior. Here, the potential mechanism of HMGB1 mediating chronic-stress-induced depression through the kynurenine pathway (KP) was further explored

Acute lung injury (ALI) is a common clinical disorder that causes substantial health problems worldwide. An excessive inflammatory response is the central feature of ALI, but the mechanism is still unclear, especially the role of endoplasmic-reticulum (ER) stress and autophagy.

Obesity-induced inflammation engenders insulin resistance and type 2 diabetes mellitus (T2DM) but the inflammatory effectors linking obesity to insulin resistance are incompletely understood. Here, we show that hepatic expression of Protein Tyrosine Phosphatase Receptor Gamma (PTPR-γ) is stimulated by inflammation

In humans, depression is often associated with low-grade inflammation, activation of the tryptophan/kynurenine pathway, and mild lymphopenia. Preclinical research confirms that inflammation induces depression-like behavior through activation of the tryptophan/kynurenine pathway. However, the mechanisms governing recovery from depression are unknown.

Co-chaperone cytoplasmic constitutive active/androstane receptor retention protein (CCRP), a member of heat shock protein (HSP) 40, was first characterized to retain a nuclear-destined protein in the cytoplasm. Here we have used CCRP KO mice and demonstrated that CCRP suppresses lipopolysaccharide
