一般描述

本品从大肠杆菌血清型K235中提取，经凝胶过滤纯化。来源菌株为 ATCC 13027。

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。

制备说明

产物可溶于水（5mg/ml）或细胞培养基（1mg/ml），产生浑浊的淡黄色溶液。在经过涡旋，并升温至 70-80^oC 后，含水盐水变得更浓缩，但仍然浑浊（20mg/ml）。脂多糖分子在每种溶剂中均形成胶束。在水和磷酸盐缓冲盐水中观察到浑浊的溶液。使用有机溶剂，溶液也是浑浊的。甲醇产生具有漂浮物的浑浊悬浮液，而水则产生均匀浑浊的溶液。

Bacterial lipopolysaccharide induces the intracellular expression of trophoblastic specific CD74 isoform in human first trimester trophoblast cells: Correlation with unsuccessful early pregnancy.

Waleed Al Abdulmonem et al.

Journal of reproductive immunology, 141, 103152-103152 (2020-06-11)

During first trimester of human pregnancy, the maternal system develops immunity against infection and to provide protection of allogeneic foetus from abortion. This study was undertaken to determine the role of trophoblast specific CD74 isoforms in first trimester trophoblast derived

Early life stress from allergic dermatitis causes depressive-like behaviors in adolescent male mice through neuroinflammatory priming.

Okito Hashimoto et al.

Brain, behavior, and immunity, 90, 319-331 (2020-09-21)

Allergic dermatitis (AD), associated with pruritus and itchiness, is one of the major stressful conditions early in life. AD also influences the incidence of neuropsychiatric disorders and developmental disorders through neuro-immune interactions. To the best of our knowledge, there is

Gene expression patterns in experimental colitis in IL-10-deficient mice.

Jonathan J Hansen et al.

Inflammatory bowel diseases, 15(6), 890-899 (2009-01-13)

While others have described gene expression patterns in humans with inflammatory bowel diseases and animals with chemically induced colitis, a genome-wide comparison of gene expression in genetically susceptible animals that develop spontaneous colitis has not been reported. We used microarray

Structure and mechanism of bactericidal mammalian perforin-2, an ancient agent of innate immunity.

Tao Ni et al.

Science advances, 6(5), eaax8286-eaax8286 (2020-02-18)

Perforin-2 (MPEG1) is thought to enable the killing of invading microbes engulfed by macrophages and other phagocytes, forming pores in their membranes. Loss of perforin-2 renders individual phagocytes and whole organisms significantly more susceptible to bacterial pathogens. Here, we reveal
