脂多糖（Lipopolysaccharide, LPS）是革兰氏阴性细菌外膜的主要成分之一，由类脂A、核心多糖和O-抗原三部分组成，其中O-抗原决定了LPS的血清型，具有重要的生物学功能和作用机制。

2014年3月22日 · Sunil's Sick Day is the twenty-second episode of the second season of Littlest Pet Shop and the forty-eighth episode overall. When Sunil and Vinnie have a falling out, it is up to Blythe and Russell to figure out how to get these two best pals back together again.

心脏功能障碍 (心脏炎症) 是脂多糖 (lps) 诱导脓毒症的常见并发症，其原因是严重的炎症反应。lps 还可引起心脏收缩功能恶化，心脏脂质过氧化增加，导致心脏功能障碍。

Being sick is the worst, right? Well here are my top ten reasons I hate being sick! What do you dislike about being sick? Comment below! Wanna connect? ↓♡ In...

Russell: So even if Sunil weren't sick, you wouldn't speak to him if he was here because you're mad at him for yelling at you! Vinnie: Listen, Cyril, Sunil's not sick and I'm not mad at him for yelling at me; I'm mad at him for something else. And if you get me another slice of yummy mango, I'll tell you why.

脂多糖是一种常见的内毒素 (Endotoxin)，在体内可以通过细胞信号转导系统激活单核巨噬细胞、内皮细胞、上皮细胞等，合成和释放多种细胞因子和炎性介质，进而引起机体一系列的反应。 其主要作用机理已研究的较为透彻，如图2所示，当LPS进入机体入血后，脂多糖结合蛋白LBP可以识别LPS，与LPS单体结合运送至 髓源性细胞 表面。 髓源性细胞表面的mCD14与之结合，形成LPS-LBP-CD14三联复合体，随后将其转运至TLR4-MD2蛋白复合体处，三联复合体在MD-2的帮助 …

2017年9月23日 · Lily is sick! And her sister fills in for her, but some things do and don't go to plan...Watch to find out more!

Lipopolysaccharide (LPS), a component of gram-negative bacteria, is widely used to systematically stimulate the immune system and generate profound physiological and behavioural changes, also known as 'sickness behaviour' (e.g. anhedonia, lethargy, loss of …

脂多糖（Lipopolysaccharide, LPS）是革兰氏阴性细菌外膜的重要成分，对细菌的生存和致病性具有重要影响。 LPS位于细菌外膜的外层，在无荚膜菌株中直接暴露在细胞表面。
