Lipopolysaccharides試劑生物活性

ipopolysaccharides (LPS)是一種內(nèi)毒素來源于外層膜的外膜革蘭氏陰性細(xì)菌。脂多糖由抗原O-specific鏈,一個核心的低聚糖和脂質(zhì)a脂多糖是一種病原相關(guān)分子模式(PAMP時),激活免疫系統(tǒng)。脂多糖對免疫細(xì)胞激活地[1][2][3]。這個產(chǎn)品來源于大腸桿菌O55: B5。脂多糖誘導(dǎo)的分泌細(xì)胞migrasome

TLR4

體外研究
(In Vitro)

Lipopolysaccharides (10–80 μg/mL) selectively decreases THir (tyrosine hydroxylase immunoreactive) cells and increases culture media levels of interleukin1β (IL-1β) and tumor necrosis factor-α (TNF-α) as well as nitrite (an index of nitric oxide (NO) production)^[5].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

體內(nèi)研究
(In Vivo)

Lipopolysaccharides (1.5 mg/kg; i.p.; once) induces sickness and hypothermia in mice, and induces a greater and more prolonged sickness response in adult male mice^[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Female and male CD1 mice^[3]
Dosage:	1.5mg/kg
Administration:	Intraperitoneal injection, once
Result:	Induced sickness behavior in all mice, but adult mice displayed more sickness than pubertal mice and adult males remained sick for a longer period of time than adult females. Caused a decrease in body temperature for all mice, but this decrease was greatest in adult males. Increased pro- and anti-inflammatory cytokines at various levels in pubertal and adult male and female mice, resulted in age and sex differences in cytokine concentrations following immune challenge. Only adult males and females treated with LPS displayed significantly more IL-6 than their saline controls, and pubertal males and females and adult females displayed significantly more IL-10 than their saline controls. All the mice displayed significantly more IL-12 and TNF-α than their saline controls.
