茶树油 (TTO) 通过减少氧化应激和炎症,减轻中硫化 (H2S) 引起的肺损伤. 这项研究证明了TTO.

科学领域:

兽医科学兽医科学兽医科学
毒理学毒理学毒理学
禽类的健康禽类的健康

背景情况:

来自养殖的硫化 (H2S) 会导致呼吸道炎症和氧化损伤.
茶树油 (TTO) 具有已知的抗氧化和抗炎性质.
之前没有任何研究探讨了H2S诱导的小肺损伤的TTO.

研究的目的:

调查TTO在减轻H2S诱导的的肺损伤中的有效性.
阐明TTO保护作用的基础分子机制.

主要方法:

一个实验模型使用240只一天大的产卵母暴露于H2S,有或没有TTO处理.
使用血素和欧 (H&E) 染色的组织病理学分析.
转录组分析,抗氧化酶测定和qRT-PCR来评估分子变化.

主要成果:

暴露于H2S显著上调了CYP450s (CYP1B1,CYP1C1) 并诱导了氧化应激,亡和炎症.
通过CYP450s/ROS通路,TTO治疗减少了活性氧物种 (ROS) 的产生,并增强了抗氧化能力 (SOD,CAT,T-AOC,GSH-PX).
TTO显著降低了亡因子 (Caspase-8,Caspase-3,Bid,Fas) 和炎症因子 (IL-4,IL-16,NF-κB,TNF-α,IFN-γ) 的表达.

结论:

在中,TTO有效地减轻了H2S诱导的肺损伤.
保护机制包括调节CYP450s/ROS通路,减少氧化应激,亡和炎症.
这些发现为TTO在治疗暴露于H2S的动物中的应用提供了理论支持.

Radical Autoxidation

Radical Autoxidation

The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...

Peroxisomes

Peroxisomes

Peroxisomes are specialized organelles present in fungi, plant, and animal cells. It can vary in number, size, morphology, and activity depending on the type of tissue and the nutritional state of the cell. For example, cells with active lipid metabolism, such as adipocytes, neurons, and hepatocytes, have more peroxisomes than other cells in the body. Besides their primary role in breaking down complex organic molecules, peroxisomes can also synthesize specific macromolecules and participate in...
