概括

血氧化脂类,如EETs和PGFs,在毒症相关的急性损伤 (SA-AKI) 的连续置换疗法 (CRRT) 期间发生变化. 这些转变与患者的预后和免疫微环境相关,指导CRRT调整.

科学领域:

利皮多米克 (Lipidomics) 是一种消化剂.
脏替代疗法治疗脏替代疗法
免疫学免疫学免疫学

背景情况:

血氧化脂质在免疫调节中充当生物活性介质.
氧化脂质在败血症相关急性损伤 (SA-AKI) 进展中的作用和持续置换疗法 (CRRT) 的影响仍然不清楚.

研究的目的:

在SA-AKI患者的CRRT期间调查特定氧化脂质的变化.
为了将这些脂质变化与免疫微环境和患者预后相关联.

主要方法:

对接受CRRT的48名SA-AKI患者进行前性队列研究.
在基线 (T0) 和72小时 (T72) 时使用超高性能液体色谱-并联质谱 (UPLC-MS/MS) 分析的血氧化脂组.

主要成果:

非幸存者在T0时显示较低的EET,EpOMEs,EpDPEs和较高的PGF,TXB,HEPEs.
在CRRT后,非幸存者增加了DiHETEs和减少了PGFs,而幸存者增加了HEPEs,EpOMEs,并减少了6keto-PGF1α.
途径分析显示,CRRT后的幸存者的差异性脂质在代谢途径中的丰富和上调.

结论:

这项研究提供了在CRRT期间SA-AKI患者血氧化脂质的全面观点.
通过去除PGFs/TXs和增加HEPE,调节免疫微环境,CRRT可以改善SA-AKI的预后.
血氧化脂类药物可以为个性化CRRT处方调整提供信息.

Lipid-derived Compounds in the Human Body

Lipid-derived Compounds in the Human Body

Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...

Asymmetric Lipid Bilayer

Asymmetric Lipid Bilayer

Biological membranes show uneven distribution of different types of lipids in the inner and outer layers, resulting in transverse asymmetric membranes. The treatment of the erythrocyte membrane with the enzyme phospholipase confirmed the asymmetric nature of the lipid bilayer. The enzyme hydrolyzes lipids into fatty acids and hydrophilic groups. The phospholipase acts only on the outer layer of the membrane, while the inner layer remains intact. The phospholipase treatment resulted in 80%...

Lipids as Anchors

Lipids as Anchors

In the plasma membrane, the lipids forming the bilayer can also act as an anchor to tether proteins to the membrane. The three main types of lipid anchors found in eukaryotes are – prenyl groups, fatty acyl groups, and glycosylphosphatidylinositol or GPI groups. Prenyl and fatty acyl groups act as anchors on the cytosolic surface of the membrane, whereas GPI anchors proteins on the extracellular side.
The carboxy-terminal of most of the prenylated proteins, such as Ras proteins, contains...
