摘要

氧化脂素是一种重要的信号化合物，在免疫系统的调节和炎症的消退中起着重要的作用。脂质代谢在SARS-CoV-2感染时被强烈激活，但不同变体诱导的氧化脂素的调节作用仍未被探索。在这里，我们比较了感染野生型、α (B.1.1.7)、Delta (B.1.617.2)和Omicron (B.1.1.529)变体的受试者的37种氧脂素和4种PUFAs的血浆谱。结果表明，COVID-19引起的氧化应激和炎症高度依赖于SARS-CoV-2变异，其中野生型引发的炎症风暴最强。α和δ变异在感染后引起类似的脂质谱改变，这与Omicron有显著不同。在感染患者中，后一种变异增加了促炎介质的水平，降低了omega-3 PUFA的水平。我们推测，除了病毒突变外，治疗方法、疫苗接种和先前感染的变化也可能对氧脂质谱的改变起作用。这些结果为COVID-19炎症反应的演变提供了新的思路。

The effect of SARS-CoV-2 variants on the plasma oxylipins and PUFAs of COVID-19 patients

Oxylipins are important signalling compounds that are significantly involved in the regulation of the immune system and the resolution of inflammation. Lipid metabolism is strongly activated upon SARS-CoV-2 infection, however the modulating effects of oxylipins induced by different variants remain unexplored.

Here, we compare the plasma profiles of thirty-seven oxylipins and four PUFAs in subjects infected with Wild-type, Alpha (B.1.1.7), Delta (B.1.617.2), and Omicron (B.1.1.529) variants.

The results suggest that oxidative stress and inflammation resulting from COVID-19 were highly dependent on the SARS-CoV-2 variant, and that the Wild-type elicited the strongest inflammatory storm. The Alpha and Delta variants induced a comparable lipid profile alteration upon infection, which differed significantly from Omicron. The latter variant increased the levels of pro-inflammatory mediators and decreased the levels of omega-3 PUFA in infected patients.

We speculate that changes in therapeutics, vaccination, and prior infections may have a role in the alteration of the oxylipin profile besides viral mutations. The results shed new light on the evolution of the inflammatory response in COVID-19.
