Serum sphingolipid profile in asthma
Chenglin Guo, Lina Sun, Linlin Zhang, Fawu Dong, Xu Zhang, Liu Yao, Chun Chang

Pages: 53-59 | First Published: 18 February 2021


Graphical Abstract

Liquid chromatography-mass spectrometry-based targeted metabolomic profiling was performed on serum samples from both patients with asthma and control subjects. Sphingomyelin (SM) levels were significantly decreased in the asthma patients compared to the healthy controls. SM levels were also decreased in the blood noneosinophilic asthma group compared with the blood eosinophilic asthma group and in the early-onset group compared with the late-onset group. SM may be involved in the pathogenesis of asthma and related to different inflammatory cell subtypes. SM is thought to be a protective factor in asthma.
