Demyelination and inflammation are two main features of multiple sclerosis. It has been proved that lipids play an important role in these two processes and to elucidate their mechanism of action in MS, a lipidomics approach was applied to iPSC-derived human 3D brain spheres system challenged by a treatment with cytokines to induce the demyelination. Combining targeted and untargeted lipidomics, we detected different classes of lipids in both spheres and their corresponding media. Among the measured lipid species, PAF and PAF related species were found to be significantly upregulated in the cytokine-treated spheres while the PUFA species and derived eicosanoids were increased in the spent media, suggesting a link between the early stage of inflammation process in MS and activated lipid signaling.
