Metabolic syndrome (MetS) is a complex condition encompassing a constellation of cardiometabolic abnormalities. Oxylipins are a superfamily of lipid mediators regulating many cardiometabolic functions. Plasma oxylipin signature could provide a new clinical tool to enhance the phenotyping of MetS pathophysiology.

This study extends the concept to the phospholipids (PLs) category and shows that the APCI source can also be used. Moreover, the coupling with NP-LC allows to simultaneously analyze different PLs classes in the same sample.

This can be achieved by putting them in the context of genome-scale metabolic network reconstructions. However, mapping experimentally measured molecules onto metabolic networks is challenging due to differences in identifiers and level of annotation between data and metabolic networks, especially for lipids.

In order to survive, has developed several strategies to manipulate macrophage functions. Among these strategies, as a source of bioactive lipids has been poorly explored.
