GLs and sphingolipids that significantly affected upon polarisation. a PC (14:2/16:0), b PS (18:0/20:4), and c PE (18:1/22:6) represent some GLs increased significantly in M1 or M2 macrophages compared to M0 macrophages. d Ceramide (d18:1/24:0), e Ceramide (d18:1/22:0) and f Ceramide (d18:1/16:0) as potential key characteristic metabolites of M1 macrophages and their significant increase compared to M0 and M2 macrophages
