circMETTL3 expression is increased in CD11b-labeled mononuclear macrophages from sHLH patients compared with healthy controls, supported by fluorescence colocalization. The study further links circMETTL3 to macrophage glycolysis and M1 polarization.
CircMETTL3-156aa reshapes the glycolytic metabolism of macrophages to promote M1 polarization and induce cytokine storms in sHLH.
