Activation of p38α in mouse macrophages after oxidised low-density lipoprotein treatmentTreatment of p38 inhibitor SB203580 blocks foam cell formationMK2 knockout mice display resistance to atherosclerosis developmentDownregulation of p38α resulted in increased apoptosis of macrophages but not required for formation of plaque. This evidence concerns the gene MAPK1 and atherosclerosis.
