(B) Msr1+/+ (WT) and Msr1-/- (KO) M0 macrophages and M2(IL-4) macrophages untreated or stimulated with the MSR1 ligands fucoidan or oxLDL (50 μg/ml, 30 min) were analysed for the phosphorylated and the total forms of JNK1/2 and MSR1. ITGAM (CD11b) serves as a loading control. Both fucoidan and oxLDL activate JNK in a MSR1-dependent manner.
