Extracellular-vesicle containing miRNA-503-5p released by macrophages contributes to atherosclerosis


Figure 9. Systematic diagrams illustrating how macrophages crosstalk with ECs and SMCs and how they involve in the formation of atherosclerotic plaques. Macrophages deliver miR-503-5p to HCAECs and HCA-SMCs via EVs and downregulate Smad7, smurf1, and smurf2 in HCAECs and HCASMCs, thereby inhibiting proliferation, migration, and angiogenic abilities of HCAECs, but promoting proliferation and migration of HCASMCs.
