Furthermore, 5-aminolevulinic acid-mediated sonodynamic therapy improves cholesterol efflux via activating PPARγ–LXRα–ABCA1/ABCG1 signaling pathways, enhancing efferocytosis and cholesterol efflux, and eventually ameliorating atherosclerosis (79). The gene discussed is ABCG1; the disease is atherosclerosis.
