Photobiomodulation therapy (PBMT) could protect against atherosclerosis. A, Schematic diagram. Apolipoprotein E (ApoE)^−/− mice fed with a western diet (WD) for 18 wk and treated with PBMT in the last 10 wk. B, Representative ORO staining and quantitative analysis of atherosclerosis lesion area in ApoE ^−/− mice aortas (n = 7). C‐F, Representative ORO, H&E and Masson's trichrome staining and quantitative analysis of the lesion area D, necrotic core E, and collagen content F, in the aortic sinus. Scale bars, 400 μm (n = 8). Data are shown as mean ± SEM, WD vs. WD + PBMT, unpaired two‐tailed Student's t test. *P < .05, **P < .01, ns = not significant
