FOXP3 and atherosclerosis: Our recent work revealed that broad-band UVB (a continuous spectrum from 280 to 320 nm with a peak around 313 nm) exposure attenuates the development and progression of atherosclerosis in Apoe−/− mice, associated with a systemic increase in CD4+Foxp3+ Tregs with higher suppressive capacity and a decrease in proinflammatory IFN-γ production from T cells [122].
