In line with our current results regarding the preservation of vascular elastin by the photochemical treatment, our prior investigations utilizing the mouse elastase model of aortic abdominal aneurysms revealed a delayed onset of aneurysm development and the maintenance of smooth muscle cell content in aortas that had previously undergone treatment with 10-8-10 Dimer and blue light [30]. Here, ELN is linked to abdominal aortic aneurysm.
