AGT and aortic aneurysm: To determine the roles of innate immunity in VSMC and aortic pathologies, we performed transcriptome analyses on aortas from ApoE–/– angiotensin II (Ang II)-induced aortic aneurysm (AAA) time course, and ApoE–/– atherosclerosis time course, as well as VSMCs stimulated with danger-associated molecular patterns (DAMPs).
