Atherogenesis is accompanied by formation of immune cell aggregates, so-called artery tertiary lymphoid organs (ATLOs), in the outermost layer of diseased arteries. In a recent study, Mohanta, Habenicht, and colleagues revealed that there are distinct interactions between ATLOs and the autonomous nervous system, which are critically implicated in atherosclerosis progression.
