The hypothesis that immunity and inflammation participate in the pathogenesis of vascular diseases has now gained widespread recognition and stimulated work around the globe. Broadening knowledge has extended the recognition of the role of immune and inflammatory mechanisms to all of the layers of the artery, to all levels of the arterial tree, and implicated virtually all arms, cellular players, and effector molecules and pathways involved in these crucial host defenses, that turn against us in disease. We provide here a guide to a compendium series of articles that aimed to look forward and broaden the traditional focus of immunopathogenesis of arterial disease, with the goal of integrating the players and the layers involved. Although the field has advanced remarkably, much remains to be done, and this commentary also aims to highlight some of the gaps that future research should strive to close on the participation of inflammation and immunity in arterial diseases.
