Summary. Monocytes are the primary inflammatory cell type that infiltrates early atherosclerotic plaques. Their recruitment into plaques drives disease progression. Disease interventions that target monocytes could act at several points: alteration in the phenotype of circulating monocyte subpopulations; reduced recruitment of monocytes into plaques; alterations in the survival of monocyte-derived cells in atherosclerosis; and promotion of migratory egress from plaques to bring about resolution of the plaque inflammatory response. All of these points of intervention will be briefly discussed in this article.
