ABSTRACT
During the past decade it has become increasingly clear that platelets exert important
functions in the context of inflammation, beyond their role in hemostasis. Platelets
may adhere to intact endothelial cells and promote local vascular inflammation by
recruiting leukocytes via direct interactions or by secreting inflammatory mediators
such as chemokines. Accordingly, platelet-derived chemokines play a crucial role in
directing leukocytes to sites of vascular injury or dysfunction, thereby contributing
to neointimal hyperplasia or atherosclerosis. In this review, we discuss the function
of platelets as immune cells that potentiate vascular inflammation with a special
focus on platelet-derived chemokines: their effects and interactions and their potential
quality as targets for the treatment and/or prevention of cardiovascular disease.
