Podosomes are dynamic adhesion structures found in dendritic cells (DCs) and other cells of the myeloid lineage. We previously showed that prostaglandin E2 (PGE2), an important proinflammatory mediator produced during DC maturation, induces podosome disassembly within minutes after stimulation. Here, we demonstrate that this response is mediated by cAMP(More)
OBJECTIVE The role of Chlamydia pneumoniae in atherosclerosis is still debated. In this study a novel mouse model was applied to determine the direct impact of C. pneumoniae on the arterial wall and the development of atherosclerosis. METHODS Direct effects of C. pneumoniae on collar-induced atherosclerosis were studied after local delivery of C.(More)
P-selectin is of critical importance in early atherogenesis by initiating leukocyte rolling at the site of endothelial injury. In order to validate P-selectin as a candidate target for the development of anti-atherogenic strategies, we wanted to obtain quantitative information on P-selectin expression, and identify novel peptide-based lead structures that(More)
BACKGROUND Interleukin 15 (IL-15) is a pro-inflammatory cytokine involved in inflammatory diseases and IL-15 is expressed in atherosclerotic plaques. METHODS To establish the role of IL-15 in atherosclerosis we studied the effect of IL-15 on atherosclerosis associated cells in vitro and in vivo by neutralizing IL-15 using a DNA vaccination strategy.

OBJECTIVE Vascular endothelial growth factor receptor 2 (VEGFR2)-overexpressing cells may form an interesting target for the treatment of atherosclerosis because of their involvement in processes that contribute to this disease, such as angiogenesis. METHODS AND RESULTS We vaccinated mice against VEGFR2 by an orally administered DNA vaccine, comprising a(More)
