Atherosclerosis is a leading death cause. Endothelial and smooth muscle cells
participate in atherogenesis, but it is unclear whether other mesenchymal cells
contribute to this process. Bone marrow (BM) nestin(+) cells cooperate with
endothelial cells in directing monocyte egress to bloodstream in response to
infections. However, it remains unknown whether nestin(+) cells regulate
inflammatory cells in chronic inflammatory diseases, such as atherosclerosis.
Here, we show that nestin(+) cells direct inflammatory cell migration during
chronic inflammation. In Apolipoprotein E (ApoE) knockout mice fed with high-fat
diet, BM nestin(+) cells regulate the egress of inflammatory monocytes and
neutrophils. In the aorta, nestin(+) stromal cells increase ?30 times and
contribute to the atheroma plaque. Mcp1 deletion in nestin(+) cells-but not in
endothelial cells only- increases circulating inflammatory cells, but decreases
their aortic infiltration, delaying atheroma plaque formation and aortic valve
calcification. Therefore, nestin expression marks cells that regulate
inflammatory cell migration during atherosclerosis.
