Linking CD11b (+) Dendritic Cells and Natural Killer T Cells to Plaque Inflammation in Atherosclerosis.

ABSTRACT: Atherosclerosis remains the leading cause of death and disability in our Western society. To investigate whether the dynamics of leukocyte (sub)populations could be predictive for plaque inflammation during atherosclerosis, we analyzed innate and adaptive immune cell distributions in blood, plaques, and lymphoid tissue reservoirs in apolipoprotein E-deficient (ApoE(-/-)) mice and in blood and plaques from patients undergoing endarterectomy. Firstly, there was predominance of the CD11b(+) conventional dendritic cell (cDC) subset in the plaque. Secondly, a strong inverse correlation was observed between CD11b(+) cDC or natural killer T (NKT) cells in blood and markers of inflammation in the plaque (including CD3, T-bet, CCR5, and CCR7). This indicates that circulating CD11b(+) cDC and NKT ce
