Cluster 5 showed a gene expression profile that was characterized by the expression of Btla, Ccr7, Tbc1d4, Ccl22, and Ly6d (Figure 2G and Figure S3) revealing a population of MoDC/DC cells (Figure 2F,G) present in the aortas that were independent of the atherosclerosis predisposition or the diet (Figure S2D). Here, LY6D is linked to atherosclerosis.
