In further exploration of the subsets of DCs (Sun et al. 2020), it was found that CD11b+DC (Stoneman et al. 2007; Busch et al. 2014; Gao et al. 2016; Rombouts et al. 2016) and CCL17+DC (Rader and Daugherty, 2008; Weber et al. 2011) subsets have the effect of promoting atherosclerosis, and further exploration under more experimental conditions will provide multi-dimensional evidence. This evidence concerns the gene CCL17 and atherosclerosis.
