Consistent with our findings, a study reveals that CM highly express S100A8, S100A9, and S100A12, IM express HLA-DQA1 and HLA-DPA1 and NCM mainly express CD16, demonstrating a distinct transcriptome across monocyte subsets in Kawasaki disease (Geng et al., 2021). Here, HLA-DPA1 is linked to Kawasaki disease.
