To trace CD2+MHC-II+CCR2+ myeloid precursors to the skin, we integrated the human synovial myeloid cell clusters into an existing scRNA-seq dataset of skin myeloid cells (E-MTAB-8142)29 containing samples from healthy donors (N = 5), individuals with psoriasis (N = 3) and individuals with atopic dermatitis (AD; N = 4). This evidence concerns the gene CCR2 and psoriasis.
