A total of 20,464 single CD45+ immune cells were identified with the following distribution per condition: 1670 immune cells in five healthy-looking skin samples (i.e., with 895 myeloid cells and 775 LCs), 1703 in two patients with Kawasaki syndrome (i.e., with 932 myeloid cells and 775 LCs), 5076 in three patients with SLE chilblain (i.e., with 1560 myeloid cells and 3516 LCs), and 12,015 in five patients with COVID-toes (i.e., with 2838 myeloid cells and 9177 LCs). Here, PTPRC is linked to systemic lupus erythematosus.
