Cluster #1 expressed KLF4 as previously described in cDC2B, but not RORC31, and CD14 and SOD2 as previously described DC344, but not C5AR1 nor CD163. Cluster #8 overexpressed the T-cell-attracting chemokine CXCL10, whereas mmDC #4 overexpressed CXCL9. Cluster #7 expressed CD209 (DC-SIGN) but not CCR7 and was preferentially from the AD skin samples. Here, KLF4 is linked to Alzheimer disease.
