Yet, the recently available single cell sequencing data describing the immune landscape of lupus nephritis revealed five clusters of myeloid cells [114], whereby cells in cluster 4 (CM4) were found to express the index markers of ercDCs, CD14, CD209 and CD163, together with further ercDC marker genes CD64, VSIG4, MSR1, STAB1, MerTK, FOLR2 and C1Q. Here, CD209 is linked to lupus nephritis.
