MoMacs in lupus nephritis biopsies showed increased expression of CCR5 and FRP3 in lupus nephritis (Supplemental Figure 4D), mirroring our findings in MRL-Lpr kidneys, and there was also increased expression of SEMA4D in both MoMac and TrMac subsets (Supplemental Figure 4D). This evidence concerns the gene CCR5 and lupus nephritis.
