The top cell-specific genes with respect to FC were LAMP3 in the CD4+ T cells (FC in SLE 11.0 and FC in immunised ND 9.0), CCL2 in the CD16− monocytes (FC in SLE 14.6 and FC in immunised ND 15.9) and SIGLE1 in the CD16− monocytes (FC in SLE 24.0 and FC in immunised ND 16.6) and the CD16+ monocytes (FC in SLE 165.0 and FC in immunised ND 62.5). This evidence concerns the gene CCL2 and systemic lupus erythematosus.
