Merged FACS histograms showing CD14+ CD11d+ monocyte expression in 2 untreated CIDP patients (CIDP 1 and CIDP 2) compared to 2 age- and sex-matched controls (control 1 and control 2) show increased mean fluorescent intensity (MFI, a marker of receptor density) in the CIDP patients compared to controls. The tables show comparative CD11d expression data for CD14+ monocytes, CD19+ B-lymphocytes, as well as CD3+ CD4+, CD3+ CD8+ and CD3+ CD4− CD8− T-lymphocytes, suggesting a potential role in pathogenic leukocyte trafficking in CIDP.
