DNA microarray analysis is a powerful tool for simultaneous analysis and comparison of gene products expressed in normal and diseased tissues. We used this technique to identify differentially expressed genes (DEGs) in nerve biopsy samples of chronic inflammatory demyelinating polyneuropathy (CIDP) and vasculitic neuropathy (VAS) patients. We found novel previously uncharacterized genes of relevance to CIDP or VAS pathogenesis. Of particular interest in CIDP were tachykinin precursor 1, which may be involved in pain mediation, stearoyl-co-enzyme A (CoA) desaturase, which may be a marker for remyelination, HLA-DQB1, CD69, an early T-cell activation gene, MSR1, a macrophage scavenger receptor, and PDZ and LIM domain 5 (PDLIM5), a factor regulating nuclear factor (NF)-kappa B activity. Genes upregulated in VAS included IGLJ3, IGHG3, IGKC, and IGL, which all function in B-cell selection or antigen recognition of B cells. Other upregulated genes included chemokines, such as CXCL9 and CCR2, as well as CPA3, a mast cell carboxypeptidase. Allograft inflammatory factor-1 (AIF-1), a modulator of immune response was upregulated both in CIDP and VAS. Microarray-based analysis of human sural nerve biopsies showed distinct gene expression patterns in CIDP and VAS. DEGs might provide clues to the pathogenesis of the diseases and be potential targets for therapeutics.
