Abstract

Chemokines are likely to contribute to the pathogenesis of chronic inflammatory demyelinating polyneuropathy (CIDP), as evidenced by data from experimental autoimmune neuritis. The α and β chemokines in the cerebrospinal fluid (CSF) and serum from patients with CIDP were analysed using an enzyme linked immunosorbent assay. CXCL9, CXCL10, and CCL3 were raised in the CSF in CIDP compared with controls and non-demyelinating neuropathies (p < 0.001). Although the CSF levels of CCL2 were significantly higher than the serum levels for all groups, the difference between groups was not significant. CXCL9, CXCL10, and CCL3 may contribute to the pathogenesis of CIDP by recruiting inflammatory T cells and monocytes to spinal nerve roots, while CCL2 is likely to play a physiological role.
