Compared with NF155<sup>-</sup> CIDP, CXCL8/IL-8 and IL-13 were significantly higher, and IL-1β, IL-1ra, and IL-6 were lower, in NF155<sup>+</sup> CIDP.
In both cohorts, MSRV-env and -pol transcripts, IL6 positivity prevalence and CXCL10 levels were significantly elevated in CIDP patients when compared to HBDs and ONDs (statistically significant in all comparisons).
Furthermore, IL-6 mRNA expression was significantly parallel to both binding and signal-transducing receptor expression, implying a role of the IL-6 signal for non-neuronal cells in CIDP.
