Significantly elevated levels of isotype-switched anti-PLP antibodies are present in MS patients. (A) Reactivity in ELISA of healthy individuals' (HC), MS and OND patients' sera (all tested at 1/40 dilution) to PLP181−230, synthesized with 2 disulphide bonds to mimic the structure of the second extracellular loop of PLP. Results are presented as the normalized PLP181−230-specific absorbance values. Analyzed using Kruskal–Wallis test with Dunn's multiple comparison test. (B) Percentage of samples of each isotype from individuals with elevated (at or above the 75th percentile of the HC group) antibodies reactive to PLP. n.s., not significant.
