Altered immune profile peripherally in HD. (A) Multiplex ELISA quantification of cytokine levels in plasma from HD patients (premanifest, early and moderate HD stages) compared with control subjects. Graphs show mean concentrations with standard error bars. Significant differences between individual groups are shown (ANOVA with post-hoc Tukey HSD test). (B) The overall trend for increasing levels of cytokines across all groups, analyzed using linear regression, was highly significant for IL-6 and IL-8 and significant for IL-4, IL-10, TNF-α, and IL-5. R-values (partial correlation coefficients) are corrected for age and sex. *, P < 0.05; **, P < 0.01; ***, P < 0.001; ****, P < 0.0001.
