To evaluate plasma cytokine profiles from HD patients and healthy controls, we quantified the plasma concentrations of interferon gamma (IFN-γ), interleukin 1 beta (IL-1β), IL-2, IL-4, IL-6, IL-8, IL-10, IL-12p70, IL-13, and tumor necrosis factor alpha (TNF-α). This evidence concerns the gene CXCL8 and Huntington disease.
