Interestingly, Devos et al. (2013) reported the inflammatory responses in the gut since the early stages of PD, by analyzing the ascending colonic biopsies of PD patients, they found that the pro-inflammatory cytokines (TNF-α, IF-γ, IL-6, and IL-1β) and glia markers GFAP and Sox-10 were significantly elevated, and some of them (IL-6, IL-1β, and Sox-10) were negatively correlated with disease duration. Here, SOX10 is linked to Parkinson disease.
