IL4 and Parkinson disease: Also, the assessed inflammatory markers (IFN-γ, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12p70, IL-13, TNF-α) and the neurodegenerative/PD-biomarkers in CSF (Aβ1−42, t-Tau, pThr231-Tau, total α-synuclein) showed a huge overlap with the markers assessed in our study so that these 2 studies are nicely comparable.
