Accordingly, based on the magnitude of total response mounted against α-syn peptides, PD subjects were classified in two categories: responders (denoted as PD_R; > 250 SFC for the sum of IFNγ, IL-5, and IL-10) and non-responders (denoted as PD_NR; < 250 SFC). The gene discussed is IL10; the disease is Parkinson disease.
