Finally, we analyzed possible correlations of PD and control RAS AA networks with major pro-inflammatory cytokines such as interleukin-17 (IL-17), interleukin-6 (IL-6), tumor necrosis factor superfamily member 14 (TNFSF14, LIGHT), tumor necrosis factor-alpha (TNF-α), and the pro-oxidative lipid marker 27-hydroxycholesterol (27-OHC), previously associated with increased risk of PD [28,29,30,31]. Here, IL17A is linked to Parkinson disease.
