Pro-inflammatory cytokines are emerging as neuroinflammatory mediators in Parkinson's disease (PD) due to their ability act through neuronal cytokine receptors. Critical questions persist regarding the role of dysfunction and contribution PD pathology. Specifically, potential synergy hallmark protein alpha-synuclein (α-syn) with is interest. We therefore investigated direct impact pro-inflammatory on neurons hypothesized that α-syn pathology exacerbates cytokine-induced deficits PD. iPSC-derived cortical (CNs) from healthy controls patients gene locus duplication (SNCA dupl) were stimulated IL-17A, TNF-α, IFN-γ, or a combination thereof. For rescue experiments, CNs pre-treated anti-oligomerisation compound NPT100-18A prior IL-17A stimulation. Cytokine receptor expression, microtubule cytoskeleton, axonal transport activity assessed. SNCA dupl displayed an increased expression impaired IL-17A-mediated regulation. Cytokines exacerbated altered distribution tubulin post-translational modifications neurites, dupl-specific effects.
