Description
How do gut microbiome-derived metabolites SCFAs LPS TMAO influence alpha-synuclein aggregation and dopaminergic neuron survival via vagal nerve signaling in Parkinson disease
Resolution criteria
Resolved when: a cited mechanistic map shows how SCFAs, LPS, and TMAO affect alpha-synuclein aggregation and dopaminergic neuron survival through vagal, immune, barrier, or metabolic signaling in Parkinson disease models. Required deliverables are KG edges for metabolite, pathway, cell/region target, and phenotype, plus a scored hypothesis or debate synthesis distinguishing direct metabolite effects from microbiome confounding.
