DPP6-linked neuronal regulatory networks controlling synaptic excitability and cognitive resilience in PD as proximal driver in DPP6 GWAS Signal: Cell-Type Regulatory Networks for PD Cognitive Decline
🧪 Overview
DPP6-linked neuronal regulatory networks controlling synaptic excitability and cognitive resilience in PD should produce a measurable proximal phenotype before late disease pathology. The decisive test is cell-type eQTL colocalization, enhancer perturbation, and prodromal PD single-nucleus validation in hippocampal and prefrontal neurons.
