Combine subthreshold RGS6 rescue with D2-pathway modulation to test whether benefit requires convergent normalization of autoreceptor-Gi/o signaling. This remains secondary to monotherapy studies and should not be prioritized until RGS6-alone efficacy and the relevant signaling mechanism are established.
Restore RGS6 in substantia nigra pars compacta dopaminergic neurons after established alpha-synuclein pathology to test whether RGS6 loss is not only necessary but therapeutically reversible. The decisive experiment is delayed intervention in PFF or AAV-SNCA models with unbiased stereology, terminal preservation, dopamine physiology, and catalytically dead RGS6 controls.
