🧪 Overview
Use dopaminergic-neuron-selective expression of RGS6 to distinguish true cell-autonomous rescue from broader circuit or glial effects. This is best treated as a mechanistic refinement of RGS6 rescue rather than a separate therapeutic platform, and should only advance if generic SNpc re-expression shows efficacy.

⚖️ Evidence Matrix5 supports2 contradicts
Supports
The source phenotype localizes strongly to nigral dopaminergic neurons, making cell-type-restricted rescue a clean test of whether RGS6 acts within vulnerable DA neurons.
Supports
Two for the Price of One: G Protein-Dependent and -Independent Functions of RGS6 In Vivo.
Supports
Protein Profiling of RGS6, a Pleiotropic Gene Implicated in Numerous Neuropsychiatric Disorders, Reveals Multi-Isoformic Expression and a Novel Brain-Specific Isoform.
Supports
Regulator of G protein signaling 6 (RGS6) in ventral tegmental area (VTA) dopamine neurons promotes EtOH seeking, behavioral reward and susceptibility to relapse.
Contradicts
There is no direct evidence that DA-neuron-only re-expression is sufficient to rescue established synucleinopathy; non-cell-autonomous contributions may be required.
Contradicts
The CRISPR/DIO framing adds complexity and translational burden without clear advantage over standard Cre-dependent AAV rescue.

🔮 Falsifiable Predictions (2)
pendingconf 55%
IF we selectively overexpress RGS6 exclusively in TH+ dopaminergic neurons via stereotactic AAV9-DIO-RGS6 injection in MPTP-lesioned mice (with Cre expressed only in TH+ cells), THEN stereological counts of surviving TH+ neurons in SNpc will increase by at least 40% compared to AAV9-DIO-eGFP control
Predicted outcome: TH+ neuron survival in SNpc will be significantly greater in the TH-RGS6 group (mean ≥ 40% increase vs. control), with corresponding reduction in term
Falsification: No significant difference in TH+ neuron counts between TH-RGS6 and eGFP control groups (p > 0.05), indicating cell-autonomous rescue is insufficient.

IF we compare behavioral recovery (rotarod latency and spontaneous locomotion) between MPTP mice receiving TH-neuron-restricted RGS6 rescue versus mice receiving equivalent AAV-mediated RGS6 expression restricted to cortical astrocytes (GFAP-Cre + AAV-DIO-RGS6), THEN the DA-restricted group will sho
Predicted outcome: Motor behavior will normalize in the TH-RGS6 group (≥50% recovery) but not in the GFAP-RGS6 group, confirming cell-autonomous specificity.
Falsification: The GFAP-RGS6 group shows equivalent or greater motor recovery than TH-RGS6, disproving cell-autonomous sufficiency and indicating rescue requires non-cell-autonomous mechanisms.
