Knock down and overexpress SLC1A6 in dopamine neurons; measure evoked dopamine release and dopamine transporter uptake and survival of TH-positive neurons and phospho-α-synuclein (pS129) inclusions after seeding with α-synuclein fibrils.

Cell type
dopamine neurons
Direction
Both arms: public data does not say which way helps.
Molecular readout
evoked dopamine release and dopamine transporter uptake
Functional readout
survival of TH-positive neurons and phospho-α-synuclein (pS129) inclusions after seeding with α-synuclein fibrils
Rule-out
If neither arm moves evoked dopamine release by 20% or more against non-targeting and empty-vector controls, across three independent differentiations, the hypothesis is wrong.
Lab request
CRISPRi knockdown and lentiviral overexpression of SLC1A6 in iPSC-derived midbrain dopamine neurons (FOXA2+, LMX1A+, TH+); n = 3 differentiations; readouts: evoked dopamine release and dopamine transporter uptake; survival of TH-positive neurons and phospho-α-synuclein (pS129) inclusions after seeding with α-synuclein fibrils. Controls: non-targeting guide, empty vector. About 8 to 10 weeks, most of it differentiation.

Swarm cases

receipt 8108: SLC1A6 in dopamine neurons, braak

power
full sample -0.14 (p 0.591, n 18), 95% CI -0.57 to +0.35. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.15 (p 0.549, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.11 (p 0.658, n 18). could be the mix.
skeptic
leave-one-out range -0.27 to -0.03, sign flips 0; without severely affected donors -0.14 (p 0.591, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SLC1A6 in dopamine neurons.

case closed: nothing better to follow up.
