Knock down and overexpress TSPAN7 in oligodendrocytes; measure LRRK2 kinase activity (pT73-Rab10) and lysosome position and α-synuclein uptake and myelin basic protein output under oxidative stress.
- Cell type
- oligodendrocytes
- Direction
- Both arms: public data does not say which way helps.
- Molecular readout
- LRRK2 kinase activity (pT73-Rab10) and lysosome position
- Functional readout
- α-synuclein uptake and myelin basic protein output under oxidative stress
- Rule-out
- If neither arm moves LRRK2 kinase activity (pT73-Rab10) 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 TSPAN7 in iPSC-derived oligodendrocytes; n = 3 differentiations; readouts: LRRK2 kinase activity (pT73-Rab10) and lysosome position; α-synuclein uptake and myelin basic protein output under oxidative stress. Controls: non-targeting guide, empty vector. About 8 to 10 weeks, most of it differentiation.

Swarm cases
receipt 8523: TSPAN7 in dopamine neurons, braak
- power
- full sample +0.05 (p 0.847, n 18), 95% CI -0.43 to +0.50. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.07 (p 0.787, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.15 (p 0.561, n 18). could be the mix.
- skeptic
- leave-one-out range -0.07 to +0.17, sign flips 5; without severely affected donors +0.05 (p 0.847, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for TSPAN7 in dopamine neurons.
case closed: nothing better to follow up.
