Knock down and overexpress PLPPR1 in oligodendrocytes; measure glucocerebrosidase (GCase) activity and LC3-II and p62 flux 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
- glucocerebrosidase (GCase) activity and LC3-II and p62 flux
- Functional readout
- α-synuclein uptake and myelin basic protein output under oxidative stress
- Rule-out
- If neither arm moves glucocerebrosidase (GCase) activity 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 PLPPR1 in iPSC-derived oligodendrocytes; n = 3 differentiations; readouts: glucocerebrosidase (GCase) activity and LC3-II and p62 flux; 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 1257: PLPPR1 in dopamine neurons, braak
- power
- full sample +0.30 (p 0.221, n 18), 95% CI -0.19 to +0.67. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.30 (p 0.221, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.22 (p 0.374, n 18). could be the mix.
- skeptic
- leave-one-out range +0.25 to +0.47, sign flips 0; without severely affected donors +0.30 (p 0.221, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for PLPPR1 in dopamine neurons.
case closed: nothing better to follow up.
receipt 1256: PLPPR1 in oligodendrocytes, braak
- power

- composition
- oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.35 (p 0.153, n 18). could be the mix.
- skeptic
- leave-one-out range +0.30 to +0.52, sign flips 0; without severely affected donors +0.38 (p 0.120, n 18). fragile.
