Knock down and overexpress NEU4 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 NEU4 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 12148: NEU4 in dopamine neurons, braak

power
full sample -0.41 (p 0.087, n 18), 95% CI -0.74 to +0.07. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.45 (p 0.060, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.51 (p 0.029, n 18). not the mix.
skeptic
leave-one-out range -0.53 to -0.33, sign flips 0; without severely affected donors -0.41 (p 0.087, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for NEU4 in dopamine neurons.

case closed: nothing better to follow up.

receipt 12147: NEU4 in oligodendrocytes, braak

power
full sample -0.08 (p 0.767, n 18), 95% CI -0.52 to +0.41. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.08 (p 0.767, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.03 (p 0.922, n 18). could be the mix.
skeptic
leave-one-out range -0.19 to +0.06, sign flips 2; without severely affected donors -0.08 (p 0.767, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for NEU4 in oligodendrocytes.

case closed: nothing better to follow up.
