Knock down and overexpress P2RX7 in oligodendrocytes; measure IL-1β and TNF release and surface HLA-DR 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; existing compounds already reach the inhibition arm.
Molecular readout
IL-1β and TNF release and surface HLA-DR
Functional readout
α-synuclein uptake and myelin basic protein output under oxidative stress
Rule-out
If neither arm moves IL-1β 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 P2RX7 in iPSC-derived oligodendrocytes; n = 3 differentiations; readouts: IL-1β and TNF release and surface HLA-DR; 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 4449: P2RX7 in dopamine neurons, braak

power
full sample +0.18 (p 0.476, n 18), 95% CI -0.31 to +0.60. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.18 (p 0.476, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.18 (p 0.487, n 18). could be the mix.
skeptic
leave-one-out range +0.11 to +0.35, sign flips 0; without severely affected donors +0.18 (p 0.476, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for P2RX7 in dopamine neurons.

case closed: nothing better to follow up.

receipt 4448: P2RX7 in oligodendrocytes, braak

power
full sample +0.47 (p 0.047, n 18), 95% CI +0.01 to +0.77. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: +0.44 (p 0.067, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.43 (p 0.077, n 18). could be the mix.
skeptic
leave-one-out range +0.39 to +0.60, sign flips 0; without severely affected donors +0.47 (p 0.047, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for P2RX7 in oligodendrocytes.

case closed: nothing better to follow up.
