Knock down and overexpress P2RY6 in microglia; measure a transcriptome-wide state shift (bulk RNA-seq) and uptake and clearance of α-synuclein fibrils and NLRP3 inflammasome activation (IL-1β release).

Cell type
microglia
Direction
Both arms: public data does not say which way helps.
Molecular readout
a transcriptome-wide state shift (bulk RNA-seq)
Functional readout
uptake and clearance of α-synuclein fibrils and NLRP3 inflammasome activation (IL-1β release)
Rule-out
If neither arm moves a transcriptome-wide state shift (bulk RNA-seq) 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 P2RY6 in iPSC-derived microglia (iMGL); n = 3 differentiations; readouts: a transcriptome-wide state shift (bulk RNA-seq); uptake and clearance of α-synuclein fibrils and NLRP3 inflammasome activation (IL-1β release). Controls: non-targeting guide, empty vector. About 8 to 10 weeks, most of it differentiation.

Swarm cases

receipt 8121: P2RY6 in dopamine neurons, braak

power
full sample -0.51 (p 0.032, n 18), 95% CI -0.79 to -0.05. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.55 (p 0.018, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.67 (p 0.0023, n 18). not the mix.
skeptic
leave-one-out range -0.61 to -0.44, sign flips 0; without severely affected donors -0.51 (p 0.032, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for P2RY6 in dopamine neurons.

case closed: nothing better to follow up.

receipt 8120: P2RY6 in microglia, braak

power
full sample -0.40 (p 0.099, n 18), 95% CI -0.73 to +0.08. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.34 (p 0.164, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: -0.34 (p 0.161, n 18). could be the mix.
skeptic
leave-one-out range -0.53 to -0.31, sign flips 0; without severely affected donors -0.40 (p 0.099, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for P2RY6 in microglia.

case closed: nothing better to follow up.
