Knock down and overexpress CLN3 in microglia; measure glucocerebrosidase (GCase) activity and LC3-II and p62 flux 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
glucocerebrosidase (GCase) activity and LC3-II and p62 flux
Functional readout
uptake and clearance of α-synuclein fibrils and NLRP3 inflammasome activation (IL-1β release)
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 CLN3 in iPSC-derived microglia (iMGL); n = 3 differentiations; readouts: glucocerebrosidase (GCase) activity and LC3-II and p62 flux; 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 3713: CLN3 in dopamine neurons, braak

power
full sample -0.13 (p 0.621, n 18), 95% CI -0.56 to +0.36. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.10 (p 0.696, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.07 (p 0.787, n 18). could be the mix.
skeptic
leave-one-out range -0.29 to -0.05, sign flips 0; without severely affected donors -0.13 (p 0.621, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for CLN3 in dopamine neurons.

case closed: nothing better to follow up.

receipt 3712: CLN3 in microglia, braak

power
full sample -0.09 (p 0.709, n 18), 95% CI -0.54 to +0.39. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.09 (p 0.728, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: -0.04 (p 0.888, n 18). could be the mix.
skeptic
leave-one-out range -0.20 to +0.02, sign flips 3; without severely affected donors -0.09 (p 0.709, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for CLN3 in microglia.
