Knock down and overexpress CYBB in microglia; measure IL-1β and TNF release and surface HLA-DR 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
IL-1β and TNF release and surface HLA-DR
Functional readout
uptake and clearance of α-synuclein fibrils and NLRP3 inflammasome activation (IL-1β release)
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 CYBB in iPSC-derived microglia (iMGL); n = 3 differentiations; readouts: IL-1β and TNF release and surface HLA-DR; 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 2415: CYBB in dopamine neurons, braak

power
full sample -0.02 (p 0.949, n 18), 95% CI -0.48 to +0.45. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.05 (p 0.834, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.08 (p 0.754, n 18). could be the mix.
skeptic
leave-one-out range -0.14 to +0.10, sign flips 9; without severely affected donors -0.02 (p 0.949, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for CYBB in dopamine neurons.

case closed: nothing better to follow up.

receipt 2414: CYBB in microglia, braak

power
full sample -0.24 (p 0.341, n 18), 95% CI -0.63 to +0.26. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.28 (p 0.265, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: -0.21 (p 0.408, n 18). could be the mix.
skeptic
leave-one-out range -0.42 to -0.13, sign flips 0; without severely affected donors -0.24 (p 0.341, n 18). fragile.
cell type
