Knock down and overexpress C1QA 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 C1QA 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 12753: C1QA in dopamine neurons, braak
- power
- full sample -0.25 (p 0.319, n 18), 95% CI -0.64 to +0.25. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: -0.23 (p 0.355, 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 0.471, n 18). could be the mix.
- skeptic
- leave-one-out range -0.33 to -0.15, sign flips 0; without severely affected donors -0.25 (p 0.319, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for C1QA in dopamine neurons.
case closed: nothing better to follow up.
receipt 12752: C1QA in microglia, braak
- power
- full sample -0.17 (p 0.504, n 18), 95% CI -0.59 to +0.32. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: -0.17 (p 0.504, n 18). does not hold up.
- composition
- microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: -0.08 (p 0.741, n 18). could be the mix.
- skeptic
- leave-one-out range -0.33 to -0.05, sign flips 0; without severely affected donors -0.17 (p 0.504, n 18). fragile.
- cell type
- no other cell group does better.
