Knock down and overexpress C3AR1 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 C3AR1 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 8967: C3AR1 in dopamine neurons, braak
- power
- full sample -0.08 (p 0.748, n 18), 95% CI -0.53 to +0.40. 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: -0.09 (p 0.728, n 18). could be the mix.
- skeptic
- leave-one-out range -0.22 to +0.03, sign flips 3; without severely affected donors -0.08 (p 0.748, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for C3AR1 in dopamine neurons.
case closed: nothing better to follow up.
receipt 8966: C3AR1 in microglia, braak
- power
- full sample +0.25 (p 0.319, n 18), 95% CI -0.25 to +0.64. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.28 (p 0.254, n 18). does not hold up.
- composition
- microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: +0.44 (p 0.069, n 18). could be the mix.
- skeptic
- leave-one-out range +0.15 to +0.44, 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 C3AR1 in microglia.
