Knock down and overexpress F10 in a dopamine neuron, astrocyte and microglia tri-culture; measure LRRK2 kinase activity (pT73-Rab10) and lysosome position and dopamine neuron survival after α-synuclein fibril challenge.
- Cell type
- a dopamine neuron, astrocyte and microglia tri-culture
- Direction
- Both arms: public data does not say which way helps; existing compounds already reach the inhibition arm.
- Molecular readout
- LRRK2 kinase activity (pT73-Rab10) and lysosome position
- Functional readout
- dopamine neuron survival after α-synuclein fibril challenge
- Rule-out
- If neither arm moves LRRK2 kinase activity (pT73-Rab10) 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 F10 in a tri-culture of iPSC dopamine neurons, astrocytes and microglia; n = 3 differentiations; readouts: LRRK2 kinase activity (pT73-Rab10) and lysosome position; dopamine neuron survival after α-synuclein fibril challenge. Controls: non-targeting guide, empty vector. About 8 to 10 weeks, most of it differentiation.

Swarm cases
receipt 13279: F10 in dopamine neurons, braak
- power
- full sample -0.37 (p 0.135, n 18), 95% CI -0.71 to +0.12. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: -0.37 (p 0.127, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.45 (p 0.062, n 18). could be the mix.
- skeptic
- leave-one-out range -0.54 to -0.30, sign flips 0; without severely affected donors -0.37 (p 0.135, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for F10 in dopamine neurons.
case closed: nothing better to follow up.
