Knock down and overexpress RPS2 in a dopamine neuron, astrocyte and microglia tri-culture; measure proteasome activity and the load of ubiquitinated protein 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
- proteasome activity and the load of ubiquitinated protein
- Functional readout
- dopamine neuron survival after α-synuclein fibril challenge
- Rule-out
- If neither arm moves proteasome 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 RPS2 in a tri-culture of iPSC dopamine neurons, astrocytes and microglia; n = 3 differentiations; readouts: proteasome activity and the load of ubiquitinated protein; dopamine neuron survival after α-synuclein fibril challenge. Controls: non-targeting guide, empty vector. About 8 to 10 weeks, most of it differentiation.
Sealed predictions

Swarm cases
receipt 12987: RPS2 in dopamine neurons, braak
- power
- full sample +0.09 (p 0.722, n 18), 95% CI -0.39 to +0.53. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.14 (p 0.591, 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 0.722, n 18). could be the mix.
- skeptic
- leave-one-out range -0.02 to +0.22, sign flips 4; without severely affected donors +0.09 (p 0.722, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for RPS2 in dopamine neurons.
case closed: nothing better to follow up.
