Knock down and overexpress OGFRL1 in astrocytes; measure a transcriptome-wide state shift (bulk RNA-seq) and α-synuclein uptake and degradation, and dopamine neuron survival in co-culture.
- Cell type
- astrocytes
- Direction
- Both arms: public data does not say which way helps.
- Molecular readout
- a transcriptome-wide state shift (bulk RNA-seq)
- Functional readout
- α-synuclein uptake and degradation, and dopamine neuron survival in co-culture
- Rule-out
- If neither arm moves a transcriptome-wide state shift (bulk RNA-seq) 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 OGFRL1 in iPSC-derived midbrain astrocytes; n = 3 differentiations; readouts: a transcriptome-wide state shift (bulk RNA-seq); α-synuclein uptake and degradation, and dopamine neuron survival in co-culture. Controls: non-targeting guide, empty vector. About 8 to 10 weeks, most of it differentiation.

Swarm cases
receipt 2168: OGFRL1 in dopamine neurons, braak
- power
- full sample -0.14 (p 0.573, n 18), 95% CI -0.57 to +0.35. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: -0.18 (p 0.476, 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 0.465, n 18). could be the mix.
- skeptic
- leave-one-out range -0.27 to -0.07, sign flips 0; without severely affected donors -0.14 (p 0.573, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for OGFRL1 in dopamine neurons.
case closed: nothing better to follow up.
receipt 2167: OGFRL1 in astrocytes, braak
- power
- full sample +0.22 (p 0.379, n 18), 95% CI -0.27 to +0.62. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.23 (p 0.351, n 18). does not hold up.
- composition
- astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: +0.21 (p 0.398, n 18). could be the mix.
- skeptic
- leave-one-out range +0.12 to +0.36, sign flips 0; without severely affected donors +0.22 (p 0.379, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for OGFRL1 in astrocytes.
