Knock down and overexpress CTF1 in a dopamine neuron, astrocyte and microglia tri-culture; measure IL-1β and TNF release and surface HLA-DR 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.
- Molecular readout
- IL-1β and TNF release and surface HLA-DR
- Functional readout
- dopamine neuron survival after α-synuclein fibril challenge
- 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 CTF1 in a tri-culture of iPSC dopamine neurons, astrocytes and microglia; n = 3 differentiations; readouts: IL-1β and TNF release and surface HLA-DR; 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 2151: CTF1 in dopamine neurons, braak
- power
- full sample -0.29 (p 0.246, n 18), 95% CI -0.67 to +0.21. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: -0.24 (p 0.346, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.25 (p 0.310, n 18). could be the mix.
- skeptic
- leave-one-out range -0.41 to -0.20, sign flips 0; without severely affected donors -0.29 (p 0.246, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for CTF1 in dopamine neurons.
case closed: nothing better to follow up.
