Knock down and overexpress MAP3K14 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 MAP3K14 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 6763: MAP3K14 in dopamine neurons, braak

power
full sample -0.28 (p 0.254, n 18), 95% CI -0.66 to +0.21. 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
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.31 (p 0.211, n 18). could be the mix.
skeptic
leave-one-out range -0.42 to -0.19, sign flips 0; without severely affected donors -0.28 (p 0.254, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for MAP3K14 in dopamine neurons.

case closed: nothing better to follow up.
