Knock down and overexpress GARS1 in a dopamine neuron, astrocyte and microglia tri-culture; measure PINK1–parkin mitophagy flux (mt-Keima) and phospho-ubiquitin (pS65-Ub) 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
PINK1–parkin mitophagy flux (mt-Keima) and phospho-ubiquitin (pS65-Ub)
Functional readout
dopamine neuron survival after α-synuclein fibril challenge
Rule-out
If neither arm moves PINK1–parkin mitophagy flux (mt-Keima) 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 GARS1 in a tri-culture of iPSC dopamine neurons, astrocytes and microglia; n = 3 differentiations; readouts: PINK1–parkin mitophagy flux (mt-Keima) and phospho-ubiquitin (pS65-Ub); 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 2264: GARS1 in dopamine neurons, braak

cell type
GARS1 is not measured in dopamine neurons; looking elsewhere.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GARS1 in dopamine neurons.

case closed: nothing better to follow up.
