IF we engineer a KIF5A adaptor protein containing a LC3-interacting region (LIR) fused to a pathological seed-recognizing domain and express it in motor neurons derived from ALS/FTD patients with TDP-43 pathology, THEN we will observe a ≥40% reduction in cytoplasmic TDP-43 aggregates and a ≥2-fold i
Predicted outcome: ≥40% reduction in TDP-43 aggregate burden; ≥2-fold increase in lysosomal co-localization
Falsification: No significant change in TDP-43 aggregation patterns (<20% reduction) and no change in lysosomal trafficking metrics compared to empty vector controls

IF we administer a single intrathecal injection of AAV9 encoding an engineered KIF5A adaptor with lysosomal targeting domains to 8-week-old SOD1G93A mice (a model of ALS), THEN we will observe delayed onset of hindlimb paralysis by ≥10 days and a ≥50% reduction in spinal cord motor neuron inclusions
Predicted outcome: Delayed disease onset by ≥10 days; ≥50% reduction in motor neuron inclusions
Falsification: No significant difference in disease onset (difference <5 days) or no reduction in aggregate burden in motor neurons compared to GFP control group
