In roundworms, the sodium-potassium pump helps position acetylcholine receptors at nerve-muscle connections, even when it’s not actively moving ions, suggesting it has a structural role in organizing synaptic signaling.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
A systematic review could determine whether Na+/K+-ATPase subunits consistently localize near neurotransmitter receptors across species, supporting a conserved scaffolding function.
A systematic review and meta-analysis of all studies using immunofluorescence, super-resolution microscopy, or proteomics to assess co-localization of Na+/K+-ATPase subunits with nAChRs, AMPARs, or NMDARs in neurons across C. elegans, Drosophila, rodents, and humans.
An RCT in C. elegans could determine whether targeted disruption of EAT-6’s scaffolding domain (without affecting pump activity) disrupts receptor clustering.
A randomized, controlled experiment in 100 C. elegans expressing EAT-6 mutants with intact ATPase activity but disrupted receptor-binding domains, randomized to receive wild-type or mutant transgenes, measuring nAChR clustering (fluorescent tagging), synaptic transmission (electrophysiology), and locomotion.
A cohort study could determine whether C. elegans with EAT-6 mutations show progressive synaptic dysfunction over development.
A longitudinal cohort study tracking 50 C. elegans with EAT-6 mutations and 50 wild-type controls from larval stage to adulthood, measuring nAChR cluster density (live imaging), synaptic vesicle release (FM dye), and locomotion speed at daily intervals.
A case-control study could determine whether human neurons with ATP1A3 mutations show altered receptor clustering compared to controls.
A case-control study comparing induced pluripotent stem cell-derived human neurons from 20 patients with ATP1A3 mutations and 20 controls, measuring nAChR and AMPAR clustering (super-resolution microscopy) and synaptic density (electron microscopy).
A cross-sectional study could identify correlations between Na+/K+-ATPase expression and receptor clustering in fixed tissue samples.
A cross-sectional analysis of 40 human postmortem cortical tissue samples, measuring co-localization of ATP1A3 and GluA2 subunits using immunofluorescence and Pearson’s correlation coefficient.
