PVALB and neuroblastoma: Dysregulation of NRXNs has been linked to substance use disorders, but it remains unclear how the expression of NRXN isoforms responds to physiologically relevant amounts of ethanol.<h4>Methods</h4>Human IMR-32 neuroblastoma cells were maintained in an undifferentiated (UnDiff) state or differentiated (Diff) with trans-retinoic acid (tRA) to promote an enrichment in parvalbumin (PV) expression.
