Physiologically relevant ethanol exposure alters NRXN expression in an isoform-, splice site-, and differentiation-dependent manner, prominently affecting NRXN3 and the SS4 site. These coordinated transcriptional and proteomic changes suggest that ethanol perturbs NRXN3β-NLGN2 interactions and inhibitory synapse stability, revealing a molecular pathway where alcohol may compromise cortical network excitatory-inhibitory balance.
