ERVW-1 and schizophrenia: The Env protein also interacts with the sodium-dependent amino acid transporters human alanine/serine/cysteine/threonine transporter 1(hASCT1) and human alanine/serine/cysteine/threonine transporter 2 (hASCT2), disrupting glutamate uptake and contributing to excitatory/inhibitory imbalance, a central feature of schizophrenia [310,326].
