The cystine/glutamate antiporter system xc−, playing a critical role in the regulation of glutamate release, might be implicated in the pathogenesis of schizophrenia.
This is the first study indicating that the peripheral gene expression levels of the two system xc- subunits, SLC3A2 and SLC7A11, may be lower in patients with schizophrenia than healthy individuals.
The finding supports the hypo-glutamatergic neurotransmission hypothesis in schizophrenia.
