Localisation of novel forms of glutamate transporters and the cystine-glutamate antiporter in the choroid plexus: Implications for CSF glutamate homeostasis

► Multiple glutamate transporters are expressed by the choroid plexus. ► Includes sodium-dependent and sodium-independent types. ► Most glutamate transporters are expressed on the apical surface of the epithelia. ► Glutamate transporter expression may be linked mainly to GSH homeostasis.
