SLC17A7 and hypothyroidism: Navarro et al. (33) showed that in rats with both developmental and early postnatal hypothyroidism, there were alterations within the basic hippocampal excitatory trisynaptic loop, with decreased VGluT1-ir button density in the dentate gyrus stratum distal-inner moleculare and in the CA1 hippocampal subfield stratum lacunosum-moleculare, with corresponding behavioral abnormalities.
