However, the number of glutamatergic terminals, which was estimated based on vesicular glutamate transporter 1 (VGLUT1)-IR, was unaffected in the CA1 (p = 0.54) and DG (p = 0.60) of the AD rats compared to control rats (Fig. 8B, right panel). This evidence concerns the gene SLC17A7 and Alzheimer disease.
