Axon terminals of VGLUT2-positive excitatory neurons extending from the inferior colliculus to multiple brain regions show high expression levels of DPP10 (Fujimoto et al., 2021) that, compared to other FXS NPCs, was the most significantly increased transcript in HEL100.2 NPCs throughout the sampling period (Figure 5C). Here, SLC17A6 is linked to fragile X syndrome.
