SLC17A7 and hearing loss disorder: In this study, we report that the imaging of the cochlear nerve in animal models of hearing loss can be accomplished in vivo through the utilization of immuno‐PET probe, and that 177Lu‐DOTA‐anti‐VGLUT1 can effectively evaluate the expression level of VGLUT1 in the cochlea, further visualizing the relative quantity of SGNs in mice with SGNs loss.
