Ne domain. As 499-prestin retains its capability to bind cholesterol (Fig. 6d), it’s similarly affected by HPCD remedy as in WT. Our study provides a detailed characterization of prestin expression and function in OHCs within the context of NPC1 disease. Although potentially promising, our study indicates that especially targeting prestin didn’t offer protection of OHCs in response to HPCD. Future efforts for the therapy of NPC1 illness ought to incorporate efficient drug delivery to prevent cochlear exposure, development of alternative small molecules that are extra particular or non-toxic [4, 47], and gene therapy [7].Salicylate, at the doses utilised in this report, does notmitigate HPCD-induced ototoxicity in NPC1-KO mice.Further fileAdditional file 1: Figure S1.
