Research progress on the relationship between transporters in the stria vascularis and hearing loss

Stria vascularis（SV）, located in the lateral wall of the cochlea, is a highly vascularized tissue that plays a crucial role in maintaining the homeostasis of endolymph and normal auditory function, with its core function relying on the transporter system distributed within it. These transporters in the SV precisely mediate the transport of ions, nutrients, and metabolites, constituting the cornerstone of the homeostasis of endolymph. Abnormal expression or dysfunction of transporters in the SV can lead to an imbalance in the inner ear microenvironment, which can lead to hearing loss. However, the effects of transporters in SV on hearing loss have not been fully clarified. In this paper, the function and distribution of different types of transporters in SV and their relationship with hearing loss are reviewed, providing a new perspective and prospect for exploring the molecular basis of hearing loss and targeted therapies of transporters in the future.
