NOX2 Contributes to High‐Frequency Outer Hair Cell Vulnerability in the Cochlea

Advanced Science, EarlyView.
This study first identifies NOX2 as a differentially expressed gene related to oxidative damage in the apical and basal turns through single‐cell RNA sequencing. NOX2 gene knockout mitigates OHCs damage caused by neomycin and noise and enhances Nrf2 expression and nuclear translocation.

Consequences and Mechanisms of Noise‐Induced Cochlear Synaptopathy and Hidden Hearing Loss, With Focuses on Signal Perception in Noise and Temporal Processing

Advanced Science, EarlyView.
Noise‐induced synaptopathy (NIS) is largely reversible due to self‐repair. NIS and noise‐induced hidden hearing loss are two concepts with similarities and differences. The major hearing deficits in NIHHL are temporal processing disorders. The translation of animal data in NIS studies to humans is hindered by many factors.

Presbycusis: Pathology, Signal Pathways, and Therapeutic Strategy

Advanced Science, EarlyView.
In ARHL, the stria vascularis, acting as a cochlear battery, gradually loses its ability to maintain the endocochlear potential, leading to impaired hair cell function and progressive hearing loss. Single‐cell sequencing reveals age‐related cellular changes in the cochlea, providing insights into the underlying mechanisms of aging and potential ...

LRRC8A Regulates Outer Hair Cell Volume and Electromotility and is Required for Hearing

Advanced Science, EarlyView.
This study identifies LRRC8A‐dependent volume‐regulated anion channels (VRACs) as essential for cochlear outer hair cells' electromotility and auditory signal amplification. LRRC8A deficiency disrupts cell volume control, impairs auditory sensitivity, and causes deafness, while targeted LRRC8A re‐expression restores auditory function.

Piezoelectric Biomaterials for Bone Regeneration: Roadmap from Dipole to Osteogenesis

Advanced Science, EarlyView.
Piezoelectric biomaterials convert mechanical forces into electrical signals, offering novel strategies to restore and modulate bone microenvironments for tissue engineering. This review examines molecular dipole origins, spatial arrangements, and pseudo‐piezoelectric mechanisms and highlights dipole‐engineering techniques for osteogenesis regulation ...
