对大多数哺乳动物来说,声源在方位角上的定位是至关重要的,它利用了声音信号在时间和/或强度上的耳间差异。利用两耳到达时间和/或强度的微小差异,需要在听觉系统中传播的电脉冲在时间上是精确的。在这项研究中,我们发现消除听觉细胞中特别丰富的GluA4蛋白会显著损害其忠实传递电信号的能力,导致小鼠对声音刺激的听觉反应严重缺陷。因此,我们得出结论,GluA4对于在听觉回路中实现高保真的信息流是必不可少的。我们的工作已经确定了GluA4作为潜在的候选分子参与人类听力缺陷和障碍。
Non‐technical summary  Localization of sound sources in the azimuth, which makes use of interaural differences in timing and/or intensity of acoustic signals, is of vital importance for most mammals. Using the small differences in time of arrival and/or intensity at the two ears requires that propagation of electric pulses in the auditory system be temporally precise. In this study, we found that elimination of GluA4, a protein particularly abundant in auditory cells, significantly impairs their ability to faithfully transmit electric signals, leading to profound deficits in auditory responses to sound stimuli in mice. Therefore, we conclude that GluA4 is indispensable for enabling information flow with high fidelity in the auditory circuitry. Our work has identified GluA4 as a potential molecular candidate involved in human hearing deficits and disorders.
