Iwasa K
ArXiv
. 2024 Jun;
PMID: 38903735
Outer hair cells (OHCs) are essential for the sensitivity and frequency specificity of the mammalian ear. To perform this function, OHCs need to amplify the motion of the basilar membrane...

. 2021 Dec;
423:108422.
PMID: 34965897
Avian hair cells depend on electrical resonance for frequency selectivity. The upper bound of the frequency range is limited by the RC time constant of hair cells because the sharpness...

Iwasa K
Biophys J
. 2020 Nov;
120(1):122-132.
PMID: 33248133
The effectiveness of outer hair cells (OHCs) in amplifying the motion of the organ of Corti, and thereby contributing to the sensitivity of mammalian hearing, depends on the mechanical power...

Santos-Sacchi J, Iwasa K, Tan W
J Gen Physiol
. 2019 Nov;
151(12):1369-1385.
PMID: 31676485
The outer hair cell (OHC) of the organ of Corti underlies a process that enhances hearing, termed cochlear amplification. The cell possesses a unique voltage-sensing protein, prestin, that changes conformation...

Iwasa K
Sci Rep
. 2017 Sep;
7(1):12118.
PMID: 28935970
Outer hair cells in the cochlea have a unique motility in their cell body based on mechanoelectric coupling, with which voltage changes generated by stimuli at their hair bundles drive...

Iwasa K
Biophys J
. 2016 Dec;
111(11):2500-2511.
PMID: 27926851
Electromotility of outer hair cells (OHCs) has been extensively studied with in vitro experiments because of its physiological significance to the cochlear amplifier, which provides the exquisite sensitivity and frequency...

Ospeck M, Iwasa K
Biophys J
. 2012 Jul;
102(8):1767-74.
PMID: 22768932
Recent experiments have shown a much larger conductance in outer hair cells, the central components of the mammalian cochlear amplifier. The report used only the cell's linear capacitance, which together...

Izumi C, Bird J, Iwasa K
Biophys J
. 2011 Jun;
100(11):2614-22.
PMID: 21641306
How proteins evolve new functionality is an important question in biology; prestin (SLC26A5) is a case in point. Prestin drives outer hair cell somatic motility and amplifies mechanical vibrations in...

Sul B, Iwasa K
Biophys J
. 2010 Aug;
99(4):1027-33.
PMID: 20712985
Although gating of mechanoelectrical transducer (MET) channels has been successfully described by assuming that one channel is associated with a tip link in the hair bundle, recent reports indicate that...
