Chloride binding to prestin does not influence very high-frequency complex nonlinear capacitance (cNLC) in the mouse outer hair cell

J.-P. Bai, C. Zhang, I. Bahader, N. Strenzke, V. Renigunta, D. Oliver, D. S. Navaratnam, O. Beckstein, J. Santos-Sacchi

This study shows chloride binding does not affect very high-frequency nonlinear capacitance in mouse outer hair cells, suggesting mechanical loads, not anion interactions, govern high-frequency prestin function.

Ultrasonic measures of prestin (SLC26a5) charge movements in membrane patches.

J. Santos-Sacchi, J.-P. Bai, D. S. Navaratnam

This study uses megahertz sampling to measure prestin charge movements in the ultrasonic range, finding a lower frequency roll-off and confirming a cut-off frequency near 19 kHz.

Calcium induced calcium release in proximity to hair cell BK channels revealed by PKA activation

J. Bai, N. Xue, O. Lawal, A. Nyati, J. Santos-Sacchi, D. S. Navaratnam

The paper shows that PKA activation enhances BK currents in chicken hair cells by increasing Ca2+ concentrations via CICR near BK channels.
