A high-throughput flow cytometry assay to evaluate CatSper-mediated Ca2+ influx triggered by high-K+/high-pH stimulation in mouse sperm

Lucila R. Gomez-Olivieri, Liza J. Schiavi‐Ehrenhaus, Martina Jabloñski, Mariano Gabriel Buffone, Guillermina María Luque

This paper develops a high-throughput flow cytometry assay to screen for CatSper inhibitors in mouse sperm by measuring Ca2+ influx under high-K+/high-pH conditions.

The sodium-proton exchangers sNHE and NHE1 control plasma membrane hyperpolarization in mouse sperm.

Analia G. Novero, Paulina Torres‐Rodríguez, Jose L de La Vega Beltran, Liza J. Schiavi‐Ehrenhaus, Guillermina María Luque, Micaela Carruba, Cintia Stival, Iñaki Gentile, Carla Ritagliati, Celia Maria Santi, Takuya Nishigaki, Diego Krapf, Mariano Gabriel Buffone, Alberto Darszon, Claudia Lydia Treviño, Darío Krapf

This study identifies Na+/H+ exchangers as key regulators of plasma membrane hyperpolarization in mouse sperm, challenging the role of PKA and revealing a novel pathway involving cAMP, calcium, and SLO3 K+ channels.
