SWELL1 Chloride Channel

Cell Volume Regulation and Beyound

Molecular Biology and Physiology of Ion Transport

Chloride is the most abundant free negatively charged ion in the body. Chloride channels are cell-membrane embedded proteins, allowing the movement of chloride in and out of the cells. Defects in chloride fluxes are responsible for many human disorders, including cystic fibrosis, one of the most common genetic disease. However, we know little about some of these mysterious gate-keepers. The Qiu Lab employs a multi-disciplinary approach including high-throughput functional genomics, cell and brain slice electrophysiology, biochemistry, and mouse genetics to discover novel ion channels, elucidate their physiological role, and aim to target them in diseases, including ischemic stroke, epilepsy and glioma.


Qiu Lab, summer 2021

The Qiu Lab aims to foster a collegial and collaborative environment with a strong focus on mentoring. We are committed to a diverse and inclusive environment where all undergraduate, graduate students and postdocs can thrive and enjoy their learning opportunities as they pursue rigorous scientific research in physiology and neuroscience.
