Huajun Feng, PhD

The Feng Laboratory at Mass General studies the modulation of ion channels by general anesthetics using molecular biology, biochemistry andelectrophysiology techniques. The laboratory also researches the mechanism and treatment of epilepsy and seizures as well as their related complications.

Research Areas

  • Molecular mechanism for general anesthetics
  • GABAA receptor function and pharmacology
  • Mechanism and treatment of epilepsy/seizures

Description of Research

We study modulation of ion channels by general anesthetics using molecular biology, biochemistry and electrophysiology techniques.  Wild type and mutant GABAA receptors are expressed in heterologous expression systems, and allosteric modulation of GABAA receptors by anesthetics such as etomidate is investigated using two electrode voltage-clamp and patch-clamp recordings.  We are also interested in studying the mechanisms underlying epilepsy/seizures as well as their related complications.  In the current project, we are investigating the role of serotonergic neurotransmission in respiratory arrest evoked by generalized seizures in DBA mice, an animal model for human sudden unexpected death in epilepsy (SUDEP).
