Molecular Mechanisms of Neurotransmitter-gated Ion Channels

My laboratory is broadly interested in the relationship between structure and function in neurotransmitter-gated ion channels, with special emphasis on the superfamily of nicotinic receptors. Our main tools are single-channel and ensemble electrophysiology, and protein-engineering techniques.

Some of the particular issues we have been working on lately are:

  • Quantitative characterization of fundamental properties of neurotransmitter-gated ion channels such as rate and equilibrium constants of ligand binding in the closed and open states.
  • Quantitative understanding of the different phenomena that contribute to the kinetics of the postsynaptic current decay under physiological and pathological conditions.
  • Linear free-energy relationships and the chemical dynamics of the closed-to-open conformational change.
  • Relationship between structure and electrostatics of the pore domain.
