Research Summary

Research in the Kavanaugh laboratory focuses on the roles of transporters, receptors, and ion channels in the brain. The work integrates electrophysiological, molecular, and behavioral approaches. The overarching goal of the lab is to understand the structure, function, and biophysical properties of these membrane proteins in order to link molecular properties to cellular and circuit level functions.

In the brain, neurons communication by synaptic transmission, which occurs when neurotransmitter is released into the synaptic cleft between two neurons. Glutamate is the major excitatory neurotransmitter in the brain, and when it binds to postsynaptic receptors it activates electrical signals leading to processes ranging from perception to learning and memory. Following activation of postsynaptic receptors, neurotransmitter is cleared away by selective transporters which terminate signaling.

Research in Kavanaugh’s lab has helped establish principles for how the transporters for glutamate and other neurotransmitters work, and how they cooperate with ion channels to regulate synaptic signaling in both normal and disease processes. In collaboration with synthetic chemists, the team is also developing and testing new drugs that target transporters for therapeutic and diagnostic applications.

The Prion Disease Database (PDDB) is a public database that supports the prion disease research community by collecting, integrating, and presenting data from public sources and collaborating laboratories. The PDDB was originally created by the Institute for Systems Biology and the McLaughlin Research Institute, which have researched prion disease using a systems biology approach.
