Research Interests

In the brain, neurons communicate 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 receptors on postsynaptic neurons, it activates signaling processes ranging from perception to learning and memory. GABA is the major inhibitory neurotransmitter in the brain and it plays a key role in modulating and opposing the excitatory glutamate signaling. Homeostasis, or long-term control of neurotransmitter actions, reflects a complex balance of synaptic release and reuptake of those neurotransmitters.

Research in Kavanaugh's lab has involved identifying and characterizing a number of transporters and channels. This work has helped reveal principles governing how the transporters for glutamate, GABA, and other neurotransmitters work, and how they cooperate with ion channels to regulate synaptic signaling in both normal and disease processes. With the human genome project nearing completion, the role of mutations and polymorphisms in many human neurological diseases is becoming apparent. In collaboration with academic and pharma partners, the team is also pursuing preclinical research using transgenic mouse models to develop and test new drugs including RNA-targeting synthetic oligonucleotides and engineered viruses.

Projects

The Kavanaugh lab is engaged in research directed towards understanding and developing therapies for neurological diseases that result from mutations in genes expressed in the brain. Many of these projects involve the use of transgenic mice that harbor mutations recapitulating human neurodegenerative diseases. These model animals are studied using behavioral, biochemical, and electrophysiological approaches. Several of these projects are focused on preclinical development of novel potential therapeutic approaches based on RNA targeting strategies.

Current projects include: 
1) studies of the transporter for the major GABA transporter SLC6A1 and the mechanism of mutations that lead to autism and epilepsy 
2) studies on the role of the recently identified D-serine transporter SLC1A4 and its role in homeostasis of NMDA receptor signaling in health and disease
3) studies on the mechanisms involved in Alzheimer's disease and genetic risk factors for disease
