UCI researcher awarded nearly $4 million to study neurological disorders including epilepsy

Irvine, CA – February 28, 2019 – University of California, Irvine School of Medicine researcher Geoff Abbott, PhD, has been awarded a $2 million Outstanding Investigator Award/Maximizing Investigators’ Research Award (MIRA) R35 grant from the National Institute of General Medical Sciences, and a $1.7 million R01 grant from the National Institute of Neurological Disorders and Stroke. The MIRA grant is for a study titled, “Ion Channel Transporter Interactions,” and the R01 is for research titled, “GABA Activation of the M-current.” The 5-year grants support different studies, both focused on understanding the pathophysiology of ion channel-related disorders, including epilepsy, in search of viable therapies.

The MIRA award will support research in the Abbott Lab aimed at understanding the KCNQ and KCNE potassium channel gene families, their interactions with each other and with solute transporters. KCNQ family potassium channels are essential for the normal functioning of tissues including human heart, brain, thyroid, stomach, colon, pancreases, pituitary gland, auditory system and blood vessels, and are highly important for human health. The channels and transporters to be examined are linked to human diseases including cardiac arrhythmia, epilepsy and diabetes.

“With the help of this MIRA grant, my lab will explore how and why channel-transporter complexes form, how KCNEs and other proteins regulate these complexes, and the molecular basis for the disease processes that occur when they dysfunction,” said Abbott.

The 5-year R01 grant Abbott received will support work that follows earlier studies done by the Abbott Lab, including their discovery of the first example of a neurotransmitter directly activating a voltage-gated ion channel, and their work uncovering the molecular basis for the anticonvulsant action of specific herbal medicines.

“This grant will allow us to continue our work in an effort to uncover how prevalent and important this newly discovered mode of channel regulation is, and its potential role for pathophysiology and therapy in neurological disorders, including epilepsy,” Abbott explained.

The two studies are already underway and Abbott hopes his work will lead to the development of therapeutic agents that target the complexes to treat human disease.
