Research Summary

The Au lab studies cortical interneurons, a diverse population of locally-projecting GABAergic cells. They are involved in regulating spike timing, signal refinement and cortical oscillations, all of which are critical to normal brain function. We are primarily focused on how cortical interneurons wire into cortical circuitry developmentally, as well as their role in mental illness.

Our general approach is to apply developmental genetics to the differentiation of stem cells into specific interneuron subtypes. In order to study these cells in their native environment, they are transplanted in utero and we study their integration into host cortex. Since stem cells start off as a blank slate, we have the opportunity to manipulate various stages of interneuron differentiation and maturation by manipulating the cells in vitro. In this manner, we can therefore delve into molecular mechanisms that govern the process of microcircuit assembly.

Dysfunction in cortical interneurons has been linked to a number of diseases including autism spectrum disorder, schizophrenia, epilepsy and attention deficit and hyperactivity disorder. We are interested in employing stem cell-based approaches to model neuropsychiatric disorders in order to study underlying disease mechanisms. From these studies we hope to pave the way towards more directed, specific and effective treatments for psychiatric ailments.
