My long-term objective is to discover new drugs for treating addiction to drugs of abuse and alcohol. Currently, there are few FDA approved drugs for treating these diseases and more are greatly needed. Many of the neurotransmitters in the drug-reward pathway exert their effects by activating G protein-coupled receptors, which, in turn, communicate with specific G proteins and affect down-stream signaling pathways. One of the down-stream targets is the G protein-gated inwardly rectifying potassium (GIRK) channel, which we study in my laboratory. By controlling the membrane excitability of neurons, GIRK channels provide a fundamental source of neuromodulatory inhibition in the brain. My laboratory has been addressing fundamental questions concerning the function of GIRK channels in the brain, taking a broad approach of combining structural biology, biochemistry, electrophysiology and behavior. We have contributed significant work on the mechanism underlying G protein-regulation and gating of GIRK channels, provided evidence for the assembly of GIRK channels in macromolecular signaling complexes, and identified novel proteins that regulate GIRK channels. More recently, we have elucidated the subcellular mechanisms underlying the neuroplastic changes in GIRK channel signaling with drugs of abuse and alcohol.

Molecular studies of GIRK channels and Alcohol
The alcoholic beverages we consume contain ethanol. Alcohol consumptions can lead to dependence, and eventually alcohol use disorder (AUD). Ethanol produces complex effects on the body, primarily through its interactions within the central nervous system. How ethanol alters neuronal circuits in the brain and causes AUD is poorly understood. Unlike drugs of abuse, ethanol produces a wide range of pharmacological effects on the nervous system, ranging from anxiolytic to intoxication, and has a number of different targets in the brain. One of the targets for ethanol is GIRK channels. GIRK channels are G protein-activated potassium channels that control the excitability of neurons. We are investigating the structural mechanism underlying alcohol-dependent activation of GIRK channels and the role of these channels in alcohol-related behaviors. We are taking an innovative approach of using structural biology to guide screening and selection of novel therapeutics, and validating drug effects with ex vivo and in vivo systems. We recently identified and characterized a new GIRK modulator, called GiGA1. We are also using cryoEM to study the structural mechanism underlying activation of GIRK channels and GABA(B) receptors by different ligands.

Drug addiction and the reward circuit
Psychostimulants, such as methamphetamine and cocaine, are highly addictive, and abused by millions of people. Recent work from our laboratory has established that drug exposure reduces slow inhibition, mediated by GABA(B) receptors that activate GIRK channels. We have delineated two different mechanisms of drug-dependent plasticity in VTA neurons. In GABA neurons, psychostimulant-dependent depression of GABA(B)-GIRK currents involves de-phosphorylation of the GABA(B) R2 receptor via the protein phosphatase PP2a. In DA neurons, psychostimulant-dependent depression of GABA(B)-GIRK currents involves the GIRK3 subunit and an endosomal trafficking protein SNX27. We are currently examining the role of GIRK channels in projection specific VTA neurons using chemogenetics (i.e. DREADDs), and searching for new GIRK regulatory proteins using BioID. To develop new therapeutics for treating addiction, it is essential to elucidate the components of drug-dependent plasticity in the brain and discover novel protein targets in the reward pathway.

Monitoring neuromodulator release and action in real-time
As part of the NIH Brain Initiative, our lab is actively involved in developing new innovative neurotechniques for optically dissecting the function of neuromodulators in the brain of awake animals. We have created cell-based biosensors (CNiFERs) to optically measure the release of neuropeptides in cell-specific and circuit-specific processes in the brain, in collaboration with the Kleinfeld laboratory at the Univ. of California, San Diego. CNiFERs detect nM concentrations of transmitter, have a temporal resolution of seconds, and a spatial resolution of < 100 μm. In collaboration with Qin laboratory at the Univ. of Texas at Dallas, we are developing a technique of photo-releasing peptides and other modulators in the brain with two photon precision. In combination with CNiFERs, we can begin to understand the diffusion of peptides in the brain.
Studies of human diseases using hiPSCs
Excessive alcohol use is one of the top 10 contributors to disability worldwide, and an estimated 16 million Americans meet the criteria for alcohol use disorders (AUD). AUD is heritable (50-60%), polygenic and results from the contributions of genes and environment. We are part of a multi-institution research program, called the Collaborative Studies on the Genetics of Alcoholism (COGA), supported by the National Institute of Alcohol Abuse and Alcoholism (NIAAA). COGA’s primary goal is to identify the genes that increase or decrease the risk of alcoholism. Our laboratory is using human induced pluripotent stem cell (hiPSC)-based models to study the effect of risk genes on the functional activity of human neurons, to better understand the role of genetics in AUD.

Schizophrenia, bipolar disorder and autism are common and debilitating neurodevelopmental disorders that together affect more than 5 million Americans. Despite more than fifty years of research, no cures exist, and the standard of treatment remains unsatisfactory. Heterozygous mutations of neurexin-1 (NRXN1) have been repeatedly associated with schizophrenia (SZ) and autism spectrum disorder (ASD). In collaboration with Dr. Brennand, we are investigating how NRXN1+/- deletions perturb the NRXN1 isoform repertoire and impact neuronal maturation and synaptic function, using experimental manipulations of control and NRXN1+/- patient-derived excitatory and inhibitory neurons.
