The nervous system transmits information by passing chemical signals from one nerve cell to the others. This signal transmission relies on a variety of proteins to receive and transmit the chemical signals. My group studies the structure and function of neurotransmitter receptors and ion channels that regulate fundamental neuronal activities.

Hiro Furukawa’s lab studies receptor molecules involved in neurotransmission. Its members mainly focus on the structure and function of NMDA (N-methyl-d-aspartate) receptors — ion channels that mediate excitatory transmission. Dysfunctional NMDA receptors cause neurological disorders and diseases including Alzheimer’s disease, Parkinson’s disease, schizophrenia, depression, and stroke-related ischemic injuries. The Furukawa lab is working to solve the threedimensional structure of the very large NMDA receptor by dividing it into several domains. They seek to understand the pharmacological specificity of neurotransmitter ligands and allosteric modulators in different subtypes of NMDA receptors at the molecular level. Toward this end, they use cutting-edge techniques in X-ray crystallography to obtain crystal structures of the NMDA receptor domains and validate structure-based functional hypotheses by a combination of biophysical techniques including electrophysiology, fluorescence analysis, isothermal titration calorimetry, and analytical centrifugation. Crystal structures of NMDA receptors serve as a blueprint for creating and improving the design of therapeutic compounds with minimal side effects for treating neurological disorders and diseases. During the last several years, the team discovered and mapped several regulatory sites in specific classes of NMDA receptors, progress that now opens the way to the development of a new potential class of drugs to modulate the receptor activity.

    How key brain receptor works in hostile conditions

    Cold Spring Harbor, NY — During a stroke or an epileptic seizure, neurons in affected parts of the brain fire at an abnormally rapid rate. One byproduct of this condition is that the pH of the brain drops markedly, rendering the local environment inhospitably acidic. Using a powerful microscopy method called cryo-EM, biologists at Cold...

    Portrait of a Neuroscience Powerhouse

    April 27, 2018

    At noon every Tuesday from September through June, scenes from a revolution in neuroscience are playing out at Cold Spring Harbor Laboratory. Week after week, over 100 scientists cram themselves into a ground-floor meeting room in the Beckman Laboratory. It’s standing-room only as everyone in the Neuroscience Program settles in to hear details of the...


    Can we understand memories at the molecular level?

    Can we understand memories at the molecular level?

    March 13, 2017

    LabDish blog Written by Annabel Romero Hernandez Memories may seem intangible, but many scientists are working to figure out how they are physically stored in the brain. To achieve this, we’ll need to understand memories at the molecular level. When we talk about memories, it’s usually in the context of something precious, like a beloved...

    Austin Wasielewski, born in May 2003, at first appeared to be a healthy, strong boy. About three months into his life his parents noticed his jerking motions and realized he wasn’t meeting developmental goals. On Thanksgiving Day 2003, Austin had his first myoclonic seizure. Throughout his first eight years of life he would have up...

    Drugs precisely targeting portions of this receptor may have applications in Alzheimer’s, depression and schizophrenia Cold Spring Harbor, NY — The difference between mental health and mental illness can turn on changes in brain cells and their connections that are almost incomprehensibly tiny, at least in physical terms. This irony is brought to light by...

    May 2, 2016

    Cold Spring Harbor, NY – Structural biologists at Cold Spring Harbor Laboratory (CSHL) and Janelia Research Campus/HHMI, have obtained snapshots of the activation of an important type of brain-cell receptor. Dysfunction of the receptor has been implicated in a range of neurological illnesses, including Alzheimer’s disease, Parkinson’s disease, depression, seizure, schizophrenia, autism, and injuries related...

    Biology is a question of scale. Some biologists study the large scale—populations or whole organisms. Some biologists study a medium scale, organs and tissues or even single cells. Still others may look for understanding at a smaller scale, such as cellular compartments or molecular complexes. And the biochemists study the smallest scale: molecules, and the...
