UT Southwestern researchers uncover why ketamine produces a fast antidepressant response

UT Southwestern Medical Center scientists are shedding new light on why the anesthetic drug ketamine produces a fast-acting antidepressant response in patients with treatment-resistant depression.

The drug's robust effect at low doses as a fast-acting antidepressant potentially has use in emergency rooms with high-risk patients.

"Ketamine produces a very sharp increase that immediately relieves depression," said Dr. Lisa Monteggia, associate professor of psychiatry at UT Southwestern and senior author of the study published June 15 in Nature.

Typical antidepressant medications – one of the most widely prescribed classes of drugs in the U.S. each year – often take several weeks to relieve symptoms of depression. If they are not successful within 12 weeks, physicians must prescribe a different antidepressant to produce a response.

"Ketamine produces a fast-acting antidepressant effect, and we hope our investigation provides critical information to treat depression effectively sooner," Dr. Monteggia said.

"We now have a novel pathway to explore that may provide potential for the development of faster-acting and longer-lasting antidepressants," Dr. Monteggia said.

The next step, Dr. Monteggia said, is to investigate further the short- and long-term effects of the changes that occur when the brain cells communicate with each other.

Other UT Southwestern researchers involved in the study were Anita Autry, student research assistant in psychiatry; Dr. Megumi Adachi, instructor in psychiatry; Dr. Elena Nosyreva, instructor in neuroscience; Dr. Elisa Na, postdoctoral researcher in psychiatry; Mr. Maarteen Los, visiting junior researcher in psychiatry; Mr. Peng-fei Cheng, formerly in psychiatry; and Dr. Ege Kavalali, professor of neuroscience and physiology.

The study was funded by the National Institute of Mental Health.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
