A domain of the NR2B subunit of the NMDA receptor is mapped in exquisite detail A team of scientists at Cold Spring Harbor Laboratory (CSHL) reports on Thursday their success in solving the molecular structure of a key portion of a cellular receptor implicated in Alzheimer's, Parkinson's, and other serious illnesses. Assistant Professor Hiro Furukawa, Ph.D., and colleagues at CSHL, in cooperation with the National Synchrotron Light Source at Brookhaven National Laboratory, obtained crystal...

Scientists discover lipid may be vital to learning Saturated fats have a deservedly bad reputation, but Johns Hopkins scientists have discovered that a sticky lipid occurring naturally at high levels in the brain may help us memorize grandma's recipe for cinnamon buns, as well as recall how, decades ago, she served them up steaming from the oven. The Hopkins team, reporting Oct. 29 in Neuron, reveals how palmitate, a fatty acid, marks certain brain proteins "“ NMDA receptors "“...

Glutamate is to the brain like coffee is to our bodies. A cup of Joe in the morning can wake us, but overloading on caffeine causes the stimulant to work against us. Glutamate is the major excitatory neurotransmitter in a mammal's central nervous system. It is an important component for neuroplasticity, the synaptic communication between neurons. It's also key to learning and memory. But in high concentrations, glutamate becomes toxic-- over-exciting the neurons. Glutamate-induced...

One hundred years ago, Kikunae Ikeda discovered the flavor-giving properties of glutamate, a non essential amino acid traditionally used to enhance the taste of many fermented or ripe foods, such as ripe tomatoes or cheese. New research now reveals that the tongue has a receptor that is exclusively activated by glutamate. "Although other receptors have been found on the tongue that are also aroused by glutamate, they are not specific. That is, they need to be in contact with nucleotides and...

A new study by researchers at Wake Forest University School of Medicine may reveal how long-lasting memories form in the brain.The researchers hope that the findings, now available online and scheduled to appear in an upcoming issue of Neuroscience, may one day help scientists develop treatments to prevent and treat conditions such as post-traumatic stress disorder."Although many things are known about memories that form from repeat experiences, not much is known with regard to how some...

Drugs that block a growth factor receptor on brain cells may prevent epilepsy after brain damage, according to a new study appearing in the July 15 issue of The Journal of Neuroscience.Daniela Kaufer, an assistant professor of integrative biology at the University of California, Berkeley, graduate student Luisa P. Cacheaux, and their Israeli colleagues, graduate student Yaron David and neurosurgeon Alon Friedman, found that they could prevent the brain changes leading to epilepsy in rats by...

U.S. researchers suggest a protein found in vegetables -- glutamic acid -- may lower blood pressure. The study, published in Circulation: Journal of the American Heart Association, found a 5 percent higher dietary intake of glutamic acid as a percentage of total dietary protein was correlated with small reductions in blood pressure. Lead author Dr. Jeremiah Stamler of the Feinberg School of Medicine at Northwestern University in Chicago said it is estimated that reducing a population's...

Using a combination of sensory, genetic, and in vitro approaches, researchers from the Monell Center confirm that the T1R1-T1R3 taste receptor plays a role in human umami (amino acid) taste.They further report that variations in the genes that code for this receptor correspond to individual variation in sensitivity to and perceived intensity of umami taste."These findings bolster our understanding of human taste variation and individual differences in tastes for essential nutrients," says...

The latest work to 'turn off the taps' in the brain and stop a chemical being released in excess amounts "“ which can lead to Parkinson's Disease "“ will be presented at The British Pharmacological Society's Summer Meeting in Edinburgh today (Wednesday, 8 July 2009).Dr Susan Duty from King's College London will present her latest work, aimed at stimulating 'trigger points' to stop the release of a chemical that can kill brain cells, at a special symposium that focuses on research...
