A genome wide search for genes underlying anxiety disorders turned up unexpected candidates

La Jolla, CA – Increasing the activity of two enzymes better known for their role in oxidative stress metabolism turns normally relaxed mice into 'Nervous Nellies,' according to research conducted at the Salk Institute for Biological Studies and reported in the early online edition of Nature.

Your brain cells may 'know' more than you let on by your behavior

La Jolla, CA – We often make unwise choices although we should know better. Thunderstorm clouds ominously darken the horizon. We nonetheless go out without an umbrella because we are distracted and forget. But do we? Neurobiologists at the Salk Institute for Biological Studies carried out experiments that prove for the first time that the brain remembers, even if we don't and the umbrella stays behind. They report their findings in the Oct. 20th issue of Neuron.

Brain's response to visual stimuli shaped by interaction of inhibitory and excitatory neurons, helping us to focus on what we should see, rather than all there is to see

La Jolla, CA – Delving ever deeper into the intricate architecture of the brain, researchers at The Salk Institute have now described how two different types of nerve cells, called neurons, work together in tiny sub-networks to pass on just the right amount and the right kind of sensory information.

Scientific institute founded by vaccine pioneer Jonas Salk to host meeting for polio survivors on Oct. 27

La Jolla, CA – Polio survivors – who were afflicted with poliomyelitis in the years or months before the vaccine to prevent this often-crippling disease became available in 1955 – are invited to attend a special symposium, at 3 p.m., Thursday, Oct. 27, at the Salk Institute for Biological Studies.

Silencing Alzheimer's: targeting a key enzyme with gene therapy reversed course of disease in mouse models

La Jolla, CA – In mice, that had been genetically engineered to develop Alzheimer's disease, scientists were able to reverse the rodents' memory loss by reducing the amount of an enzyme that is crucial for the development of Alzheimer's disease.

Key regulator of blood glucose levels discovered

La Jolla, CA – In many patients with type 2 diabetes, the liver acts like a sugar factory on overtime, churning out glucose throughout the day, even when blood sugar levels are high. Scientists at the Salk Institute for Biological Studies discovered a key cellular switch that controls glucose production in liver cells.

Unexpected features of anthrax toxin may lead to new types of therapies

La Jolla, CA – Surprising new insights about the acid pH levels required for anthrax toxin to invade the cells of the body may help accelerate development of medications for the treatment of anthrax, a disease caused by a spore-forming bacterium.

'Fail safe' mechanism that helps keep inflammation in check

La Jolla, CA – Shutting down a master activator of the body's inflammatory response – which is the goal of several experimental drugs now in development for the treatment of arthritis – may create even more inflammation with its associated pain and swelling in the body.

Tiny roundworm's telomeres help scientists to tease apart different types of aging

La Jolla, CA – The continual and inevitable shortening of telomeres, the protective "caps" at the end of all 46 human chromosomes, has been linked to aging and physical decline. Once they are gone, so are we. But there are more ways than one to grow old.
