Mouse studies offer new insights about cocaine’s effect on the brain

Newly discovered beetle species named after Rockefeller’s Daniel KronauerResearchers have determined how a specific protein regulates the brain’s response to cocaine. Their findings provide fresh insights into the neurobiology of addiction, and could lead to the development of better interventions and treatments.

Study offers insight on how a new class of antidepressants works

Study offers insight on how a new class of antidepressants worksThe experimental drugs target brain cells’ ability to respond to the chemical messenger glutamate, however, it has been unclear how they work. The recent discovery of a molecular amplification system helps explain how the drugs alter signaling in particular neurons to achieve an antidepressant effect. More »

A newly discovered molecular feedback process may protect the brain against Alzheimer’s

A newly discovered molecular feedback process may protect the brain against Alzheimer’s Researchers have identified within neurons a series of molecular interactions — known as a pathway — that can dampen the production of the Alzheimer’s protein amyloid-β. These results suggest a new route in the search for therapies for this degenerative disease. More »

New research sheds light on the molecular origins of Parkinson’s disease

New research sheds light on the molecular origins of Parkinson’s diseaseScientists have identified two proteins that appear to have a protective effect in the set of neurons most affected by this degenerative disease. When the activity of these molecules wanes, disease sets in. This discovery suggests new avenues for preventing or treating Parkinson’s. More »

Anti-inflammatory drugs reduce effectiveness of SSRI antidepressants

Scientists have shown that anti-inflammatory drugs, which include ibuprofen, aspirin and naproxen, reduce the effectiveness of the most widely used class of antidepressant medications, the selective serotonin reuptake inhibitors, or SSRIs, often prescribed for depression and obsessive-compulsive and anxiety disorders.

Molecule that spurs cell’s recycling center may help Alzheimer’s patients

A molecule that activates the cell’s natural recycling program may flush away the protein fragments that accumulate and form senile plaques in Alzheimer’s disease. New research suggests that stimulating this activity, either through drugs or natural processes, may improve the quality of life for people with diseases caused by built-up proteins in the brain.

MicroRNAs play a role in cocaine addiction

MicroRNAs, short stretches of RNA that silence genes, have already been linked to cancer, heart disease and mental disorders such as schizophrenia. New research by Rockefeller University scientists suggests microRNAs are also involved in regulating the motivation to consume cocaine, a finding that could ultimately lead to new ways of combating addictive diseases in humans.

Alzheimer’s brain protein may provide target for treating mental retardation

Reducing the level of β-amyloid, a protein found in the brains of patients with Alzheimer’s disease and Down syndrome, may improve the cognitive abilities of children with Down syndrome. The new study by Rockefeller University scientists may provide a model for developing new anti-amyloid drugs. More »

Mouse model reveals a cause of ADHD

New research in a mouse model of attention deficit/hyperactivity disorder suggests that the root of the psychiatric disorder might be the over-activity of a protein that regulates the brain’s reward-motivation system. The work suggests a path toward new treatments for symptoms including inattentiveness, over-activity and impulsivity. More »

Loss of epigenetic regulators causes mental retardation

New findings, published in recent issues of Neuron and Science, indicate that malfunction of a protein complex that normally suppresses gene activation causes mental retardation in mice and humans and may even play a role in promoting susceptibility to drug addiction. More »
