UCP2 uncoupling protein occurs mainly in cells of the immune system

When uncoupling proteins are active, mitochondria produce heat instead of ATP. This may be useful under certain circumstances, such as when an animal is hibernating. But non-hibernating animals also have them. Particularly poorly understood is the uncoupling protein UCP2. Elena Pohl and colleagues at the University of Veterinary Medicine, Vienna, show that the protein occurs mainly in cells of the immune system.

Pulvinar regulates communication between clusters of brain cells

A mysterious region deep in the human brain could be where we sort through the onslaught of stimuli from the outside world and focus on the information most important to our behavior and survival, Princeton University researchers have found.

Biomedical engineer devises new noise model that is closer to the biological reality

Biomedical engineer Muhammet Uzuntarla from Bulent Ecevit University, Turkey, and his colleagues present a biologically accurate model of the underlying noise which is present in the nervous system.

Study uncovers new pathway that can treat depression

Depression takes a substantial toll on brain health. Brain imaging and post-mortem studies provide evidence that the wealth of connections in the brain are reduced in individuals with depression, with the result of impaired functional connections between key brain centers involved in mood regulation. Glial cells are one of the cell types that appear to be particularly reduced when analyzing post-mortem brain tissue from people who had depression.

Catechins may help reduce neurological complications linked to HIV

Current drug therapy for patients with HIV is unable to control the complete replication of the virus in the brain. The drugs therefore do not have any effect against the complications associated with neurocognitive impairment in patients with HIV. New research by Joseph Steiner and colleagues from Johns Hopkins University has discovered that a group of plant polyphenols known as catechins, which naturally occur in green tea and the seed of the cacao tree, may help in the prevention of these neurological complications.

Schizophrenia and the immune system: an interview with Prof Cyndi Shannon Weickert

Schizophrenia is the most disabling disease impacting youth today. It impacts 1% of the total population and typically causes withdrawal from society, loss in IQ, disordered thought and speech, hallucinations and delusions.

External stimulation impacts postnatal development of brain's white matter

A team at Children's National Medical Center has found that external stimulation has an impact on the postnatal development of a specific region of the brain. Published in Nature Neuroscience, the study used sensory deprivation to look at the growth and collection of NG2-expressing oligodendrocyte progenitor cells (NG2 cells) in the sensory cortex of the brain.

Chronic nerve pain: researchers identify which sensory nerve cells are responsible

New research, led by academics at the University of Bristol and published in the journal Pain, has identified the subtypes of sensory nerve cells that are likely to contribute to long-term nerve pain from partial nerve injury. It is hoped this will aid in development of more effective pain killers.

Scientists discover why major depression or chronic stress can cause loss of brain mass

Major depression or chronic stress can cause the loss of brain volume, a condition that contributes to both emotional and cognitive impairment. Now a team of researchers led by Yale scientists has discovered one reason why this occurs - a single genetic switch that triggers loss of brain connections in humans and depression in animal models.

Scientists discover how pten gene causes brain changes that lead to autism-like behavior

Scientists affiliated with the UC Davis MIND Institute have discovered how a defective gene causes brain changes that lead to the atypical social behavior characteristic of autism. The research offers a potential target for drugs to treat the condition.

Research on language gene seeks to uncover origins of the singing mouse

Singing mice (Scotinomys teguina) are not your average lab rats. Their fur is tawny brown instead of the common white albino strain; they hail from the tropical cloud forests in the mountains of Costa Rica; and, as their name hints, they use song to communicate.

Effects on white matter brain volume from long-term alcoholism are different for men and women

(Boston) - Researchers from Boston University School of Medicine (BUSM) and Veterans Affairs (VA) Boston Healthcare System have demonstrated that the effects on white matter brain volume from long-term alcohol abuse are different for men and women. The study, which is published online in Alcoholism: Clinical and Experimental Research, also suggests that with abstinence, women recover their white matter brain volume more quickly than men.

Manipulating hormone-producing cells in the brain may help control blood sugar levels

Manipulating a group of hormone-producing cells in the brain can control blood sugar levels in the body - a discovery that has dramatic potential for research into weight-loss drugs and diabetes treatment.

Two major classes of brain cells repress neural activity in specific mathematical ways

The brain has billions of neurons, arranged in complex circuits that allow us to perceive the world, control our movements and make decisions. Deciphering those circuits is critical to understanding how the brain works and what goes wrong in neurological disorders.

Astrocytes help reduce damaging effects of epilepsy

Epileptic fits are like thunderstorms raging in the brain: Nerve cells excite each other in an uncontrolled way so that strong, rhythmic electrical discharges sweep over whole brain regions. In the wake of such a seizure, the nerve cells are severely affected, and permanent damage is possible. The glia, a class of cells that surround the neurons in the brain, was long suspected to contribute to the damaging effects of epilepsy.

Scientists discover biological marker that may help identify patients’ response to antidepressants

Scientists have discovered a biological marker that may help to identify which depressed patients will respond to an experimental, rapid-acting antidepressant. The brain signal, detectable by noninvasive imaging, also holds clues to the agent's underlying mechanism, which are vital for drug development, say National Institutes of Health researchers.

Studies in mice reveal how mood-altering drugs may affect brain stem cells

Working with mice, Johns Hopkins researchers say they have figured out how stem cells found in a part of the brain responsible for learning, memory and mood regulation decide to remain dormant or create new brain cells. Apparently, the stem cells "listen in" on the chemical communication among nearby neurons to get an idea about what is stressing the system and when they need to act.

Similar molecular pathways involved in intellectual disability due to Fragile X and Down syndromes

Intellectual disability due to Fragile X and Down syndromes involves similar molecular pathways report researchers in The EMBO Journal. The two disorders share disturbances in the molecular events that regulate the way nerve cells develop dendritic spines, the small extensions found on the surface of nerve cells that are crucial for communication in the brain.

Anacardic acid can rescue some ALS phenotypes in vitro

A research group at the Center for iPS Cell Research and Application (CiRA) at Japan's Kyoto University has successfully recapitulated amyotrophic lateral sclerosis (ALS)-associated abnormalities in motor neurons differentiated from induced pluripotent stem cells (iPSCs) obtained from patients with familial ALS, a late-onset, fatal disorder which is also known for Lou Gehrig's disease. In a drug screening assay using the disease model, the team further found that the chemical compound anacardic acid can rescue some ALS phenotypes in vitro.

B-cell substances may play a role in MS progression

Wayne State University School of Medicine researchers, working with colleagues in Canada, have found that one or more substances produced by a type of immune cell in people with multiple sclerosis (MS) may play a role in the disease's progression. The finding could lead to new targeted therapies for MS treatment.
