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.

Antisense therapy shows promise in treating toxoplasmosis

A targeted approach to treating toxoplasmosis, a parasitic disease, shows early promise in test-tube and animal studies, where it prevented the parasites from making selected proteins. When tested in newly infected mice, it reduced the number of viable parasites by more than 90 percent, researchers from the University of Chicago Medicine report in the Proceedings of the National Academy of Sciences.

Targeting elevated HLX gene expression may treat acute myeloid leukemia

Scientists at Albert Einstein College of Medicine of Yeshiva University have made a discovery involving mice and humans that could mean that people with acute myeloid leukemia (AML), a rare and usually fatal cancer, are a step closer to new treatment options. Their study results were published online today in Cancer Cell.

Ingredient for butter flavor in microwave popcorn is a respiratory hazard

The ingredient 2,3-pentanedione (PD), used to impart the flavor and aroma of butter in microwave popcorn, is a respiratory hazard that can also alter gene expression in the brain of rats. Manufacturers started using PD when another butter flavoring, diacetyl, was found to cause bronchiolitis obliterans, a life-threatening and nonreversible lung disease in workers who inhaled the substance.

Researchers discover gene mutations linked to spinocerebellar ataxia

A global hunt for the cause of a crippling inherited nerve disorder has found its target. The discovery opens the door for better diagnosis and treatment of this particular disease - but also for better understanding of why nerves in the brain's movement-controlling center die, and how new DNA-mapping techniques can find the causes of other diseases that run in families.

Latrepirdine demonstrates new potential against neurodegenerative conditions

The second of two studies on latrepirdine, recently published in Molecular Psychiatry, demonstrates new potential for the compound in the treatment of Alzheimer's disease, Parkinson's disease, sleep disorders, and other neurodegenerative conditions. An international team led by Mount Sinai School of Medicine scientists found that latrepiridine, known commercially as Dimebon, reduced the level of at least two neurodegeneration-related proteins in mice.

Epigenetic factors involved in treatment-resistance to schizophrenia drugs

Researchers at Mount Sinai School of Medicine may have discovered why certain drugs to treat schizophrenia are ineffective in some patients. Published online in Nature Neuroscience, the research will pave the way for a new class of drugs to help treat this devastating mental illness, which impacts one percent of the world's population, 30 percent of whom do not respond to currently available treatments.

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.

Leukoaraiosis modifies brain function in the elderly

Researchers at the Mayo Clinic say a common condition called leukoaraiosis, made up of tiny areas in the brain that have been deprived of oxygen and appear as bright white dots on MRI scans, is not a harmless part of the aging process, but rather a disease that alters brain function in the elderly.

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.

Reducing copper in the body delays onset of prion disease

Many of us are familiar with prion disease from its most startling and unusual incarnations-the outbreaks of "mad cow" disease (bovine spongiform encephalopathy) that created a crisis in the global beef industry. Or the strange story of Kuru, a fatal illness affecting a tribe in Papua New Guinea known for its cannibalism. Both are forms of prion disease, caused by the abnormal folding of a protein and resulting in progressive neurodegeneration and death.
