IRP Group Supports Neuropsychiatric Research

More than half of Americans are registered organ donors, signed up to gift organs like kidneys and livers to patients in need of a transplant when they die. However, far fewer people have signed up to donate their brains to biomedical research upon their deaths. At NIH, the Human Brain Collection Core (HBCC) acts as a steadfast steward of this precious and scarce scientific resource, giving the brains of deceased donors a second life as a key driver of life-changing neuropsychiatric research.

Nearly 60 million adults in the U.S. suffer from a psychiatric disorder, and examining the brains of these individuals is indispensable for determining the molecular mechanisms underlying these diseases. Consequently, the HBCC provides invaluable assistance to scientists seeking to improve our understanding and treatment of such conditions. In recognition of World Mental Health Day today, let’s take a glimpse into how the Core is accelerating investigations into the mass of gray and white matter that makes each of us who we are. 

Mouse Study Links Anxiety to Neuronal Power Failure

Chronic Stress Diminishes Energy Production in the Brain

When power lines come down and the electricity shuts off, it’s understandably a worrying situation. As it turns out, people may become anxious not just when their homes are cut off from energy, but also when their brains find themselves short on power, according to recent IRP research done in mice.

While the misfortune of a blackout is temporary, many people experience chronic stress that bothers them continuously. In some individuals, repetitive stressors can contribute to the development of debilitating anxiety that interferes with everyday life. Intriguingly, past research has found evidence that problems with the biological batteries that power our cells, called mitochondria, might be involved in anxiety disorders, as well as some other psychiatric illnesses.

In Utero Exposure to Immune Molecules May Affect Neurocognitive Development

In the midst of the 1957 Asian flu pandemic, doctors and researchers were understandably focused on treating patients and developing ways to contain the outbreak. It wasn’t until 30 years later that scientists began reporting that women who were pregnant when they caught the virus were more likely to have children who would later be diagnosed with schizophrenia.1 While that relationship remains controversial,2 numerous studies have since linked activation of a pregnant woman’s immune system with an increased risk that her child will develop certain psychiatric disorders, including not just schizophrenia but also autism spectrum disorder and major depressive disorder.3 A new IRP study has now expanded on this work by showing that exposure to higher levels of two immune system molecules in utero can noticeably alter the neurological and cognitive development of young children.4
