Erbin protein critical to brain excitement

Scientists have found an early step in how the brain's inhibitory cells get excited. A natural balance of excitement and inhibition keeps the brain from firing electrical impulses randomly and excessively, resulting in problems such as schizophrenia and seizures. However excitement is required to put on the brakes.

Klotho protein plays important role in the health of myelin

Researchers at Boston University School of Medicine (BUSM) led by Carmela Abraham, PhD, professor of biochemistry, along with Cidi Chen, PhD, and other collaborators, report that the protein Klotho plays an important role in the health of myelin, the insulating material allowing for the rapid communication between nerve cells.

Study illuminates the response of dopaminergic neurons to changes in temperature

While the wooly musk ox may like it cold, fruit flies definitely do not. They like it hot, or at least warm. In fact, their preferred optimum temperature is very similar to that of humans-76 degrees F.

Biomaterials as neural stem cell niches can help repair damage in the CNS

Despite recent advances in understanding the mechanisms of nerve injury, tissue-engineering solutions for repairing damage in the central nervous system (CNS) remain elusive, owing to the crucial and complex role played by the neural stem cell (NSC) niche. This zone, in which stem cells are retained after embryonic development for the production of new cells, exerts a tight control over many crucial tasks such as growth promotion and the recreation of essential biochemical and physical cues for neural cell differentiation.

Androgens could constitute an efficient treatment against multiple sclerosis

Testosterone and its derivatives could constitute an efficient treatment against myelin diseases such as multiple sclerosis, reveals a study by researchers from the Laboratoire d'Imagerie et de Neurosciences Cognitives, in collaboration in particular with the "Neuroprotection et Neurorégénération: Molécules Neuroactives de Petite Taille" unit.

IL-13 protein could be the key to development of fibrosis in Crohn's disease

New research has shown that a protein, known as IL-13, could be the key to the development of fibrosis in Crohn's disease. This breakthrough could help to advance new medicines to treat people suffering with the disease.

MiR-182 deeply involved in memory formation within the amygdala brain structure

It takes a lot to make a memory. New proteins have to be synthesized, neuron structures altered. While some of these memory-building mechanisms are known, many are not. Some recent studies have indicated that a unique group of molecules called microRNAs, known to control production of proteins in cells, may play a far more important role in memory formation than previously thought.

Scientists discover functional control strategies in emotional circuits of people with social phobia

Fear is a protective function against possible dangers that is designed to save our lives. Where there are problems with this fear mechanism, its positive effects are cancelled out: patients who have a social phobia become afraid of perfectly normal, everyday social situations because they are worried about behaving inappropriately or being thought of as stupid by other people.

Clarient adopts QIAGEN’s therascreen KRAS test to diagnose colorectal cancer

QIAGEN N.V. today announced that Clarient - a GE Healthcare Company and leading provider of cancer laboratory testing services in the United States - has adopted the use of the therascreen KRAS RGQ PCR Kit (therascreen KRAS test) as a companion diagnostic to guide the use of Erbitux (cetuximab) as a treatment in patients with metastatic colorectal cancer.

MDGA proteins associated with autism suppress inhibitory synapse formation

Synapse development is promoted by a variety of cell adhesion molecules that connect neurons and organize synaptic proteins. Many of these adhesion molecules are linked to neurodevelopmental disorders; mutations in neuroligin and neurexin proteins, for example, are associated with autism and schizophrenia.

Brain areas work together at the same time to recall memories

Working with patients with electrodes implanted in their brains, researchers at the University of California, Davis, and The University of Texas Health Science Center at Houston (UTHealth) have shown for the first time that areas of the brain work together at the same time to recall memories. The unique approach promises new insights into how we remember details of time and place.
