Brain cells 'talk' with each other in more ways than previously thought

Johns Hopkins scientists have discovered to their surprise that nerves in the mammalian brain's white matter do more than just ferry information between different brain regions, but in fact process information the way gray matter cells do.

Antidepressants induce new nerve cell growth in the hippocampus

The growth of new nerve cells in the hippocampus has been suggested as the way antidepressants work in rodents, says Eric Nestler, MD, PhD, of the University of Texas Southwestern Medical Center.

Increasing SUMO protein in brain could be a way of treating epilepsy and schizophrenia

The brain contains about 100 million nerve cells, each having 10,000 connections to other nerves cells. These connections, called synapses, chemically transmit the information that controls all brain function via proteins called receptors. These processes are believed to be the basis of learning and memory.

Reducing levels of the protein tau can prevent seizures and neurological deficits related to Alzheimer's disease

The findings, reported in the journal Science, demonstrate that when tau is removed from mice genetically engineered to simulate Alzheimer's disease, their memory function is retained and they live a normal lifespan. Reducing tau levels also made mice more resistant to epileptic seizures.

Green tea shows potential for HIV-associated dementia prevention

A compound derived from green tea greatly diminished the neurotoxicity of proteins secreted by the human immunodeficiency virus, suggesting a new approach to the prevention and treatment of HIV-associated dementia, also known as AIDS dementia complex.

Migraine sufferers may have form of brain damage

Scientists in the U.S. are suggesting that people with migraines may also be suffering from some form of brain damage.

Headaches may act like tiny transient strokes

Migraines may be doing more than causing people skull-splitting pain. Scientists have found evidence that the headaches may also be acting like tiny transient strokes, leaving parts of the brain starved for oxygen and altering the brain in significant ways.

Disease associated prion protein oligomers inhibit the 26S proteasome

The rogue prion proteins responsible for diseases like BSE and vCJD can destroy brain cells by blocking the protein recycling process that helps keep cells healthy.

New understanding of schizophrenia

New research helps bridge an important gap in understanding schizophrenia, providing the best evidence to date that defects in the brain's white matter are a key contributor to the disease, which affects about 1 percent of people worldwide.

Nanotechnology and biology for healing

Imagine a world where damaged organs in your body, kidneys, liver, heart, can be stimulated to heal themselves.

Cortex area thinner in youth with Alzheimer's-related gene

A part of the brain first affected by Alzheimer's disease is thinner in youth with a risk gene for the disorder, a brain imaging study by researchers at the National Institute of Mental Health (NIMH), one of the National Institutes of Health, has found.

BioForce Nanosciences sells Nano Enabler to Louisiana Tech

BioForce Nanosciences has announced the March sale of the Nano eNabler molecular printer to Louisiana Tech University in Ruston, Louisiana.

Discovery of molecular mechanism that alters strength of higher brain network connections

Yale School of Medicine and University of Crete School of Medicine researchers report in Cell April 20 the first evidence of a molecular mechanism that dynamically alters the strength of higher brain network connections.

Protein called CREB key to memory storage in brain

Scientists know little about how the brain assigns cells to participate in encoding and storing memories.

Jefferson participates in global study to extend effectiveness of drug for Parkinson's

After Parkinson's disease patients use the drug levodopa or L-dopa for several years as a treatment for restoring the cellular communication that controls muscle movement by replacing lost dopamine, they begin to experience motor complications that include a shortened response to each dose of L-dopa.

New understanding of genetics behind Noonan Syndrome

Researchers have discovered that the genetic malfunction that causes a form of mental retardation called Noonan Syndrome (NS) produces an imbalance in the genesis of two types of cells in the developing embryonic brain.

Better understanding of membrane fusion

Cells constantly swap cargo bound in vesicles, miniscule membrane-enclosed packages of proteins and other chemicals. Before the swap can take place, the vesicle membrane must fuse with another membrane, creating channels packages can pass through.

Shutting down microglia

Developing brain tumors can coax assistance from nearby cells known as microglia, according to a new study from scientists at Washington University School of Medicine in St. Louis. The researchers have identified one protein made by microglia that helps accelerate tumor growth and are looking for others.
