Developmental processes are increasingly well-characterized at the molecular and cell biological levels, but how more complex tissues and organs involving the coordinated action of multiple cell types in three dimensions is achieved remains something of a black box. One question of particular interest and importance is whether signaling interactions between neighboring tissues are essential to guiding organogenesis, or whether these can arise autonomously from developmental routines inherent...

Proteins in fluids bathing the brain are essential for building the brain, discover scientists in a report published March 10 in the journal Neuron. The finding promises to advance research related to neurological disease, cancer and stem cells. Before now, the fluid surrounding the brain was generally considered to be a sort of salt-solution that simply maintained the brain's ionic balance. Recent reports of fluctuating proteins in the fluid suggested otherwise, however. And thus, a...

The number of connections between nerve cells in the brain can be regulated by an immune system molecule, according to a new study from UC Davis. The research, published Feb. 27 in the journal Nature Neuroscience, reveals a potential link between immunity, infectious disease and conditions such as schizophrenia or autism. Schizophrenia, autism and other disorders are associated with changes in connectivity in the brain, said Kimberley McAllister, associate professor in the Center for...

A study led by Academy Research Fellow Eleanor Coffey identifies new players that put the brakes on A study led by Academy Research Fellow Eleanor Coffey identifies new players that put the brakes on. They show in mice that lack the star player "JNK1", that newborn neurons spend less time in the multipolar stage, which is when the cells prepare for subsequent expedition, possibly choosing the route to be taken. Having hurried through this stage, they move off at high speed to reach their...

The discovery of a new mechanism may have implications for a host of diseases A study from The Scripps Research Institute has unveiled a surprising mechanism that controls brain formation. The findings have implications for understanding a host of diseases, including some forms of mental retardation, epilepsy, schizophrenia, and autism. The research, led by Scripps Research Professor Ulrich Mueller, was published in the journal Neuron on February 10, 2011. In the new study, Mueller and...

In the developing brain, countless nerve connections are made which turn out to be inappropriate and as a result must eventually be removed. The process of establishing a neuronal network does not always prove precise or error free. Dr. Peter Scheiffele's research group at the Biozentrum of the University of Basel have been able to document this phenomenon using advanced microscopy techniques in the developing cerebellum, a brain area required for fine movement control. Dr. Scheiffele's group...

This finding has particular importance because several neurodevelopmental disorders have recently been linked to genetic mutations in the complex developmental cascade containing Erk and its sister proteins. Researchers at the University of North Carolina at Chapel Hill have pinpointed a crucial function for a key player in the development of the nervous system. They found that this player "“ a protein called Erk "“ is necessary for nerve fibers to be wrapped with an insulating...

The research may lead to a better understanding of diseases such as autism and schizophrenia Connected highways of nerve cells carry information to and from different areas of the brain and the rest of the nervous system. Scientists are trying to draw a complete atlas of these connections"”sometimes referred to as the "connectome""”to gain a better understanding of how the brain functions in health and disease. New research conducted at The Scripps Research Institute shows that...

Work published today shows that brain cells need to create links early on in their existence, when they are physically close together, to ensure successful connections across the brain throughout life. In people, these long-distance connections enable the left and right side of the brain to communicate and integrate different kinds of information such as sound and vision. A change in the number of these connections has been found in many developmental brain disorders including autism,...

Findings may have implications for repairing brain injury, studying diseases such as autism and brain cancer For years, the majority of research on reactive oxygen species (ROS) "“ ions or very small molecules that include free radicals "“ has focused on how they damage cell structure and their potential link to stroke, cardiovascular disease and other illnesses. However, researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research have shown for...
