It appears that when our nervous system is developing, only the most viable neurons survive, while immature neurons are weeded out and die. This is shown in a ground-breaking discovery by researchers at Karolinska Institutet in Sweden. The results indicate that the long-standing neurotrophic theory, which states that chance determines which cells will form the...

Study identifies new approach to repairing damaged peripheral nervous system
UNIVERSITY OF VIRGINIA A new University of Virginia study proves that a damaged peripheral nervous system is capable of repairing itself – when healthy cells are recruited there from the central nervous system. The finding has implications for the future treatment of debilitating and life-threatening nervous system disorders affecting children, such as muscular dystrophy, Guillain-Barre Syndrome and Charcot-Marie-Tooth Disease. The study will be published in the April 2 issue of the journal Cell Reports....

Creating blood vessels on demand
by Albert Ludwigs University of Freiburg When organs or tissues are damaged, new blood vessels must form as they play a vital role in bringing nutrients and eliminating waste and it is necessary for organs and tissues to regain their normal function. At present, the injection of growth factors or genetic material into the tissue site of interest can...

Eye scan a promising option for early detection of central nervous system disorders
Partners from Austria, Germany, France and the Netherlands are taking part in the EU MOON project to develop new techniques for early diagnosis of age-related diseases of the eye and central nervous system, and successfully apply them in treatment and diagnosis. At 18 months from the start of MOON, researchers are confident that, in the...

Many RA patients’ pain related to central nervous system
(HealthDay)—Centralized pain pathways may coexist with more established peripheral inflammation-driven pathways in some patients with rheumatoid arthritis (RA), according to a study published in the July issue of Arthritis & Rheumatology. Neil Basu, M.D., Ph.D., from the University of Aberdeen in the United Kingdom, and colleagues performed an 11-minute functional connectivity magnetic resonance imaging (MRI)...

Detailed atlas of the nervous system
Researchers at Karolinska Institutet have created a systematic and detailed map of the cell types of the mouse nervous system. The map, which can provide new clues about the origin of neurological diseases, is presented in the journal Cell. The researchers will now use the same methods to map out the human brain on a detailed level. The nervous...

New stem cell model can be used to test treatments for a rare nervous system disorder
A City of Hope researcher has developed a stem cell model to assess possible treatments for a rare nervous system disorder that is in the same disease group as Alzheimer’s disease, Parkinson’s disease and amyotrophic lateral sclerosis (ALS). An Alexander disease patient’s stem cell-derived astrocytes (green) inhibits the growth of precursor cells that become myelin...

Study overturns seminal research about the developing nervous system
Left: axons (green, pink, blue) form organized patterns in the normal developing mouse spinal cord. Right: removing netrin1 results in highly disorganized axon growth. New research by scientists at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA overturns a long-standing paradigm about how axons—thread-like projections that connect...

Sympathetic nervous system key to Thermogenesis, new study suggests
The sympathetic nervous system, not white blood cells, is critically important in the regulation of energy expenditure and thermogenesis, researchers reveal in a new report. Researchers had previously hypothesized that macrophages, a class of White blood cells, played a major role in thermogenesis, however the new study suggests that the main driver of thermogenesis is...
