Researchers from Imperial College London and the Hertie Institute, University of Tuebingen have identified a possible mechanism for re-growing damaged nerve fibres in the central nervous system (CNS). This damage is currently irreparable, often leaving those who suffer spinal cord injury, stroke or brain trauma with serious impairments like loss of sensation and permanent paralysis.

Adult humans continuously produce new neurons in the striatum, a brain region involved in motor control and cognitive functions, and these neurons could play an important role in recovery from stroke and possibly finding new treatments for neurodegenerative disorders, according to a study published by Cell Press February 20th in the journal Cell. To detect the birth of new neurons in the striatum, the authors used a method that measures carbon-14 found in human DNA as a result of above-ground nuclear testing more than half a century ago. The findings reveal a surprise finding of new neurons in a human brain structure where they haven't been previously described. The discovery may open up new avenues to treat diseases and disorders that affect the striatum.

Scientists at Imperial College London have discovered that iron deficiency may increase stroke risk by making the blood more sticky. The findings, published in the journal PLOS ONE, could ultimately help with stroke prevention.

The development of drugs to treat acute stroke or aid in stroke recovery is a multibillion-dollar endeavor that only rarely pays off in the form of government-approved pharmaceuticals. Drug companies spend years testing safety and dosage in the clinic, only to find in Phase III clinical efficacy trials that target compounds have little to no benefit. The lengthy process is inefficient, costly, and discouraging, says Hermano Igo Krebs, a principal research scientist in MIT’s Department of Mechanical Engineering.

Scientists from Imperial College London and two Japanese institutions explored whether physical interaction improved the way people performed in a computer-based task where they were using a joystick-like device. They were connected by a virtual elastic band to the same type of device operated by another person, who was hidden from view.

Yale researchers have identified the mechanism behind a molecular variation that reduces risk of stroke in children with sickle cell anemia. The molecular variation was recently identified but not understood due to a limited grasp of the gene’s role in hemostasis — the stopping of bleeding. These new findings open a path for the development of novel drugs that may prevent stroke, particularly in children with sickle cell anemia who are at risk of this devastating complication. The study appears online in the Journal of Biological Chemistry.
