Scientists push forward understanding of multiple sclerosis

08.12.2005


New findings by a research team from the University of Edinburgh may help explain why diseases like multiple sclerosis (MS) which attack the myelin sheath – an insulator which protects the body’s nervous system - cause such severe symptoms in MS patients. Their discoveries may lead to new ways to help treat patients with MS, it is reported in the journal Neuron today (Thursday, 8 December).



The scientists have made an important breakthrough in understanding how animals with complex nervous systems, such as humans, achieve rapid signalling between their nerve cells. Communication between nerve cells and other organs such as muscles needs to be extremely fast, so that the body responds quickly to instructions from the brain. Electrical signals can travel rapidly from the brain because they ’jump’ down nerves using specialised hotspots called nodes.

Professor Peter Brophy of the Centre for Neuroscience Research at the Unversity and leader of the study explained: "It has been known for some time that the location of the nodes along nerves is determined by specialised cells called glia, which surround nerves with a myelin sheath. The nerves of babies are surrounded by these glial cells in the first few years after birth, which ensures proper development of the human nervous system. If nerves do not get their myelin sheath, or if they lose it later because of diseases like MS, the nodes either don’t form, or are disrupted, leading to a serious loss of nervous system function, which in turn can lead to blindness, paralysis or even death."


Professor Brophy’s team has discovered the key molecules- two proteins found in the gene Neurofascin- that link glial ensheathment of the nerve fibres to the formation of nodes. "We hope that the discovery of these proteins will help us to find ways to improve nerve conduction in patients with conditions where the myelin sheath is attacked," he said.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
