Researchers identify protein which could help protect against neuro-degenerative conditions

30.05.2003


Protein could be used as a treatment for Alzheimer’s, Parkinson’s, and Huntington’s disease



A team of researchers from Imperial College London, the Charing Cross Hospital and University College London have identified a protein which could be used to protect against neuro-degenerative conditions such as Alzheimer’s, Parkinson’s, Huntington’s, motor neurone diseases and the damage caused by strokes.

According to research published today in The Journal of Biological Chemistry, the researchers discovered that the naturally occurring protein, 27-kDa heat shock protein (HSP27) was able to reduce cell death in the brain.


Professor Jacqueline de Belleroche, senior author on the paper, from Imperial College London and the Charing Cross Hospital, comments: "At present, there is no cure for neuro-degenerative diseases, such as Alzheimer’s and Parkinson’s, but the discovery of the beneficial effects of this protein in the brain may provide us with a way to at least slow down the disease process."

For the experiment, the researchers used transgenic mice, which had high levels of HSP27 throughout the brain, spinal cord and other tissues. This was found to reduce mortality rate and neuronal cell death in the hippocampus, a part of the brain affected by neurological diseases. Similar results were also obtained when HSP27 was injected directly into the brain.

Professor de Belleroche adds: "Although this is unlikely to provide a cure for neuro-degenerative disorders, it could be vital in slowing their progress. Eventually it may be possible to use a drug to increase levels of HSP27 in the brain which could be given to those suffering from neuro-degenerative diseases."

Heat shock proteins (HSPs) are a group of proteins present in all cells in all life forms, and are induced when a cell undergoes environmental stresses such as heat, cold and oxygen deprivation.

They are also present in cells under normal conditions, and act like ’chaperones’ to make sure the cell’s proteins are in the right place and shape at the right time.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
