They have been studying the impacts of nerve growth factors in the treatment of PD, and their latest results show that a certain growth factor can be used to halt the progress of damage brought on by a nerve poison and possibly even restore the function of damaged cells.
The studies on nerve growth factors used an experimental PD model in rats. Administration of the growth factor reduced motor disturbances in rats.
The severe motor disturbances that are seen in PD are caused by the slow degeneration of dopamine nerves in the brain. There are treatments that alleviate the symptoms of the disease, such as hand tremor, but they do not prevent or halt the degeneration of nerve cells. The nerve growth factors studied to date have slowed nerve cell degeneration to some extent, but they have had only limited therapeutic effect. Several known nerve growth factors, such as GDNF, also attach to extracellular tissue, possibly deterring their movement to nerve cells that require treatment.
Working under the supervision of Academy Professor Mart Saarma, scientists at the University of Helsinki Institute of Biotechnology have now been investigating two new nerve growth factors. MANF (mesencephalic astrocyte-derived neurotrophic factor) is released from glial cells in the midbrain and is a member of the same growth factor family as CDNF, another growth factor that Saarma's team have investigated. A University of Helsinki team led by Professor Raimo K. Tuominen discovered that in the experimental PD model, MANF and CDNF injections into the brain prevented dopamine nerve destruction caused by nerve poison and to some extent even restored the function of damaged cells in rats.
The latest results suggest that MANF spreads more readily in brain tissue than other known growth factors. This may be a highly significant finding in respect to the development of growth factor therapy for PD.
The results are published in the 29 July issue of the Journal of Neuroscience

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...
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...
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...

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...
