Another example of tangled proteins in neurodegenerative diseases

24.08.2004


Tangled strands of proteins called amyloid are found in the brain tissues of patients with a variety of neurodegenerative disorders such as Alzheimer’s disease and Parkinson’s disease. One such protein is tau, now known to participate in tangle formation in Alzheimer’s patients. Another is alpha-synuclein, whose mutations cause Parkinson’s disease and dementia with Lewy bodies. In a paper published in the current issue of the Journal of Alzheimer’s Disease, researchers from the Tokyo Institute of Psychiatry, the Tokyo Metropolitan University, and RIKEN Harima Institute show that alpha-synuclein can also enhance microtubule formation, similar to tau.



Alpha-Synuclein was originally found in Alzheimer’s disease brains by Kenji Uéda et al. Microtubules are cytoskeletal polymers essential for axonal transport and neuronal function. Writing in the article, Kenji Uéda, Ph.D., states, "Now we can see a striking resemblance between alpha-synuclein and tau: both have the same physiological function and pathological features, making abnormal structures in diseased brains known as synucleinopathies and tauopathies. The discovery of a physiological role for alpha-synuclein may provide a new dimension in researches into the mechanisms of alpha-synuclein-associated neurodegenerative diseases."

"These novel and important findings offer a new window to explore the normal physiology of these diseases" stated George Perry, editor-in-chief, JAD.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
