£2 million study to reveal workings of dementia genes

23.09.2008
University of Manchester scientists are to investigate the biological causes of the second most common form of dementia after Alzheimer’s, thanks to a prestigious £1.9 million senior fellowship award from the Medical Research Council.

Frontotemporal lobar degeneration (FTLD) is a group of dementias that affect the frontal and temporal lobes of the brain and are characterised by behaviour and language dysfunction, rather than the memory loss associated with Alzheimer’s disease (AD).

FTLD, which affects about 50,000 people in the UK, also differs from AD in that it targets younger people: FTLD sufferers are usually in their 50s or 60s, although people as young as their 20s have also fallen victim to FTLD. AD sufferers tend to be older.

“Alzheimer’s patients lose their awareness of space and time, whereas FTLD can result in changes in personality as well as speech and language difficulties,” said Dr Stuart Pickering-Brown, who is leading the research.

“Sufferers can become apathetic or exhibit behaviour at the other extreme and lose normal social values which lead them to act inappropriately.

“Speech and language difficulties fall into two main types: sufferers can develop problems with grammar and pronunciation or have semantic dementia where they lose the information content of language.

Errors in two genes – tau and progranulin – have been identified as causes for FTLD but these only account for 10% of cases. The University of Manchester team plan to investigate the role other genes may play in the disease.

“Our research suggests other genes may be important in regulating the amount of tau and progranulin in the brain,” said Dr Pickering-Brown, who is based in the School of Translational Medicine.

“Progranulin is associated with wound healing and little is known about its function in the brain, so we now plan to study the effects of progranulin on cells and explore how it is affected by other genes.”

At the end of the five year study, the team hope to have a much clearer understanding of the genetic causes underlying FTLD.

“Understanding the biological problems that lead to FTLD will help in diagnosing the condition and ultimately allow us to find future therapies for patients.”

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
