Cell research opens new avenues in combating neurodegenerative diseases
Date:7/20/2012

ollect not only at the tip of microtubules but also along the shaft, which helps to stabilise them and ensure they act as a stable structure within the axon.

This additional function of spectraplakins relates them to a class of microtubule-binding proteins including Tau. Tau is an important player in neurodegenerative diseases, such as Alzheimer's, which is still little understood. In support of the author's findings, another publication has just shown that the human spectraplakin, Dystonin, causes neurodegeneration when affected in its linkage to microtubules.

Talking about his research Dr Prokop said: "Understanding cytoskeletal machinery at the cell level is a holy grail of current cell research that will have powerful clinical applications. Thus, cytoskeleton is crucially involved in virtually all aspects of a cell's life, including cell shape changes, cell division, cell movement, contacts and signalling between cells, and dynamic transport events within cells. Accordingly, the cytoskeleton lies at the root of many brain disorders. Therefore, deciphering the principles of cytoskeletal machinery during the fundamental process of axon growth will essentially help research into the causes of a broad spectrum of diseases. Spectraplakins like at the heart of this machinery and our research opens up new avenues for its investigation"

What Dr Prokop's paper in the Journal of Neuroscience also demonstrates is the successful research technique using the fruit fly Drosophila. The team was able to replicate its findings regarding axon growth in mice which in turn means the findings can be translated to humans.

Dr Prokop points out fruit flies provide ideal means to make sense of these findings and essentially help to unravel the many mysteries of neurodegeneration.

Dr Prokop continues: "Understanding how spectraplakins perform their cellular functions has important implications for basic as well as biomedical research. T
