Researchers at the Australian Institute for Bioengineering and Nanotechnology (AIBN) are a step closer to understanding and combating the degenerative brain disease ataxia-telangiectasia.
As part of a collaborative project, Stem Cells Australia's Associate Professor Ernst Wolvetang and his research group has reprogrammed, for the first time, skin cells from people with the disease so they can study the effectiveness of potential treatments.
The reprogramming involves taking skin cells, generating pluripotent stem cells and turning them into brain cells for study in the lab.
A/Prof Wolvetang said the ability to reprogram skin cells from children with ataxia-telangiectasia provided a renewable resource to study the neurodegeneration and find medicines to combat it.
Ataxia-telangiectasia is a rare, inherited disease causing severe disability, including difficulty with movement and coordination, a weakened immune system, a predisposition to infection and a increasing the risk of cancer. People with ataxia-telangiectasia develop cancer and brain degeneration because a gene that recognises and repairs DNA damage is defective. The condition affects between one in 100,000 and one in 300,000 people. Patients are frequently in a wheelchair by their early teens and it is generally fatal by the time they reach their twenties.
