Lighting the way: A new biomarker for Huntington’s disease

Lighting the way: A new biomarker for Huntington’s disease

Melissa Christianson on April 20, 2015

In Huntington’s disease, brain cells begin dying long before disease symptoms arise. Unfortunately, good tools for monitoring early brain changes – and testing whether new therapies slow or stop them – have not previously been available. However, a newly developed tool aiming to overcome this problem may mean big changes for the way we track Huntington’s disease.

Novel research technique suggests an antioxidant gene protects vulnerable neurons

Novel research technique suggests an antioxidant gene protects vulnerable neurons

Researchers have developed a new technique that allows them to screen for genes that could contribute to the progression of Huntington’s disease and other neurodegenerative disorders. This is the first time this is possible in the mammalian central nervous system. They used the technique in an HD mouse to uncover an antioxidant gene, Gpx6, which is protective to neurons.

Building a Better Mouse(trap): A New Model of Huntington’s Disease

Melissa Christianson on March 16, 2015

Most research on Huntington’s disease is done using animal models that mimic the human disease. However, these models typically recreate only a few of the disease’s symptoms, and there are some important symptoms that don’t show up in any model at all. Now, exciting new research is making great strides against these problems – and teaching us about the disease at the same time.

Taking new targets to the bank: the DNA repair protein ‘ATM’ is overactive in Huntington's disease

Taking new targets to the bank: the DNA repair protein ‘ATM’ is overactive in Huntington's disease

Terry Jo Bichell on March 09, 2015

A recent study by the Yang lab at UCLA points to a new idea for preventing damage to neurons in Huntington’s disease. The strategy is to tone down an overly helpful protein called ATM. Inside neurons, ATM provides a crucial role in repairing the cell’s infrastructure, somewhat like that of a bridge inspector, but the expanded HD protein may be causing ATM to misjudge DNA damage.

Unlocking the Potential of Antibodies as a Therapy for Huntington’s Disease

Unlocking the Potential of Antibodies as a Therapy for Huntington’s Disease

Lakshini Mendis on February 18, 2015

The growth factor 'BDNF' usually sends a “Survive!” signal to brain cells. In Huntington’s Disease (HD), this system doesn’t work as it should, so scientists have been looking for ways to boost the signal. Enter one of nature’s most useful tools: the antibody. Usually antibodies play an important role in the immune system, but researchers have identified two antibodies, produced by the company Pfizer, that can act like a set of spare keys to activate the TrkB receptor. This unlocks the door to determining whether a boost in TrkB activity is enough to prevent neurons from dying, in hopes of slowing the progression of HD.

Drug Improves Huntington’s Symptoms in Mice – and Their Offspring

Drug Improves Huntington’s Symptoms in Mice – and Their Offspring

Melissa Christianson on February 09, 2015

In Huntington’s Disease, one of the many problems arising from the disease mutation is that DNA gets folded incorrectly. A new study in mice reveals that a drug changing the way DNA folds may have beneficial effects in Huntington’s – even for the untreated offspring of treated individuals. This discovery could affect how we think about drug therapies for Huntington’s Disease.
