Huntington’s disease research news. In plain language. Written by scientists. For the global HD community.
It’s a great mystery why different people with the same HD mutation sometimes develop symptoms at vastly different ages. Last year a huge genetic analysis gave us some interesting clues, and now, researchers are focusing in on the most promising results. A recent study shows that tiny changes within genes that repair damaged DNA can have a big effect on age of onset in HD and related diseases.
Cognitive deficits, or difficulties thinking clearly, often appear well before the traditional clinical diagnosis of Huntington’s disease (HD). While many contend that the earliest cognitive deficits are caused by damage to the striatum – a structure deep in the brain known to be severely affected in HD – recent evidence suggests that this claim may paint an incomplete picture of the widespread changes occurring in the brains of HD patients during the very early stages of the disease.
A recent article in the UK newspaper the Daily Telegraph has HD families very excited. The title, "First drug to reverse Huntington’s disease begins human trials", certainly sounds exciting! But what's really going on? HDBuzz is here to help us untangle hope from hype in the huntingtin lowering world.
After an exciting day of science yesterday, day 2 saw updates on strategies to rid cells of the harmful mutant huntingtin protein and exciting reports on current and planned clinical trials.
The third and final day of the 2016 Huntington's Disease Therapeutics Conference brings updates on cell replacement therapies including stem cells; and new ways to assess and model the progression of HD to help understand it and run crucial clinical trials.
If it's February, that means the the world's leading scientists are converging on Palm Springs for the annual HD therapeutics conference!
Recent days have seen a torrent of news stories about a new technology, called CRISPR, which has been described as having potential application in Huntington's disease. Is this new technique as cool as it sounds? Possibly — but, as always, the truth is more complicated than the headlines suggest.
New therapies for disorders like Huntington’s disease are on the way, but getting the drugs to enter brain cells can be a major challenge. A group of scientists has redesigned and tested a harmless virus that can efficiently deliver a 'gene silencing' message throughout the brain in mice, much further than naturally occurring viruses can reach. What's more, it can be given with a simple injection into the blood, offering great potential for research in gene silencing research and beyond.
Common depictions of HD emphasizing only its movement symptoms paint an incomplete picture of the real disease. HD causes both motor and non-motor symptoms that, together, affect the entire body. Now, scientists are using a broader lens to explore this full set of HD symptoms and determine how symptoms might be related in the disease.
