8:26 – G'day from Melbourne! The World Congress on Huntington’s disease has begun. Stay tuned for Jeff and Ed’s science news updates

8:33 – Ed and Jeff are reporting from the opening session

8:36 – Ed: Prof Julie Stout opens the meeting and welcomes the most international audience ever at a World Congress

8:55 – Ed: Peter Harper recaps the history of HD & highlights the sharing of successes and challenges between scientists & family members

9:60 – Jeff: Peter Harper encourages us to remember that the HD community has been pioneers of how patient communities can serve each other

9:16 – Jeff: “Everyone can play a part in helping to bring a cure closer” – Peter Harper.

9:27 – Jeff: Real treatments are in development. Hopefully new trials within 24 months. – Sarah Tabrizi

9:37 – Ed: Sirtuin-1 inhibitor drug that may help cells get rid of mutant protein being tested in patients now

9:39 – Jeff: Pharma giant Pfizer hopes to test a novel compound in HD patients within 24 months. – Sarah Tabrizi

9:47 – Ed: Tabrizi announces the Track-HD battery of tests to enable us to run clinical trials in early HD to test new drugs

9:50 – Jeff: Despite brain atrophy, HD mutation carriers don’t do worse over 24 months on mental or motor tasks – TRACK HD results

10:40 – Ed: Tabrizi announces TrackOn-HD, a new international study of how the brains of HD gene carriers compensate for the genetic mutation

10:15 – Don’t forget we’ll put your questions to top HD researchers live at the end of the day. Tweet them or email [email protected]

10:41 – Ed and Jeff now reporting from “clinical research” session

10:48 – Ed: Re-analysing data about ‘normal’ and ‘expanded’ CAG length casts doubt on any relationship between the two – Prof Jim Gusella

10:50 – Ed: Expanded alleles are still bad- but a person’s ‘lower’ CAG score doesn’t seem to matter

11:10 – Jeff: Whole genomes of HD patients are now being sequenced to look for changes associated with early or late symptom onset

11:30 – Jeff: Jim Gusella – slime mold have a Huntingtin gene, and we can learn what the gene normally does by studying it

11:15 – Jeff: PREDICT-HD has 10 years of brain imaging from 657 subjects, allowing investigators to understand how HD changes brains

11:16 – Ed: MRI scans can pick up widespread brain changes as far as 15 years before symptom onset- Elizabeth Aylward/PREDICT-HD study

11:30 – Jeff: HD patients with different symptoms – psychiatric, movement or thinking – have different shaped brains – Elizabeth Aylward

11:42 – Jeff: Tony Hannan tells us that making the lives if mice more exciting improves HD symptoms

11:49 – Ed: HD mice that are more active have chemical and gene control changes that improve the connections between neurons

11:59 – Ed: could drugs mimic or enhance the beneficial effects of staying active in HD? Tony Hannan is working on it

12:17 – Ed: Colin Masters studies harmful proteins in Alzheimer’s & thinks lessons learned in AD could help us to crack Huntington’s

12:20 – Ed: Huntingtin protein binds to copper atoms. Drugs that affect this might alter how harmful the protein is. Trial being planned

12:24 – Ed: Prana Biotech 12-site study of PBT2 drug aiming to reduce HD damage by influencing copper levels, starting late 2011 in Aus & USA

13:37 – Ed now reporting from session on ‘Clinical care: youth and young’. Jeff’s in the ‘Basic science: therapeutic strategies’ session

13:51 – Jeff: Isis pharma has three separate strategies to reduce levels of the mutant Huntington protein, all looking good!

13:58 – Ed: We’re only just discovering how the brain develops during teenage years. This needs to be studied in HD- Dr Nicholas Allen

14:00 – Jeff: Short-term treatment of HD mice with drugs that reduce mutant Huntington levels has long term benefit – Don Cleveland

14:12 – Ed: Visit hdyo.org – the HD youth organisation, launching Jan ‘12. International support network for young people affected by HD

14:16 – Ed: HDYO will provide info for kids, teens, young adults & parents – translated into several languages

14:37 – Ed: Moving testimonies from HD family members. People’s ability to remain strong against extraordinary adversity never fails to amaze

14:45 – Ed: Euro-HD network survey of young ppl reveals lack of support and info about many aspects of life with HD, HDYO.org will help

15:00 – Jeff: Xiao-Jiang Li is moving beyond mice, making pig and monkey models of HD

Latest Research Articles

Two birds, one stone: HTT-lowering drugs also target CAG expansions

Published date: 21 May, 2024

Huntingtin (HTT)-lowering and somatic expansion have been two of the hottest topics in Huntington’s disease (HD) research in the past decade. Recent work from a team at Massachusetts General Hospital detailed a serendipitous overlap between the two – certain HTT-lowering drugs can also help regulate the ongoing CAG repeat expansion. Seemingly, this could allow researchers ... Read more

Hats off to brain donors on Brain Donation Awareness Day

Published date: 7 May, 2024

If you’re a frequent reader of HDBuzz, you may have noticed that our articles increasingly thank Huntington’s disease (HD) families for their generous and selfless brain donations. That’s because more and more research is making use of human brains, leading to a better understanding of HD in people. All of that is only possible because ... Read more

A sprinkling of good news for the treatment of HD chorea

Published date: 3 May, 2024

We wrote in August of 2023 about the US approval of a new drug to treat chorea, the movement symptoms of HD. That drug, valbenazine, commercially known as INGREZZA, has just been approved in a new format, one that can be added to soft foods. This news deserves a brief HDBuzz mention. Chorea control Valbenazine ... Read more

HDBuzz strives to be an honest and neutral source of information that Huntington’s disease (HD) families can turn to for trusted, unbiased reporting on research and clinical trial news. We’re honored to have become a global resource for the HD community over the years (14!) and we look forward to building upon the original mission ... Read more

How many is too many? Exploring the toxic CAG threshold in the Huntington’s disease brain

Published date: 21 April, 2024

Drug hunters have been particularly interested in the repeating C-A-G letters of genetic code that lead to Huntington’s disease (HD). The number of CAG repeats gets bigger in vulnerable brain cells over time and may hold the key for slowing or stopping HD. Many scientists have been asking what happens to HD symptoms if we ...
