Brain donation programs – now perhaps at risk of losing funding – are key to a Huntington's disease cure: a family's story

 

In July 2022 Dorlue Schulte of San Diego died at home after a long struggle with Huntington’s disease. To benefit HD research, Dorlue donated her brain to the Harvard Brain Tissue Resource Center (HBTRC) at the nonprofit McLean Hospital in suburban Boston.

 

“They can get hundreds of samples from one donation, so it’s truly the gift that keeps on giving,” said Dorlue’s husband and main caregiver Doug in a presentation last October at the Huntington’s Disease Society of America (HDSA) San Diego chapter’s “Family is Everything” Education Day.

Doug observed that HD researchers are “coming up with great ways to inspect the brain to learn from them.”

“Scientists now have the ability to look at every cell in the brain and look at the mRNA and the proteins in the cells to see if they are resistant or not resistant to Huntington’s disease and, more importantly, probably, the timing of when (cell) death occurs,” Doug explained. “They’ve got to compare it with a brain that’s not diseased.”

 

For his outstanding advocacy Doug received the 2021 Woody Guthrie Award at the HDSA national convention. He served on the HDSA-San Diego board from 2019-2022. A retired firefighter, Doug has raised awareness about HD among police officers to make them “a friend, not a foe,” when encountering affected individuals.

‘Precious’ human data

 

Besides research on HD mice and many other non-human species, study of HD brains provides “precious” human data in the quest for treatments, in the words of Robert Pacifici, Ph.D., the chief scientific officer of the key, HD-focused CHDI Foundation, Inc.

 

At meetings like CHDI’s Annual HD Therapeutic Conference scientists discuss the growing body of knowledge coming from these brains.

 

Doug was inspired to present Dorlue’s story in part by Dr. Pacifici’s statements about the importance of research in humans. Although the huntingtin gene exists in many species, only humans develop HD.

 

Over 10,000 brains collected

 

Founded in 1978 and one of the first brain banks in the U.S., Harvard Brain Tissue Resource Center is one of six repositories that are part of the federal National Institutes of Health (NIH) NeuroBioBank, a centralized resource for the collection and distribution of human brain specimens for research.

  

According to the HBTRC website, it has collected over 10,000 brain donations from across the U.S. and distributed over a hundred thousand samples, both nationally and globally, that have resulted in hundreds of publications. More than 45 different brain disorders are represented in the HBTRC collection, including HD.

 

HDSA endorses HBTRC. The two have a long-standing collaboration, and HBTRC has one of the largest collections of brains donated by persons diagnosed with HD in the U.S. if not the world.

 

The HBTRC’s home, McLean Hospital, is the largest psychiatric teaching hospital of Harvard Medical School.

 

The sole funder of the HBTRC is the federal NIH, HBTRC director Sabina Berretta, M.D., wrote in an e-mail interview with me on July 25. An associate professor of psychiatry at Harvard Medical School, she carries out HD research on the team of investigator Steve McCarroll, Ph.D., whose lab has created precise techniques for measuring the impact of HD on single brain cells.

 

As Doug pointed out, this type of research is only possible because of brain donations.

 

The uncertainty of future public funding

 

Harvard University has sued the federal government to try to block the Trump administration’s freezing of nearly $3 billion in research funds. The government also seeks to eliminate $783 million in NIH funding.

 

A statement on the NeuroBioBank website reads: “This repository is under review for potential modification in compliance with Administration directives.”

 

Responding to my questions about this situation, Dr. Berretta wrote that the cuts at Harvard and the NIH have not currently impacted the HBTRC. The government has not flagged current funds, she added. She noted, however, that “we are not sure at the moment” about potential restrictions arising from government concerns about diversity, equity, and inclusion. 

 

Dr. Berretta explained that the HBTRC NIH contract “will end in October 2025. It is not known at this time whether and how the new contract, expected to start in November 2025, will be impacted.”

 

Dr. Berretta explained that “the current funding uncertainty creates some challenges, particularly for talent retention and long-term planning, both critical to our work.”

 

“The other 5 brain banks part of the NIH NeuroBioBank are in our same situation,” she added.

A family discussion and a decision

 

Dorlue was 63 and had been married to Doug for 32 years. After graduating from high school in 1976, she worked for 20 years in a Pacific Bell office. She volunteered at her church, participated in her son Ryan’s school PTA, and enjoyed family camping trips. As a young adult, Ryan tested negative for the HD gene.

 

Dorlue was remembered as having “a fighting spirit that never wavered in the face of her diagnosis” with HD, including participation in clinical trials in hopes of a cure.

 

Doug and Dorlue discussed, and then agreed to, donating her brain when she was no longer in “denial” about her disease and learning that Ryan was now free of the disease, Doug said in his presentation. Dorlue registered for the donation in 2012.

 

“It should be your decision and no one else’s,” Doug emphasized, noting that contemplating a donation can be “very stressful” because of all of the difficulties already involved in HD.

 

The decision must involve the person’s legal first of kin, who will see through the donation after the person has died.

 

There are many reasons to donate – or not donate, said Doug, noting that some might have religious reasons against the process.

 

He recommended that families start conversations about donations “early.”

 

“You can cancel at any time,” he said of the process. The opportunity to donate is “a blessing,” he added.

 

A ‘very professional’ organization

 

A person can pre-register their donation on the HBTRC website or register any time over the phone, even after an individual has died, Doug explained.

 

Doug spoke several times with Dr. Berretta.

 

“She’s very compassionate,” he said. “The organization is very professional. I really felt that they understood how difficult it was to go through that process, especially right after your loved one died.”

 

Doug noted several exclusionary criteria that might prevent a brain from being accepted, such as a delay of more than 24 hours in getting the brain to the bank; a stroke or penetrating head injury; or testing positive for HIV, hepatitis B, or hepatitis C.

 

Although “it costs a lot of money for the brain to be put on a plane and sent to Harvard,” the only charges covered by the family are the usual funeral costs, such as cremation or embalming, Doug said.

 

Just 24 hours to get the brain delivered

 

The 24-hour clock for the donation to be received starts at the moment the last person saw the deceased alive, Doug continued.

 

Dorlue died at 6 a.m., when a hospice nurse declared her dead. Doug contacted the funeral home, which needed to transport the body to the facility that “harvests” the brain. The funeral home worker took four hours to arrive, Doug said.

 

“We were ten hours into this before they even took the body out of the house,” he recalled. “I was pretty anxious that we get this thing off.”

 

The brain is packed in ice for transport and placed in the luggage area of the plane so that it stays cold throughout the flight, Doug explained.

Once it arrives at the HBTRC laboratories, the brain is immediately dissected. Part of it is immediately frozen and kept at minus 80 degrees centrigrade. Another part is immersed in formalin. It is then assessed by a neuropathologist, who generates a neuropathology report. Both preparations are made available to investigators.

 

Once the brain arrived at Harvard, Doug received a call reassuring him that it had arrived undisturbed and on time. To preserve the integrity of the tissue for research, the brain is ultimately frozen at minus 80 degrees centigrade.

 

Doug also sent the HBTRC Dorlue’s medical records to assist in their research on her brain.

 

“That’s a big part of what the scientists look at,” he said. “They compare the brain with the symptoms and see if there’s any similarities or not.”

 

Crucial work towards a cure

 

The HBTRC website has an FAQ, donation forms, and phone numbers for making a donation.

 

This HBTRC does crucial work in the quest for a cure.

 

Doug has signed up to donate his brain. I will do the same.

 

As Doug put it, the bank collects brains from around the U.S. and sends samples around the world.

 

“Who knows who’s going to find a cure,” he said.

At HDF symposium, a Huntington’s disease ‘hero’ who prays for scientists to find a cure

 

Recognizing the invaluable input from people living with Huntington’s disease, the Hereditary Disease Foundation (HDF) featured a conversation with Michael, a 62-year-old HD-affected Boston man, at its biennial conference of scientists seeking therapies for this incurable disorder.

 

Michael was interviewed about his HD symptoms by neurologist Diana Rosas, M.D., of Harvard University and Massachusetts General Hospital.

 

Titled “Living with Huntington’s Disease: Family Perspectives,” this HDF tradition of focusing on an HD-affected person took place on August 8 during HD2024: Milton Wexler Biennial Symposium. Convening some 300 researchers, biopharma officials, and advocates, the event ran August 7-10 at the Royal Sonesta Boston Hotel in Cambridge, MA.

 

HD usually impedes speech. I saw that affecting my mother. She died of the disorder at 68 in 2006, after two decades of symptoms, and I carry the HD gene.

 

Michael struggled but persistently formed words and sentences. “I pray for everybody,” Michael said, referring to the quest for therapies, during the Q&A after the interview.

 

Michael’s former wife attended in support of his advocacy, as did his two sons, both in their 20s.

A diagnosis in 2017

 

Born in Chicago, Michael grew up in Princeton, NJ. As a young adult he moved to Boston, where he studied to become a French chef. He spent a year traveling through France to master his profession. He worked in several restaurants in Boston and also at Gillette Stadium for the NFL’s New England Patriots.

 

Michael believes his father had HD, although he was never formally diagnosed, due to the limited knowledge about the disease as Michael grew up in the 1970s. His father was also an alcoholic. Michael’s aunt also suffered from HD and went into a care home.

 

Michael was diagnosed with HD in 2017.

 

It became ‘too dangerous and messy’ to cook

 

Dr. Rosas is Michael’s physician. As she noted, many lab researchers have little contact with HD-affected individuals. The interview aimed to inform them of the complex triad of symptoms and many psychosocial challenges posed by HD.

 

Dr. Rosas asked Michael to address questions about the first type of symptoms: movement disorders, including involuntary movements.

 

These symptoms, Michael explained, caused him to stop cooking: it had become “too dangerous and messy.” It also became harder to dress himself.

 

Typical of HD patients (including my mother), Michael has suffered several serious falls, leading to a broken wrist, ribs, neck, a punctured lung, and a subdural hematoma (a serious injury to the head). Though he had participated in research conducted by Dr. Rosas, the hematoma has prevented him from participating in clinical trials, because of a restriction by pharmaceutical companies.

 

“I like helping out however I can,” he said of his participation in research.

 

Michael, who lives alone, does have a chocolate labrador retriever that he walks.

 

Michael used to drink alcohol daily and smoke heavily. The drinking caused one of his falls, he said. He quit both habits. Alcohol was a “big part” of his life, he recalled, adding that he doesn’t “miss the days of drinking.”

 

A greatly modified daily routine

 

Dr. Rosas brought up another part of the HD triad: cognitive loss, executive dysfunction, and failing memory.

 

Michael observed that his loss of executive function prevented him from cooking, which had required preparing items and “lots of multitasking.”

 

Though he “can remember my bank card number,” he has ongoing difficulties with memory. He pays his cable and phone bills but has an accountant to assist with his overall finances. He still cares for two salt-water fish tanks, an activity he took up in his 20s.

 

Michael arises at 6 a.m., when he takes his medications: risperidone, an antipsychotic, twice daily; deluxotine for depression; and a multi-vitamin. He also takes medical marijuana.

 

After some small accidents, Michael stopped driving, now relying on Uber.

 

Overcoming impulsiveness and depression

 

Regarding the third part of the triad, psychiatric and mood disorders, Dr. Rosas observed that HD-affected individuals can become fixated or impulsive.

 

Michael agreed that this has affected him, recalling that his drinking also led him to be “very impulsive.” He also suffers from depression. Many HD-affected people become angry when faced with unexpected changes in their daily routine. Michael has also experienced this type of anger. Getting over the anger can take time, he added.

 

Like many of the affected, Michael also has difficulties sleeping. His drinking had exacerbated this problem.

 

“It’s like your mind and body are always on with HD,” he observed.

 

Indeed, HD-affected individuals burn lots of calories. Dr. Rosas recommends five meals per day, although Michael said he eats three to four.

‘You are a hero!”

 

In the Q&A following the interview, Michael expanded on aspects of his life.

 

One has involved his relationship with his ex-wife and sons. Michael said that the divorce occurred around the time of his diagnosis and was “probably” the result of it.

 

Michael saluted his former spouse as “one of my huge supporters. I haven’t had a girlfriend after my divorce. We were married for 24 years.”

 

He said that he has “two great kids” who are “successful and happy.”

 

Michael also socializes with friends, some of them also divorced.

 

Asked about the work of the researchers, Michael said, “I love them to death.” He added that he is looking forward to new advances.

 

Dr. Rosas asked what most worries Michael about HD.

 

“I suppose going to a home, going to an assisted living situation,” he said.

 

His capacity to manage on his own prompted praise. “You are a hero!” declared Tacie Fox, a family advocate and co-trustee of The Fox Family Foundation (which supports HD research), leading the audience to applaud enthusiastically.

 

“It feels like you have somehow navigated in a way that brings you joy in your life,” she added. “We’re struggling with that with my little sister. She watches a lot of TV. I’m in awe that you, living on your own, have marshaled that inner strength.”

 

The key role of modifier genes

 

At 64, I have been extremely fortunate to have not been diagnosed with HD. It is likely that I have benefited from modifier genes and other factors.

 

Like the rest of the audience, I was deeply moved by Michael’s courage and perseverance in living with HD.

 

I hope that when the inevitable symptoms arrive, I will have the same strength as Michael.

 

Stay tuned for upcoming articles on the conference proceedings, including deep discussion of the key role of modifier genes in the search for therapies.

Huntington’s disease community will 'get there' in search for therapies, CHDI chief scientist declares after ‘terrific’ conference

 

After presiding over a “terrific” research conference, CHDI Foundation Chief Scientific Officer Robert Pacifici, Ph.D., declared that the Huntington’s disease community will “get there” in the search for long-awaited therapies.

 

Dr. Pacifici commented in an interview with me on March 1, after the CHDI-sponsored 19th Annual HD Therapeutics Conference, held in Palm Springs, CA, from February 26-29.

 

The CHDI chief scientific officer (CSO) provided his optimistic assessment in referencing the featured presentation by David Altshuler, M.D., Ph.D., CSO of the Boston-based Vertex Pharmaceuticals.

 

“They’ve solved some unbelievably difficult problems,” Dr. Pacifici said of Vertex, noting that it found a cure for hepatitis C.

 

Vertex has also developed therapies for three tough diseases that, like HD, are genetic: cystic fibrosis, sickle cell disease, and transfusion-dependent beta thalassemia.

 

At future therapeutics conferences, “we would love for the last talk” to focus on a new drug that is “now going to be approved,’” Dr. Pacifici told me.

 

“We’re going to get there,” he continued. Dr. Altshuler, who Dr. Pacifici said carefully calibrates his optimism, “was very complimentary and very confident that if we stay on this path, we’ll actually achieve that. He felt that the collective efforts that CHDI is trying to catalyze throughout the community are going to be successful.”

 

Dr. Pacifici pointed out how CHDI has adhered to another key principle of drug discovery emphasized by Dr. Althsuler: studying HD in human cells, tissues, and postmortem samples.

 

Dr. Pacifici said he expects the HD field will hear more from Dr. Altshuler and welcomed Vertex’s possible revived involvement.

 

In 2010 I spoke on my family’s fight against HD at the Vertex labs in San Diego and chronicled its search at the time for an HD therapy, though so far without results reported by that lab.

Serbin, and posted with permission of CHDI Foundation). (Click on the image to make it larger.)

 

The need to celebrate milestones

 

“But I think what you will see is incremental successes,” Dr. Pacifici continued. “We’re going to have these new findings, these critical milestones and stepping stones along the way that we should embrace and celebrate and use those as a source of hope that, even though it never moves as fast as we would like, we’re making very real, tangible progress”

 

Dr. Pacifici described the 19th conference as “terrific,” noting that more than 450 people – a record – 50 companies, and 70 academic institutions took part. He recalled how no biopharma firms attended the first few conferences. Now such companies “come to a conference because they think an area is ripe for discovery,” he observed.

 

“Everybody commented on how quickly the conference went this year,” Dr. Pacifici said. “There was just so much information and so much happening and actually people were sad when it was over.”

 

I found this, my twelfth CHDI conference, particularly exhilarating because of the amount of new data and the high quality of the presentations.

 

A virtual nonprofit biotech, CHDI is the largest private funder of HD research. As in our interviews at past therapeutics conferences, Dr. Pacifici summarized the key findings of the scientists’ presentations. Watch our 39-minute interview in the video below.

 

 

Key developments

 

Dr. Pacifici explained several key developments.

 

The session on new data and insights into the basic biology of HD included presentations that help “to understand exactly how we can custom craft the profile of candidate drugs to make sure that they hit the right things and are as safe as possible,” Dr. Pacifici said. Such crafting would mean that drugs could effectively address the numerous specific problems in HD, he added.

 

Another session “shined a bright light” on DNA repair, modifier genes, and somatic instability, the tendency of the deleterious expansion of the DNA to worsen with age and therefore trigger disease onset, Dr. Pacifici said. The new findings can contribute to the ongoing effort to “manipulate” these processes to slow or stop instability and therefore prevent the disease, he explained.

 

Including talks detailing HD at the cellular and molecular level, the session titled “It’s a Brain Disease” was “unbelievably informative” about specifying how HD harms the brain, Dr. Pacifici said.

 

Clinical trial news and the importance of participation in research

 

The final session featured clinical trial updates from uniQure, PTC Therapeutics, and Roche. None of these has yet reached Phase 3, the definitive test of a drug.

 

Referring to the 2021 results of Roche’s first attempt at a Phase 3 trial, Dr. Pacifici noted that the firm’s scientists “have really gone to town and reanalyzed the samples, reanalyzed the data in a way that is hopefully going to teach us not only why that particular trial didn’t meet its endpoints” but also “what we can do differently.” Roche’s reassessment of its drug, tominersen, in a Phase 2 trial, GENERATION HD2, is in progress.

 

Ultimately, the field needs a “conveyor belt” of new drug possibilities to develop the multiple kinds of drugs necessary for treating different aspects of HD, Dr. Pacifici concluded. Not all those new drugs will be successful, he said, but the more produced, the greater likelihood for successful therapies.

 

Dr. Pacifici pointed out that many of the discoveries discussed at the meeting resulted from the human data collected from tens of thousands of research volunteers.

 

Future projects and breakthroughs will continue to rely on large numbers of participants, he said. Some individuals may carry unique genetic characteristics revealing new kinds of therapies.

 

“Hang in there,” Dr. Pacifici said in his closing comment for the HD community. “I hope that next year at the 20th [conference] we’ll have some more good news to communicate.”

At CHDI conference, advocates inspire acceleration of quest for Huntington’s disease therapies

 

With a record 420-plus participants, the 19th Annual Huntington’s Disease Therapeutics Conference got under way on February 26 with the aim of speeding the quest for therapies to slow, halt, or reverse the symptoms of this incurable disorder.

 

Sponsored by CHDI Foundation, Inc., the largest private funder of HD research, the event runs through February 29 at the Parker hotel in Palm Springs, CA, and will feature three days of scientific and clinical presentations.

 

“In recent years the quest for HD therapeutics that will make a real difference to affected families has accelerated and deepened,” CHDI Chief Scientific Officer Robert Pacifici, Ph.D., wrote in a welcome letter to the participants. “Accelerated in the sense that every week seems to bring new scientific insight, whether from publications or reports on new and ongoing clinical initiatives. Deepened in the sense of the sophistication of our understanding of the underlying HD biology that informs our drug development work.”

 

HD research has also “broadened,” Dr. Pacifici added, noting that participants are displaying a record 140-plus posters. Representatives from 55 pharmaceutical and biotech companies and 69 academic institutions will take part.

 

In his letter and opening remarks to the conference, Dr. Pacifici outlined how CHDI has reorganized its scientific-thematic approach to “better align” its activities “with this burgeoning body of knowledge.”

 

The conference, following such themes, will focus on new research into the roles of mutant huntingtin DNA, RNA, and protein in HD. Conference-goers also will focus on the hot topic of somatic instability, the tendency of the deleterious expansion of the DNA to worsen with age and therefore trigger disease onset.

 

A caregiver’s moving keynote and a vital TED Talk

 

Following Dr. Pacifici’s overview, the audience watched a deeply moving 80-minute keynote speech, not to be shared publicly, by Cheryl Sullivan Stavely, RN. Stavely recounted her 30-plus years as an advocate and caregiver to her late husband John and daughter Meghan, who both succumbed to HD.

 

Stavely thanked the scientists for their dedication and said she hoped that 30 years from now HD conferences will become unnecessary with the development of treatments.

 

Choking up at Stavely’s recollections of Meghan, I found the keynote highly effective in summing up the many health and social challenges faced by HD-affected people and their families such as the affected person losing the ability to work and making insurance and end-of-life arrangements.

 

Scroll to the end of this article for photos of Stavely’s presentation and others.

 

Earlier, I interviewed leading HD global advocate, Emmy Award winning television journalist, and fellow HD gene expansion carrier Charles Sabine about his compelling TED Talk “The Unlimited Capability of Every Human.” Launched on February 1, the talk already has had 4,500 views.

 

Sabine stressed the importance of making the presentation “gather viral momentum” and transform the way HD is viewed by the general public everywhere. I will explore the implications of Sabine’s vital talk in a future article.

 

Stay tuned for further coverage of the therapeutics conference.
