Niche Disorder: Huntington’s Disease by Alison D. Center


Huntington’s disease (HD) is a fatal genetic disorder that causes a progressive breakdown of nerve cells in a sufferer’s brain. The associated HTT gene makes the “huntingtin” protein, which appears to be important for neuron function and is essential for prenatal brain development. The HTT gene contains a particular CAG (cytosine, adenine, and guanine) trinucleotide repeat DNA segment that normally repeats 10–35 times; in people with Huntington’s disease, the segment repeats 36–120 times or more, causing production of an abnormally long version of the protein. That gets broken into toxic fragments that bind together and accumulate in neurons, disrupting normal function and leading to cell death (1).

Huntington’s disease is incurable and causes a patient’s physical and mental abilities to deteriorate in middle age. Children of HD parents face a 50/50 chance of inheriting the faulty gene. According to the Huntington’s Disease Society of America (HDSA), some 30,000 Americans are symptomatic and more than 200,000 are at risk of inheriting the disease. In about 10% of cases, children or adolescents will be affected by juvenile Huntington’s disease (JHD), which typically progresses more rapidly than adult-onset HD.

Treatment Options: No treatment is yet approved to stop or reverse Huntington’s disease. Some medications (e.g., antipsychotics, antidepressants, and tranquilizers) help control symptoms. And patients who exercise tend to do better than those who do not (1).

HD scientists are exploring the use of experimental gene-editing to edit or delete the HD mutation. Clustered regularly interspaced short palindromic repeats (CRISPR) technology uses a guide RNA and the Cas9 cutting enzyme to identify and delete a gene or to make cuts that render it unreadable (2).

An Emory University team led by Xiao-Jiang Li has found that using CRISPR–Cas9 shows potentially beneficial effects in HD mice. The team injected viruses carrying the guide RNA and Cas9 into the HD-damaged parts of mouse brains. After a few weeks, the CRISPR– Cas9 components had spread and disabled the defective HD gene, diminishing stress on the neurons. After three months, the amount of huntingtin protein clumps built up in brain cells had decreased, and the treated mice improved in movement tests. Even older mice that had developed symptoms improved after treatment (2). Most people with HD have one copy of the mutant gene and one copy of a healthy gene, so there is some concern that the latter could be damaged by such treatment.

Two other groups are working to improve the CRISPR–Cas9 technique. At Massachusetts General Hospital, Jong-Min Lee and colleagues made an allelespecific deletion to edit only the dysfunctional copy of the HTT gene. And at Children’s Hospital of Philadelphia, Beverly Davidson and colleagues have used a similar approach to target only the mutant gene by making smaller cuts with Cas9 (2).

Meanwhile, an ongoing study by Ionis Pharmaceuticals is focused on an antisense oligonucleotide (ASO) Huntington-lowering drug. ASO drugs work by attaching themselves to the messenger ribonucleic acid (mRNA) between a gene and cellular protein-making mechanisms, thus disabling the mRNA from doing its job so that less huntingtin protein is made. Dosages must be carefully determined because this approach lowers both the normal and disease-causing forms of the protein (3).

Organization: “The pace of scientific progress, especially in the area of gene editing, is very exciting for families affected by hereditary diseases like Huntington’s disease, which affects more than 30,000 Americans,” says Louise Vetter (HDSA president and CEO). “Being able to lower the impact of mutant huntingtin in the body and potentially edit it out with technologies like CRISPR–Cas9 would be a huge breakthrough in efforts to improve the lives of everyone affected by HD and ultimately stop the disease.”

HDSA is a nonprofit organization dedicated to improving the lives of everyone affected by Huntington’s disease through treatment, community services, education, advocacy, and research. The organization was founded in 1967 by Marjorie Guthrie, the wife of legendary folk singer Woody Guthrie, who died from HD complications at age 55. Chapters and affiliates support HDSA’s mission by bringing community-based services, awareness, and grassroots fundraising to families affected by HD. HDSA has 41 treatment centers of excellence, 65 social workers, and more than 160 support groups across the United States.

Vetter says, “Today, HD families ask not if there will be a treatment or cure, but when. Our responsibility at HDSA is to ensure that we provide credible and meaningful information regarding the exciting research that is underway so that families have realistic expectations and can gain access to the best care to manage their disease even while the pace of science moves forward.”

UK Regenerative Medicine Thrived in 2017


In its 2017 annual review, the Cell and Gene Therapy Catapult (CGTC) shared an overview of its own work and the United Kingdom’s thriving cell and gene therapy sector. The company operates as an independent center of excellence to advance the growth of the UK regenerative medicine industry by bridging the gap between scientific research and full-scale commercialization. It seeks to establish the country as the go-to place development of living medicines.

In 2017, CGTC acquired Catapult Therapy TCR (Cell Medica’s subsidiary for developing WT1 TCR T-cell therapy). Autolus and Cell Medica became the first companies to occupy space at the CGTC manufacturing center, alongside Fisher BioServices’s CyroHub. Asymptote and CGTC have developed new benchtop thawing devices. The company is sharing expertise and technology with collaborators in the United States, Canada, China, Japan, and South Korea. And it is conducting ongoing research at laboratories in Guy’s Hospital (London, UK).

CEO Keith Thompson says, “We are encouraged to see the global standing of our sector highlighted by agreements in leading advanced-therapy countries such as the United States and Japan, along with highly innovative collaborators in the United Kingdom, from fledgling biotechs to big pharma giants. But there is still much we can do. Our manufacturing center in Stevenage will serve as a vital bridge to help advanced-therapy companies commercialize their treatments.”
