Robert Moir, 58, Dies; His Research Changed Views on Alzheimer’s Robert Moir, 58, Dies; His Research Changed Views on Alzheimer’s

Robert D.

Dr. Moir, who grew up on a farm in Donnybrook, a small town in Western Australia, had a track record for confounding expectations. He did not learn to read or write until he was nearly 12; Ms. Alperen said he told her that the teacher at his one-room schoolhouse was “a demented nun.” Yet, she said, he also knew from age 7 that he wanted to be a scientist.

He succeeded in becoming a researcher who was modest and careful, said his Ph.D. adviser, Dr. Colin Masters, a neuropathologist at the University of Melbourne. So Dr. Masters was surprised when Dr. Moir began publishing papers proposing an iconoclastic rethinking of the pathology of Alzheimer’s disease.

Dr. Moir’s hypothesis “was and is a really novel and controversial idea that he alone developed,” Dr. Masters said. “I never expected this to come from this quiet achiever.” Dr. Moir’s hypothesis “was and is a really novel and controversial idea that he alone developed,” Dr. Masters said.

Dr. Moir’s theory involved the protein beta amyloid, which forms plaques in the brains of Alzheimer’s patients.Dr. Moir’s theory involved the protein beta amyloid, which forms plaques in the brains of Alzheimer’s patients.
Conventional wisdom held that beta amyloid accumulation was a central part of the disease, and that clearing the brain of beta amyloid would be a good thing for patients.Conventional wisdom held that beta amyloid accumulation was a central part of the disease, and that clearing the brain of beta amyloid would be a good thing for patients.
Dr. Moir proposed instead that beta amyloid is there for a reason: It is the way the brain defends itself against infections. Beta amyloid, he said, forms a sticky web that can trap microbes. The problem is that sometimes the brain goes overboard producing it, and when that happens the brain is damaged.Dr. Moir proposed instead that beta amyloid is there for a reason: It is the way the brain defends itself against infections.

The implication is that treatments designed to clear the brain of amyloid could be detrimental. The goal would be to remove some of the sticky substance, but not all of it.The implication is that treatments designed to clear the brain of amyloid could be detrimental.

The idea, which Dr. Moir first proposed 12 years ago, was met with skepticism. But he kept at it, producing a string of papers with findings that supported the hypothesis. Increasingly, some of the doubters have been won over, said Rudolph Tanzi, a close friend and fellow Alzheimer’s researcher at Harvard.The idea, which Dr. Moir first proposed 12 years ago, was met with skepticism.

Dr. Moir’s unconventional ideas made it difficult for him to get federal grants. Nearly every time he submitted a grant proposal to the National Institutes of Health, Dr. Tanzi said in a telephone interview, two out of three reviewers would be enthusiastic, while a third would simply not believe it. The proposal would not be funded. Dr. Moir’s unconventional ideas made it difficult for him to get federal grants.

“He’d make a joke about it,” Dr. Tanzi said. “He never got angry. I never saw Rob angry in my life. He’d say, ‘What do we have to do next?’ He was always upbeat, always optimistic.”“He’d make a joke about it,” Dr. Tanzi said. “He never got angry. I never saw Rob angry in my life.

For example, Dr. Moir and Dr. Tanzi found that people naturally make antibodies to specific forms of amyloid. These antibodies protect the brain from Alzheimer’s but do not wipe out amyloid completely. The more antibodies a person makes, the greater the protection against Alzheimer’s.For example, Dr. Moir and Dr. Tanzi found that people naturally make antibodies to specific forms of amyloid.

That finding, Dr. Tanzi said, inspired the development of an experimental drug, made by Biogen, that the company says is helping to treat some people with Alzheimer’s disease. Biogen plans to file for approval from the Food and Drug Administration.

Once he learned to read, Ms. Alperen said, he never stopped — he read science fiction, the British magazine New Scientist and even PubMed, the federal database of scientific publications.Once he learned to read, Ms. Alperen said, he never stopped — he read science fiction, the British magazine New Scientist and even PubMed, the federal database of scientific publications.

He shared that love with his family, on frequent hikes and on trips with his young children to look for rocks, insects and fossils. He also played Australian rules football, which has elements of rugby as well as American football, and helped form the Boston Demons Australian Rules Football Team in 1997, his wife said.

In addition to his wife, with whom he lived in Sharon, Mass., Dr. Moir’s survivors include three children, Alexander, Maxwell and Holly Moir; a brother, Andrew; and a sister, Catherine Moir. His marriage to Elena Vaillancourt ended in divorce.In addition to his wife, with whom he lived in Sharon, Mass., Dr. Moir’s survivors include three children, Alexander, Maxwell and Holly Moir; a brother, Andrew; and a sister, Catherine Moir.
