While researching a rare blood disorder called Diamond-Blackfan anemia, scientists stumbled upon an even rarer anemia caused by a previously-unknown genetic mutation. During their investigation, the team of scientists — from the Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, the Broad Institute of Harvard and MIT and Yale University — had the relatively unusual opportunity to develop an “on-the-fly” therapy.
As they analyzed the genes of one boy who had died from the newly-discovered blood disorder, the team’s findings allowed them to help save the life of his infant sister, who was also born with the same genetic mutation. The results were recently reported in Cell.
“We had a unique opportunity here to do research, and turn it back to a patient right away,” says Vijay Sankaran, MD, PhD, the paper’s co-corresponding author and a principal investigator at the Dana-Farber/Boston Children’s Cancer and Blood Disorders Center. “It’s incredibly rewarding to be able to bring research full circle to impact a patient’s life.” …
Autoimmune disease is usually treated using general immunosuppressants. But this non-targeted therapy leaves the body more susceptible to infection and other life-threatening diseases.
Now, scientists at Boston Children’s Hospital, the Massachusetts Institute of Technology (MIT) and the Whitehead Institute for Biomedical Research think they may have found a targeted way to protect the body from autoimmune disease. Their approach, published in Proceedings of the National Academy of Sciences, uses transfusions of engineered red blood cells to re-train the immune system. Early experiments in mice have already shown that the approach can prevent — and even reverse — clinical signs of two autoimmune diseases: a multiple-sclerosis (MS)-like condition and Type 1 diabetes. …
Your doctor has a lot of tools to detect, diagnose and monitor disease: x-rays, MRIs, angiography, blood tests, biopsies…the list goes on.
What would be great would be the ability to test for disease in a way where there’s no or low pain (not invasive) and lots of gain (actionable data about the disease process itself, its progression and the success of treatment).
