Preventing ‘chemo brain’ with antioxidants targeting the spinal fluid
Up to three-quarters of patients receiving cancer chemotherapy suffer from “chemo brain” — a side effect that makes it harder to remember things, maintain attention, and learn new information. When it strikes children, whose brains are still developing, effects are sometimes long lasting, affecting their schoolwork and self-esteem. “One of the most distressing potential side ...

A new view of heart health: Mutations accumulate in the heart starting in childhood
Why do so many people get heart disease when they get older? We know that factors like high blood pressure or high cholesterol contribute to heart disease risk, but they don’t explain all cases. A first-of-its-kind study from Boston Children’s Hospital offers a new lens on heart health. It shows that the cells of our ...

How protected am I from COVID-19? A new test could tell you at home
Say you’re going to a wedding or a concert or are about to leave the country. You’ve been vaccinated against COVID-19, even boosted, but you have an underlying medical condition. You might have a young child who’s received only one vaccine dose. How much protection do you and your family have? Do you need another ... Read More about How protected am I from COVID-19? A new test could tell you at home
Powerful new antibody neutralizes all known coronavirus variants
As the COVID-19 pandemic wears on, newer variants of the SARS-CoV-2 coronavirus have been evolving ways to evade the antibodies we make in response to vaccines or prior infections. As a result, we’ve seen breakthrough cases, antibody treatments that once worked have also become less effective over time. Scientists have been searching for an antibody ...

Weight loss: When scientific paradigms collide
David S. Ludwig, MD, PhD, co-directs the New Balance Foundation Obesity Prevention Center at Boston Children’s Hospital. Because conventional thinking usually rests on years (sometimes centuries) of research, scientists are naturally skeptical of radical new ideas. But occasionally, problems with normal science arise, such as a persistent failure to solve important puzzles and anomalies that can’t be ...

Making ready-made CAR T cells for cancer immunotherapy
In CAR T-cell immunotherapy, T cells from a patient’s own blood are engineered to carry so-called chimeric antigen receptors (CAR) that enable the T cells to attack and kill tumor cells. While CAR-T therapy is a powerful approach for certain leukemias and lymphomas, it’s not available for many patients who need it. It can be ...

A new vaccine formulation could finally protect babies against RSV
Though often mild, respiratory syncytial virus (RSV) infection can cause babies to be hospitalized with bronchiolitis or pneumonia. Globally, it is the leading cause of death in children under 5. Several vaccines against RSV are being tested in adults. But there has been no progress on an RSV vaccine for children since 1966 — the ...

A potential danger of CRISPR gene editing — and why base editing may be safer
Gene therapy using CRISPR/Cas9 gene editing is currently in clinical trials around the world for a variety of diseases, including various cancers, blood disorders, and metabolic disorders. It works by making cuts in DNA — both strands of the double helix — to insert or remove genes. But CRISPR carries a potential, previously undiscovered danger, ...

New work transforms our knowledge of how blood is formed
The origins of our blood may not be quite what we thought. In groundbreaking research, scientists in the Stem Cell Program at Boston Children’s Hospital used cellular “barcoding” techniques in mice to track the development of blood in real time — and found that blood cells originate not from one type of mother cell, but ...

Exploiting a vulnerability in an aggressive leukemia
Survival has improved greatly in children with acute lymphocytic leukemia (ALL). But a certain form of ALL that occurs mostly in babies is still very lethal, with a survival rate below 50 percent: B-cell acute lymphoblastic leukemia with rearrangements of the mixed lineage leukemia gene, or MLL B-ALL. “Something about the biology of this type ...
