A promising target for ALS and other neurodegenerative disorders: Curbing inflammation
When cells recognize a danger, such as an infection, they activate the innate immune system. Sentinel molecules sound an alarm, recruiting immune cells to take down the threat. In 2016, Judy Lieberman, MD, PhD and her colleagues at Boston Children’s Hospital showed that a protein called gasdermin D initiates a final, decisive step: pyroptosis, a ...

Why do so many dementia treatments fail? Questioning mouse models of tau accumulation
To date, the search for effective treatments for dementia has yielded only disappointments. Many recent drug candidates target the tau protein, which aggregates and forms tangles in patients’ brain tissue and is involved in 75 percent of all dementias. While tau-targeting drugs have looked promising in mouse models, they’ve failed in clinical trials. A recent ... Read More about Why do so many dementia treatments fail?

How a leukemia hijacks the genes needed by blood stem cells
As a child, Lynn Aureli didn’t know that a particular genetic change contributed to her acute myeloid leukemia (AML) — an alteration that eventually would help explain the cancer’s lack of response to chemotherapy. Nor was she aware that her cancer had hijacked the genetic mechanism for maintaining the stem cells that form blood, like ...

Obesity is increasing people’s risk of cancer. Why?
Obesity is now a global epidemic, and it is increasing people’s risk for cancer. The National Cancer Institute lists more than a dozen cancers that are associated with overweight and obesity. But how obesity increases cancer risk hasn’t been clear. The lab of Marsha A. Moses, PhD, at Boston Children’s Hospital, now draws a direct ...

Genetic sequencing may open doors for newborns with hypotonia
When a baby is born with low muscle tone (hypotonia), the future is hard to predict, and families have a lot of questions. How should neonatologists care for these infants? Findings from a recent review could help provide some answers, guide appropriate interventions, and in some cases open the way to custom treatments. Diagnosing a ...

New insight into dietary approaches for epilepsy
Fasting has been believed since ancient times to curb seizures in epilepsy, and small patient studies in the early 1900s have revived the idea. But the reasons have remained mysterious. New research from Boston Children’s helps explain how fasting affects the brain at the molecular level. The findings could lead the way to new approaches ...

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 ...
