Missed signals? A new way we vary from each other biologically
Genetics has made huge strides over the past 20 years, from the sequencing of the human genome to a growing understanding of factors that turn genes on and off, namely transcription factors and the DNA “enhancer” sequences they bind to. New research from Boston Children’s Hospital introduces another previously unknown layer of human genetics. It ... Read More about Missed signals? A new way we vary from each other biologically
Rising global temperatures tied to rising antibiotic resistance
A new data analysis suggests that two rising public health threats — climate change and antibiotic resistance — are related. The study, spanning 2000 to 2016, doesn’t establish cause and effect. But its findings, in the journal Eurosurveillance, suggest that rising global temperatures could be helping to fuel increases in antibiotic-resistant bacteria. Key takeaway Countries ...

Tau protein changes correlate with Alzheimer’s disease dementia stage
Research into Alzheimer’s disease has long focused on understanding the role of two key proteins, beta amyloid and the tau protein. Found in tangles in patients’ brain tissue, a pathological form of the tau protein contributes to propagating the disease in the brain. Key takeaways A pathological form of the tau protein contributes to the ... Read More about Tau protein changes correlate with Alzheimer’s disease dementia stage
Precision chemo-immunotherapy for pancreatic cancer?
Pancreatic cancer is highly lethal and in great need of better treatments. Only about 10 percent of patients remain alive five years after diagnosis. In a new study, researchers in the lab of Marsha Moses, PhD, at Boston Children’s Hospital offer a glimmer of hope. Key takeaway An antibody-drug combination effectively targeted, penetrated, and shrank ... Read More about Precision chemo-immunotherapy for pancreatic cancer?
Why do some children exposed to the coronavirus go on to develop MIS-C?
Most children exposed to the SARS-CoV-2 coronavirus have few or no symptoms. But a small number become sick enough to go to the hospital. And a tiny handful develop a severe inflammatory illness called multisystem inflammatory syndrome (MIS-C), often weeks after initial exposure to the virus. Why? A team at Boston Children’s Hospital is using ... Read More about Why do some children exposed to the coronavirus go on to develop MIS-C?
Chromatin regulation enables generation of diverse antibodies
We need a variety of antibody types to help fight off invading foreign pathogens and our genome is exquisitely tuned to produce them to meet emerging needs. A new study finds that not just our DNA, but its configuration and packaging, help us generate diverse antibodies. Key takeaways Chromatin loop extrusion leads to creation of ...

Study: Even strict gluten-free diets may not completely prevent gluten exposure
Even a strict gluten-free (GF) diet may not help people with celiac disease completely avoid gluten. That’s the finding of a recent study by Jocelyn Silvester, MD, PhD, and her colleagues at the University of Manitoba, Beth Israel Deaconess Medical Center, and the University of Seville. They sought to determine whether GF diets still contain ... Read More about Study: Even strict gluten-free diets may not completely prevent gluten exposure
New strategies for restoring myelin on damaged nerve cells
Key takeaways Myelin is an essential fatty substance coating surrounding nerve axons. After injury, regenerated nerve axons usually fail to remyelinate, inhibiting nerve cell communication. A combination treatment led to remyelination in about 60 percent of regenerated axons. This research may have implications in other diseases associated with myelin loss, like multiple sclerosis. Loss of ... Read More about New strategies for restoring myelin on damaged nerve cells
COVID-19 virus levels in children: Differences between asymptomatic vs. symptomatic kids
A new study finds that most asymptomatic children who tested positive for COVID-19 had lower levels of the virus compared to symptomatic children. While it is the first large and comprehensive investigation of its kind in asymptomatic children, several important questions remain unanswered. Nira Pollock “Our study did show that asymptomatic children had lower viral ... Read More about COVID-19 virus levels in children: Differences between asymptomatic vs. symptomatic kids
A COVID-19 DNA nanoswitch: A new kind of test for a new kind of virus
When the COVID-19 pandemic shut down research laboratories across the country, several labs at Boston Children’s Hospital geared up, including that of Wesley Wong, PhD. He and his team responded to the threat by developing a new, easy diagnostic test for COVID-19. Wesley Wong “Our technology, a DNA nanoswitch, is a new way of probing ...
