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 ...

As COVID-19 fuels opioid deaths, researchers look to create an anti-opioid vaccine
A project that began one year ago at Boston Children’s Hospital to develop an anti-opioid vaccine is starting to bear its first fruits. A team of addiction experts and vaccine developers across the Boston Children’s research community were recently awarded a $25 million research contract from the NIH’s Helping to End Addiction Long-term Initiative, or NIH ...

Too many blood cells: Probing a blood cancer’s genetic origins
At age 7, Meredith Shah began having debilitating migraine headaches. “I would have trouble seeing and shapes were blurry,” she recalls. “It was really painful.” Over time, the frequency and intensity of the headaches escalated. Her parents, Heidi and Nil, sought the help of multiple specialists. But they received few answers, other than an indication ...

The tiny choroid plexus protects the prenatal brain — but may also pass on inflammation from the mother
Floating in fluid deep in the brain are small, little-understood fronds of tissue. Two new studies reveal that these miniature organs are a hotbed of immune system activity. This activity may protect the developing brain from infections and other insults — but may also contribute to neurodevelopmental disorders like autism. Key takeaway This pioneering work ...

Scar-free healing after spinal cord injury relies on specialized cells
Key takeaways Scar tissue prevents nerves from communicating with each other. Microglia cells in the central nervous system help prevent scar tissue formation after spinal cord injuries in newborn mice. Transplanted newborn microglia cells drastically reduced scar formation in adult mice with spinal cord injury, opening the door to new treatment possibilities. One of the ...

Two recent innovations in aerodigestive care
Feeding disorders are extremely common in pediatrics and are a source of significant stress for families. Because many complex feeding disorders lack treatment options, children tend to receive nutrition by feeding tubes as a result. The Aerodigestive Center at Boston Children’s Hospital has been at the forefront of developing novel therapies for feeding disorders. Two ...
