New research NETs a fresh angle for treating severe inflammation
As we’ve seen during the COVID-19 pandemic, serious infections sometimes trigger an excessive inflammatory reaction that does as much harm — or more — than the infection itself. New research at Boston Children’s Hospital and Brigham and Women’s Hospital suggests a potential way to block this hyperinflammation response by repurposing or modifying an existing drug. ...

Finding new targets for acute myeloid leukemia in children
Acute myeloid leukemia (AML) is the second most common leukemia diagnosed in children. It is hard to treat and can be fatal in some cases. While there have been some recent successes with genetically targeted therapies for adults, AML has different genetic features in children, and care has been slow to advance. “The state of ...

‘Human accelerated regions’: How they make our brains uniquely human
Starting when humans diverged from chimpanzees some 5 to 6 million years ago, we’ve evolved in our uniquely human fashion thanks to changes in our genome. And certain parts of the human genome, known as human accelerated regions or HARs, have evolved especially rapidly. Intriguing new work led by Christopher Walsh, MD, PhD, of Boston ... Read More
Unpacking the body’s interferon response to COVID-19
Interferons are potent natural antivirals, rallying other parts of the immune system to defend against viruses. Some clinical trials have tested interferons as a treatment for COVID-19, but results have been mixed. And the science has been unclear about whether interferons are helpful or harmful. Key takeawayAn early, protective interferon response in the upper respiratory ... Read More
RNA-modifying protein offers a possible lead for treating aggressive cancers
A protein that modifies RNAs, called METTL1, could be a target for treating some aggressive, difficult-to-treat cancers, suggests new research in Molecular Cell. The study provides evidence that blocking METTL1 curbs cancer cells’ ability to grow, selectively killing them, and the researchers believe it could be targeted with drugs. METTL1 and related proteins had previously ... Read More
Why do some people get severe COVID-19? The nose may know
The body’s first encounter with SARS-CoV-2, the virus behind COVID-19, happens in the nose and throat, or nasopharynx. A new study in the journal Cell suggests that the first responses in this battleground help determine who will develop severe disease and who will get through with mild or no illness. Building on work published last ... Read More
