Catching platelets with NETs: Neutrophils and deep vein thrombosis
Sea cucumbers have an unusual way of defending themselves. When threatened, they ensnare their foes with sticky threads. Some even expel their own internal organs to repel attackers. Immune system cells called neutrophils sometimes do much the same: When confronted with bacteria, they unravel and shoot out their chromatin—the tightly wound mix of DNA and proteins that ...

Restoring muscle function in a rare, devastating disease: Part 1
Part 1 of a two-part series. (Read part 2.) Sixth-grader William Ward cruises the hallways at school with a thumb-driven power chair and participates in class with the help of a DynaVox speech device. Although born with a rare, muscle-weakening disease called X-linked myotubular myopathy, or MTM, leaving him virtually immobile, he hasn’t given up. Neither has Alan Beggs, ...

This post may contain peanuts: Two-pronged treatment may ease severe allergies
Tripp Underwood contributed to this post. Families with peanut-allergic children live in fear that their child will ingest peanuts—even minute amounts—accidentally. Now, a small pilot study published in the Journal of Allergy and Clinical Immunology offers hope for peanut allergy. In the year-long study, immunologist Dale Umetsu, MD, PhD, and colleagues in the Division of Allergy and Immunology at ...

Inherited autism mutations found via genomic sequencing in Mideast families
Autism clearly runs in some families, yet few inherited genetic causes have been found. A major reason is that these causes are so varied that it’s hard to find enough people with a given mutation to establish a clear pattern. Now, three large Middle Eastern families with autism spectrum disorders (ASDs) have led the way ... Read More about Inherited autism mutations found via genomic sequencing in Mideast families

Building a body, one organ chip at a time
They don’t look like much sitting in your hand. A few pieces of clear plastic, each smaller than an Altoids tin, with channels visible inside and holes for plugging tubing into them. But fill them with cells and treat those cells the right way, and they turn into something amazing: tiny hearts, lungs, guts, kidneys. ... Read More about Building a body, one organ chip at a time

Not the congenital heart defects we so commonly see in babies coming to Boston Children’s Hospital, but the kind of disease you ...

Not all brain tumors are made the same, and that’s important
When you look at an apple, no matter what variety, on the surface you can be pretty sure it’s actually an apple. From there, you can make lots of assumptions about it, like how it will taste when you bite into it and what will happen if you plant the seeds in your yard. With ...
