A deeper understanding of inflammatory pain could reveal new solutions
Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen are the main go-to for inflammatory pain caused by wounds, infection, sunburn, arthritis, and other triggers. NSAIDs work pretty well, but chronic use can cause side effects, and they aren’t equally effective for all sources of pain. Could we identify a more effective, safer analgesic that doesn’t involve ... Read More about A deeper understanding of inflammatory pain could reveal new solutions
Mitochondrial transfer restores heart muscle — but how?
Transferring mitochondria from a patient’s healthy skeletal muscle to damaged, ischemic heart tissue has been shown to restore heart muscle, increase energy production, and improve ventricular function. After pioneering preclinical work by James McCully, PhD, at Boston Children’s Hospital about a decade ago, cardiac surgeons led by Sitaram Emani, MD, have been testing it as ...

Study suggests hypoxia overexpression causes pericytes to contribute to pulmonary hypertension
Pericytes, the multifunctional cells that work within the walls of capillaries, have been a subject of focus in the study of vascular development, cerebral blood flow, cancer, and neurodevelopment diseases. But pericytes hadn’t been truly studied for their potential role in pulmonary arterial hypertension (PAH) until they landed under the microscopes of Boston Children’s researchers. They recently ...

Mending injured hearts: Lessons from newborns?
When the heart is injured, as in a myocardial infarction, the damaged heart muscle cannot regenerate — instead, scar tissue forms. Cardiomyocytes, the heart muscle cells that generate contractile force, are lost for good. Yet, in mouse models, the hearts of newborns regenerate readily after injury. How are newborn hearts able to recover? What are ... Read More about Mending injured hearts: Lessons from newborns?
A journey through the intestine during colitis, cell by cell
Inflammatory bowel disease (IBD), causing devastating abdominal pain, persistent diarrhea, and rectal bleeding, is hard to control with current treatments. Children often experience malnutrition and impaired growth. To get a better handle on IBD, researchers at Boston Children’s Hospital and Brigham and Women’s Hospital decided to eavesdrop on happenings in the colon. In the first ...

BRD7 research points to alternative insulin signaling pathway
Bromodomain-containing protein 7 (BRD7) was initially identified as a tumor suppressor, but further research has shown it has a broader role in other cellular processes, including the remodeling of chromosomes and cell cycle progression. Now, Boston Children’s Division of Endocrinology researchers have discovered another purpose for BRD7: It seems to be involved in an alternative insulin signaling ...

Genetic variants are found in two types of strabismus, sparking hope for future treatment
Determining how genetics contribute to common forms of strabismus has been a challenge for researchers. Small discoveries are considered meaningful progress. Boston Children’s researchers believe they’ve helped move the needle. They discovered that two types of strabismus — esotropia and exotropia — may have shared genetic risk factors. Duplications on the second, fourth, and tenth chromosomes that ... Read More about Genetic variants are found in two types of strabismus, sparking hope for future treatment
Exploring brain operations: Making decisions, snapping to attention, and forming memories
How do our brains snap to attention and orient us to the outside world — like when we’re sound asleep and the smoke alarm goes off? And when different choices confront us, how does our brain make decisions? Two groups of researchers at Boston Children’s explored these all-important brain operations. The first study, published February ... Read More about Exploring brain operations: Making decisions, snapping to attention, and forming memories
In the genetics of congenital heart disease, noncoding DNA fills in some blanks
Researchers have been chipping away at the genetic causes of congenital heart disease (CHD) for a couple of decades. About 45 percent of cases of CHD have an identifiable cause, including chromosomal abnormalities, genetic variants affecting protein-coding genes, and environmental factors. What about the rest of the cases of CHD? Noncoding DNA elements have long ... Read More about In the genetics of congenital heart disease, noncoding DNA fills in some blanks
Microvillus inclusion disease: From organoids to new treatments
Microvillus inclusion disease (MVID) is a rare type of congenital enteropathy in infants that causes devastating diarrhea and an inability to absorb food. Infants can lose liters of fluid a day, become severely dehydrated, and stop growing. There is no specific treatment. “Until about 10 years ago, 50 percent of kids with MVID would die ...
