How our neutrophils might sabotage wound healing in diabetes
When you get a cut or a scrape, your body jumps into action, mobilizing a complicated array of cells and factors to stem bleeding, keep the wound bacteria-free and launch the healing process. For most of us, that process is complete in a couple of weeks. But for many people with type 1 and type ... Read More about How our neutrophils might sabotage wound healing in diabetes
Fruit flies’ love lives could clarify brain cells’ role in motivation
If you have children present, you might want to click out of this post. But if you want to understand motivation, you’ll want to know about the sexual behavior of fruit flies. In the brain, motivational states are nature’s way of matching our behaviors to our needs and priorities. But motivation can go awry, and ...

New Human Neuron Core to analyze ‘disease in a dish’
Last week was a good week for neuroscience. Boston Children’s Hospital received nearly $2.2 million from the Massachusetts Life Sciences Center (MLSC) to create a Human Neuron Core. The facility will allow researchers at Boston Children’s and beyond to study neurodevelopmental, psychiatric and neurological disorders directly in living, functioning neurons made from patients with these ...

A simpler way to measure complex biochemical interactions
Life teems with interactions. Proteins bind. Bonds form between atoms, and break. Enzymes cut. Drugs attach to cell receptors. DNA hybridizes. Those interactions make the processes of life work, and capturing them has led to many medical advances. “Determining which molecules interact, and measuring the strength of these interactions is fundamental for many areas of ...

Frozen poop pill offers a less invasive treatment option for emerging infectious disease
The fecal microbiota transplantation (FMT) movement is catching the attention of scientists, researchers and the media nationwide. Currently, fecal transplantation delivers pre-screened, healthy human donor stool to a patient via colonoscopy or by nasogastric tube. It’s prescribed as an effective alternative to long-term antibiotic use in treating debilitating infectious diseases such as Clostridium difficile, also known ...

Genome editing: A CRISPR way to correct disease
Technology sometimes unfolds at a slow, measured pace and sometimes at lightning speed. Right now, we are witnessing what is arguably one of the fastest moving fields in biomedical science: a form of genome editing aptly known as CRISPR. CRISPR allows researchers to make very precise—some would say crisp—changes to the genomes of human cells ... Read More about Genome editing: A CRISPR way to correct disease
Stem cell medicine gets a “roadmap” and a quality assurance tool
If you’ve lost your way on the Boston subway, you need only consult a map to find the best route to your destination. Now stem cell engineers have a similar map to guide the making of cells and tissues for disease modeling, drug testing and regenerative medicine. It’s a computer algorithm known as CellNet. As ...

Gene therapy gets in the ring with another disease
Seeing that his mother, Kadriye, wasn’t looking, Emir Seyrek got an impish grin on his face, the kind only a two-year-old can have. He quietly dumped his bowl of dry cereal out on his bed and, with another quick look towards his mother, proceeded to pulverize the flakes to dust with his toy truck. The ...

‘Heart on a chip’ suggests a surprising treatment for a rare genetic disease
It was the variability that intrigued pediatric cardiologist William Pu, MD, about his patient with heart failure. The boy suffered from a rare genetic mitochondrial disorder called Barth syndrome. While he ultimately needed a heart transplant, his heart function seemed to vary day-to-day, consistent with reports in the medical literature. “Often patients present in infancy with severe ...

Autism clinical trials are ripe for improvement
Walter Kaufmann, MD, is co-director of the Fragile X Syndrome Program and a member of the department of Neurology at Boston Children’s Hospital. He was site principal investigator for three arbaclofen trials sponsored by Seaside Therapeutics and currently advises the company on data analyses. This post is second in a two-part series on clinical trials in ... Read More about Autism clinical trials are ripe for improvement
