Could peripheral neuropathy be stopped before it starts?
An increase in high-fat, high-fructose foods in people’s diets has contributed to a dramatic increase in type 2 diabetes. This, in turn, has led to an increase in peripheral neuropathy — nerve damage, typically in the hands and feet — that causes weakness, loss of sensation and, in some, a stabbing, burning, or tingling pain. ...

Modifying macrophages in the lung could head off pulmonary hypertension
In the 1980s, when Stella Kourembanas, MD, began her career in neonatology, she cared for newborns with pulmonary hypertension, a disease that results in abnormally high blood pressure in the lung arteries and can lead to heart failure. Since then, treatments like inhaled nitric oxide, new vasodilators, new modalities of mechanical ventilation, and extracorporeal membrane ...

A new tool could exponentially expand our understanding of bacteria
How do bacteria — harmless ones living in our bodies, or those that cause disease — organize their activities? A new study, combining powerful genomic-scale microscopy with a technical innovation, captured which genes bacteria turn on in different situations and in different spatial environments. The technology, described January 23 in Science, promises to take the ... Read More about A new tool could exponentially expand our understanding of bacteria
Could we cure or prevent food allergy by targeting an intestinal protein?
When is food simply nourishing and enjoyable, and when does it provoke an allergic reaction? The answer appears to lie in the balance of microbes that live in our intestine — and a specific protein secreted by intestinal goblet cells that influences that balance. Excess amounts of this protein, RELMß, change the profile of intestinal ... Read More about Could we cure or prevent food allergy by targeting an intestinal protein?
Mapping cells to create targeted treatments for interstitial lung disease
John Kennedy, MD, MSc, remembers the relative simplicity of his first genetic mapping project. In a Harvard Medical School lab, he helped map a gene for the neurological disease mucolipidosis type IV in less than a year. “I was fresh out of college. I thought with the global momentum of the Human Genome Project, we were going to ... Read More about Mapping cells to create targeted treatments for interstitial lung disease
Blood across our lifetimes: An age-specific ‘atlas’ tells a dynamic story
The stem cells that form our blood, also known as hematopoietic stem cells (HSCs), are with us throughout our lives. A new study reveals how HSCs ramp up and pivot their activities depending on the body’s needs at the time, from before we’re born until old age. Researchers at Dana-Farber/Boston Children’s Cancer and Blood Disorders ... Read More about Blood across our lifetimes: An age-specific ‘atlas’ tells a dynamic story
