Partnering diet and intestinal microbes to protect against GI disease
Despite being an everyday necessity, nutrition is something of a black box. We know that many plant-based foods are good for us, but we don’t always know why. Our intestinal microbiome, which helps break down these foods once we consume them, is another black box. What role do our gut bacteria play? Seth Rakoff-Nahoum, MD, ...

A better treatment for endometriosis could lie in migraine medications
Endometriosis is a common, mysterious, often painful condition in which tissue similar to the uterine lining grows outside the uterus, forming lesions in locations such as the fallopian tubes, ovaries, and pelvis. These lesions can cause severe pain during periods, heavy menstrual bleeding, pelvic or abdominal pain, and sometimes painful bowel movements and urination. Existing ...

Modeling urinary tract disorders on a chip: Zohreh Izadifar
When a new tissue sample arrives from the Department of Urology, the Boston Children’s Hospital lab of Zohreh Izadifar, PhD springs into action. The tissue, from a child with urinary tract pathology, is whisked into the tissue culture room. Under a hood, lab members Dasvit Shetty, PhD, and Gretchen Carpenter, MSc, carefully isolate the cells ... Read More about Modeling urinary tract disorders on a chip: Zohreh Izadifar
A surprising link between Crohn’s disease and the Epstein-Barr virus
Crohn’s disease, a debilitating inflammatory bowel disease, has many known contributing factors, including bacterial changes in the microbiome that foster an inflammatory environment. Now, for the first time, Crohn’s disease been tied to a virus — specifically, Epstein-Barr virus (EBV), best known for causing infectious mononucleosis (mono). Researchers had already observed increased levels of EBV ... Read More about A surprising link between Crohn’s disease and the Epstein-Barr virus
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
Bringing order to disorder: Jhullian Alston, PhD
Proteins typically fold into orderly, predictable three-dimensional structures that dictate how they will interact with other molecules. Jhulian Alston, PhD, is drawn to intrinsically disordered proteins, whose key feature is a lack of structure. They are difficult to study and far less explored. “They’re floppy, they don’t have specific folds, they can’t slot into each ... Read More about Bringing order to disorder: Jhullian Alston, PhD
Status epilepticus: What’s changed, what to know, and a global perspective
Status epilepticus, or a prolonged seizure lasting more than five minutes, is a rare complication of epilepsy and a medical emergency that can occur even in people without a diagnosis of epilepsy. If not treated quickly, it can cause brain damage, lifelong complications, and even death. “A prolonged seizure is a race against time to ...

Phenylketonuria: Giving treatment a second chance
Phenylketonuria (PKU) was once a common cause of intellectual disability. Children born with this metabolic condition lack phenylalanine hydroxylase (PAH), the enzyme needed to break down the amino acid phenylalanine (phe). Instead, phe builds up to levels harmful to the brain. PKU was the original condition tested for when newborn screening was piloted in Massachusetts ...
