Crohn’s disease is an inflammatory bowel disease linked to an imbalance in the gut microbiome. Now, researchers at McMaster University have found in mice a way to target and 'turn off' only the bad gut bacteria using specially trained, precision viruses. This breakthrough paves the way for treatments tailored to each patient.
Scientists discover that a gut microbiota molecule causes atherosclerosis
7 Jan 2026by Cristina Sáez
A new study reveals that a molecule produced by gut bacteria can trigger atherosclerosis, shedding light on why some healthy individuals develop cardiovascular disease.
Imidazole propionate: a novel driver of atherosclerosis and biomarker of subclinical disease
4 Dec 2025by Andreu Prados
Cardiovascular diseases remain one of the most pressing public health concerns, demanding innovative research to identify novel causes. A recent Nature study reported that imidazole propionate made by gut bacteria contributes to atherosclerosis development, supporting its potential role as a biomarker of subclinical disease.
A new stool biomarker for multiple sclerosis: gut bacteria’s role in disease progression
13 May 2025by Manon Oliero
New research suggests that changes in the ratio between two common gut bacteria could be associated with symptom severity in people with multiple sclerosis. While more studies are needed, the findings point to a potential microbial marker for monitoring the disease.
We continue our series on the gut axis, this time focusing on the gut-skin connection. You might have noticed it yourself—how a heavy, sugary meal can lead to breakouts the next day, or how certain food allergies can trigger rashes. This is the gut-skin axis at work, demonstrating an association between the health of our gut and the condition of our skin, and vice versa.
You are probably familiar with the gut-brain connection. But did you know that your gut and lungs are in constant conversation? Scientists call this connection the gut-lung axis. Both the gut and lungs are mucosal organs—while the gut absorbs nutrients from food, the lungs absorb gases like oxygen from the air.
Dietary fibers, known to regulate intestinal inflammation and gut barrier functions, have been avoided by patients with inflammatory bowel diseases (IBD) to avoid flare-ups. However, recent findings suggest that if fiber type, patient immunological condition, and the fermentative ability of the gut microbiota are taken into account, they could be beneficial and prevent relapses.
Restricting dietary fiber is a common advice for people living with inflammatory bowel disease. New research shows that not all fibers work the same and their impact on intestinal inflammation and gut barrier function depends on the type of fiber, individual immune status and the fermentative capacity of their gut microbes.

Allergic children present different bacterial strains that promote inflammation
21 Apr 2022by Manon Oliero
Rural living, vaginal delivery, pet ownership, eating a wide variety of foods, low antibiotic use, and breast milk microbiota can prevent your children from developing a respiratory or food allergy. But what if differences in the gut microbiota could predict which children will grow out of their allergies?
