Rotavirus infection of the intestine is a major cause of diarrhoea in infants and children. New research has identified an immune pathway within gut epithelial cells that can detect the virus early and restrict its growth.
Looking beyond what is visible to the naked eye makes the world a much more interesting place.
Scientists in Ireland have linked the gut microbiome with anxiety disorders. The researchers showed that germ-free mice, mice with no gut bacteria, had changes in the part of the brain that controls emotions.
Scientists in the US have recently shown the feasibility of growing intestines in the lab, complete with nerves and muscles.
Gut Health Network student member, Bailey Kennedy, is running the St Clair Vineyard half marathon to raise money for bowel cancer research. Bailey is a PhD student at the University of Otago Christchurch campus, researching immune responses in people with colorectal cancer.
The Kenneth Rainin Foundation is a US-based funding body that supports research into (among other things) Inflammatory Bowel Diseases. Their new video series is Breakthrough Moments, stories of discovery and illumination that provide inspiration to the Kenneth Rainin Foundation’s commitment to taking smart risks in our grantmaking in the Arts, Education and Health.
One effect of weight-loss surgery is a change in food preferences. A new study in rats was recently published and showed that this change is caused by altered nutrient signals in the intestine. These activate the vagus nerve to increase signalling in the brain by the neurotransmitter dopamine.
We will be back updating this site in late January 2017.
A low-fibre diet reduces the number of fibre-eating microbes making the intestine more vulnerable to infection from other microbes.
