The enemy within: Gut bacteria drive autoimmune disease

Bacteria found in the small intestines of mice and humans can travel to other organs and trigger an autoimmune response, according to a new Yale study. The researchers also found that the autoimmune reaction can be suppressed with an antibiotic or vaccine designed to target the bacteria, they said. The findings, published in Science, suggest promising new approaches for treating ...

True to type: From human biopsy to complex gut physiology on a chip

The small intestine is the main site where we digest and absorb nutrients and minerals from food, and it is also a place where many intestinal infections occur and digestive and inflammatory disorders manifest themselves. To better understand the intestine in its normal and pathological states, researchers have created “organoids” by isolating intestinal stem cells from human biopsy samples. These ...

Gut microbes protect against sepsis: Mouse study

Sepsis occurs when the body’s response to the spread of bacteria or toxins to the bloodstream damages tissues and organs. The fight against sepsis could get a helping hand from a surprising source: gut bacteria. Researchers reporting February 22 in the journal Cell Host & Microbe found that giving mice particular microbes increased blood levels of immunoglobulin A (IgA) antibodies, ...
