Research has shown that the gut microbiome plays a very important role in our health as they carry out their duties that are key to survival.
These microbes help by controlling our appetite, digestion and in benefiting our immune system and many other aspects of health. An imbalance of unhealthy and healthy microbes in the intestines may contribute to weight gain, high blood sugar, high cholesterol and other disorders.
A team of researchers at the Institut d’Investigacions Biomèdiques August Pi i Sunyer (IDIBAPS) in Barcelona and the University of Calgary in Canada has discovered a novel mechanism through which gut microbiota regulates the organism’s immune response, in particular the immune response involved in autoimmune diseases. Their findings have been published in Cell,
“We have observed that a protein expressed by gut microbiota bacteria, called Bacteroides, acts to prevent IBD by recruiting white blood cells to kill an immune system cell that is in charge of orchestrating IBD,” says Kathy McCoy, from the Cumming School of Medicine at the University of Calgary. “We believe this mechanism is probably involved in preventing a lot of people from developing IBD,” she adds.
