(Health News) When you first hear the word “bacteria,” your reaction might be one of disgust. The word brings to mind sickness and gross images of bacteria, but we can also benefit from bacteria — in the gut microbiome, says Dr. Pere Santamaria.

Bacteria Blue - Autoimmune disease and gut health: New study reveals how your microbiome regulates inflammation

A microbiome is a collection of microbes or microorganisms living in an environment and this results in a “mini-ecosystem.” In humans, a microbiome is formed by “communities of symbiotic, commensal and pathogenic bacteria.” The human microbiome is also home to fungi and viruses.

According to Santamaria, “The bacteria we have in our gut actually have many beneficial functions. They help in our digestion, prevent infection by pathogens and educate our immune system on what to fight.” In a recent study, protein in the gut microbiome showed a new function which has been proven to have a significant effect on individuals who suffer from inflammatory bowel disease (IBD). (Related: Microbiome – Gut health discoveries revealed.)

The study by Santamaria and Kathy McCoy, Ph.D., from the University of Calgary’s Cumming School of Medicine (CSM) was published recently in the journal Cell. It was discovered that a new mechanism in the gut microbiome helps regulate both pro- and anti-inflammatory cells. McCoy shared, “We found that a protein expressed by gut bacteria called Bacteroides works to prevent IBD by rapidly recruiting white blood cells to kill a cell of the immune system that is responsible for orchestrating IBD.”

She continued, “We think that this mechanism is likely involved in preventing most people from developing IBD.”

In the immune system, the human microbiome sets the parameters that allow our body to decide what is good and bad for us. The microbiome maintains order and balance in the communities residing within it so that any pathogens waiting to wreak havoc on your body are minimized. Microbiomes also prevent the host system from attacking itself.

But Santamaria warned that the protein can cause white blood cells to overreact when it senses the presence of IBD bacteria, which in turn causes diseases like it. When overstimulated, these white blood cells might even cause autoimmune disorders like diabetes. He added, “This discovery demonstrates the effect the gut microbiome has on the immune system and unearths a novel mechanism via which changes in the gut microbiome can increase the risk of autoimmune disorders. While we looked specifically at IBD, it is likely there are many proteins in the gut that contribute to the development of other autoimmune disorders via similar mechanisms.”

For the gut microbiome to progress, a single bacterium must be isolated within animal models to help rule out other environmental factors. McCoy shared that germ-free mice kick-started her research collaboration with Santamaria.

Before she joined UCalgary, McCoy was studying germ-free mice at the University of Bern, Switzerland. She talked about how Santamaria sent her some of his mouse strains so she can make them germ-free.

McCoy added that they were able to successfully add back single microbial species that “did or did not express the protein in the gut to investigate their effect.” After six years, both Santamaria and McCoy are continuing the work they began on germ-free mice in the hopes of making significant discoveries with positive impacts.

Even though the road to the conclusion of their research is not yet in sight, the two are looking forward to the development of new therapies that can use the power of the gut microbiome to its advantage. In November 2017, the new Western Canadian Microbiome Center (WCMC)’s germ-free facility will open at the CSM. The WCMC is definitely a suitable space to look into the benefits of gut bacteria.

McCoy is also the director of the WCMC, and she is grateful to have the chance to work on “specific gut microbiomes without other environmental variables to consider.” She concluded, “This will help us further this research, as well as complete many other studies into the effects of the microbiome.”

About lijimae2012

My grandmother was a herbalist. She taught me how to mix herbs to cure ailments. I grew up with her from the age of 15 years old. I was going to school  and at the same time returned to her shop of herbs learning different kinds of mixture of herbs and also their names. I have been involved in herbal mixture and I also used it to cure a lot of people who orthodox medicine could not cure even though a lot of people have abused herbal medicine. Selling herbal mixture, popularly called agbo, has also been a great source of income to me and my family. Why I Started This Home Remedies Blog As an educated herbalist , i have been into these work for some years now which  I have help so many peoples. One good-day  i thought about people who are not benefit from these like those outside the Nigeria or peoples who are shame  to seek for a herbalist. Then i decides to create a website so as they can contact me and i would gladly help them. I began this blog in 2017 out of a desire to share my passion for herbs and natural living with others. Above all, am a Muslim and am thankful for the daily love and grace Allah bestows me. I’m glad you’ve visited me here at my home on the web and hope you will join me as I continue down the road to healthier living and my mission to help peoples across the nation! Let’s Connect I would love to connect with you!  Feel free to subscribe to receive free regular post updates in your inbox!  Also, you can find me on facebook, twitter,
