Research ∈ gut bacteria and its importance for our health has made huge advances ∈ recent years. More and more research indicates that gut bacteria and their composition have an enormous influence on our health and could possibly affect the risk of developing everything from obesity and diabetes to autism and schizophrenia. A recently published scientific paper by two of the leading scientists ∈ the field, Professor Oluf Borbye Pedersen and Professor Susan, outlines the future medical perspectives ∈ understanding and exploiting the potential of intestinal bacteria.
Soon, they write, gut bacteria could be used to develop cures for chronic gut infections such as Crohn’s disease and inflammatory bowel disorder. They could even help the body to fight cancer.“Not too many years ago, the research field was just starting out, but today, gut bacteria have become mainstream and we are now on the threshold of being able to exploit the past ten years of basic research to break through to the next stage: pilot studies on people suffering from various chronic diseases,” says Pedersen.
Henrik Bjørn Nielsen has been studying gut bacteria for many years. Nielsen has read Pedersen’s article and he believes that gut bacteria and all other bacteria that live ∈ and on our bodies (the microbiome) have big potential ∈ developing medical treatments.
The role of intestinal bacteria on human health has come to the fore ∈ recent years. In 2016, scientists discovered that the composition of intestinal bacteria can impact asthma. Two years earlier, scientists showed that intestinal bacteria could eliminate autism ∈ mice. Other studies have demonstrated that intestinal bacteria play an important role ∈ the development of obesity. Certain beneficial bacteria can also keep our immune system healthy. Destroying the balance of intestinal bacteria ∈ the gut with antibiotics can therefore leave for populations of harmful bacteria to expand, which can, for example, lead to strep throat, pneumonia, and otitis media (an inflammation of the \middle ear).
In the new article, Pedersen and Lynch cast light on how scientists could use the last ten years of research to develop new treatments ∈ the near future. One of the areas, where gut bacteria could play an interesting role, is ∈ the treatment of some cancers, says Pedersen. “Studies of mice have recently shown that certain species of lactic acid bacteria and bifidobacteria can enhance the effects of immunotherapy ∈ numerous cancers”, he says.
Today, patients with cancer such as melanoma can be treated by immunotherapy, which can work better for some patients than others.The research can potentially explain why the treatment only works for 20 percent of the people treated by immunotherapy. “Scientists have shown that a rich presence of these bacterial species enhance the effects of immunotherapy. It’s really exciting because it suggests that the bacteria secrete molecules that enhance the immunotherapy effects, says Pedersen.
Nielsen agrees that gut bacteria research will lead to a breakthrough ∈ cancer research ∈ the future. “The microbiome contains millions of genes. In comparison, we humans contain only 25,000. There’s a lot of biochemical potential here that we’ve only just begun to be aware of,” says Nielsen.
