How Gut Holds Keys to Revolutionary Treatments

TEHRAN (ANA)- Researchers at Hudson Institute of Medical Research have developed a novel computational method to understand the gut microbiome, challenging previous beliefs about Crohn’s Disease and paving the way for targeted microbial therapies.

The more diverse species in your gut, the better it is for your health. Now an international team led by the Hudson Institute of Medical Research has found a way to determine which species are important and how they interact to create a healthy microbiome, the journal Nature Communications reported.

Understanding these relationships opens the door to a new world of medical opportunities for conditions from Inflammatory Bowel Disease to infections, autoimmune diseases, and cancers.

Associate Professor Samuel Forster and his team at Hudson Institute of Medical Research, working with collaborators from the Institute for Systems Biology in the USA and local collaborators at Monash University and Monash Health, have spent years studying the gut microbiome and working out which species perform which functions.

He says now it’s possible to map not just what’s there but how they interact and how that can affect the whole body.

“There are roughly 1000 different bacterial species in a healthy gut — it’s a microscopic multicultural community with over a trillion individual members,” A/Prof Forster said.

“Bacteria in our microbiomes exist as communities that rely on each other to produce and share key nutrients between them,” he said. “We have developed a new computational way to understand these dependencies and their role in shaping our microbiome.”

“This new method unlocks our understanding of the gut microbiome and provides a foundation for new treatment options that selectively remodel microbial communities.”

For example, in Crohn’s Disease, the team confirmed the importance of hydrogen sulfide. They discovered that the most likely cause is loss of bacteria that use hydrogen sulfide, not an increase in species producing it, as was previously believed.

The study’s lead author, Dr. Vanessa Marcelino, says a new computational way to study microbial communities was key to establishing these relationships.

“This is a significant step in the development of complex microbial therapies,” Dr. Marcelino said.

“This approach allows us to identify and rank the key interactions between bacteria and use this knowledge to predict targeted ways to change the community.”

A/Prof Forster and his team have a long-standing relationship with Adelaide-based biotechnology company BiomeBank, which is working on new ways to treat and prevent disease by restoring gut microbial ecology.

“Through the partnership between the Hudson Institute of Medical Research and BiomeBank, these insights into community structure will provide the opportunity for targeted intervention with rationally selected combinations of microbes,” he said.
