How can trillions of microbes live in our gut without causing a massive immune reaction? Scientists have been researching this question for years..



Summary

Scientists have long puzzled over how trillions of microbes peacefully coexist in our gut without triggering a constant, overwhelming immune response. This delicate balance is crucial for our health, as these microbes aid in digestion and immunity. Research suggests the gut lining forms a physical barrier, limiting microbial access to immune cells. Furthermore, immune cells in the gut exhibit tolerance, suppressing inflammatory responses to harmless bacteria. Understanding this complex interplay is vital for developing treatments for inflammatory bowel diseases and other conditions linked to gut dysbiosis.
