Gut-Brain Connection

The gut houses about 70% of our immune system, creating a complex interplay between the brain, gut, and immune responses. Stress can modulate this connection, influencing immune activity even without microbial involvement. Additionally, the vagus nerve serves as a crucial communication pathway, relaying signals between the gut and brain, particularly during immune activation. The role of microbes in maintaining the gut barrier and synthesizing mucus further highlights their importance in this intricate system.
