For those who live with ulcerative colitis, the disease is a story of two betrayals: the gut's protective wall crumbles, and the microbial community within falls into disarray. Scientists have now found that tiny vesicles shed by a beneficial bacterium native to the human intestine may be capable of reversing both failures at once — not by overriding the body's systems, but by restoring a conversation between host and microbe that evolution has been refining for millennia. The findings, demonstrated in mouse models, suggest that the gut's own bacterial residents may carry within them the seeds
