Gut Bacteria Inject Proteins That Control Human Immune System
Scientists have discovered that gut bacteria use microscopic injection systems to send proteins directly into human cells, actively influencing immune and metabolic responses. Even harmless microbes can affect inflammatory disease pathways, including conditions like Crohn's disease. The findings represent a major shift in understanding the microbiome's power over human health.
Gut bacteria aren’t just passive passengers—they can actively send proteins straight into our cells. Using microscopic injection systems, even harmless microbes can influence immune responses and metabolic pathways. Researchers found these interactions may play a role in inflammatory diseases like Crohn’s. It’s a major shift in how scientists understand the microbiome’s power over human health.
