Chinese scientists decipher the "coding" of gut microbiota, opening up a new pathway for treating human gut diseases.

There are trillions of microorganisms living in the human intestinal tract. In addition to assisting in digestion, some specific bacteria also play a key role in shaping the immune system. In such a complex microbial community, how does the human body accurately identify useful specific bacteria while also resisting harmful pathogens? Recently, Chinese scientists have successfully decoded this puzzle, revealing a new mechanism of host recognition of intestinal flora regulation of immunity, and have found a protein that helps enhance intestinal immune defense. This achievement was published on the 14th in the international academic journal "Nature".
