Microbiome

The varied community of microorganisms that live in different parts of the body, particularly the gut, is referred to as the human microbiome. These microorganisms are mostly bacteria, but they can also be viruses, fungi, and archaea. These microbial communities are vital for immune regulation, nutrition synthesis, digestion, and pathogen defense. Metagenomics research has shown that homeostasis depends on a healthy, diverse microbiome, whereas dysbiosis, or imbalances in the microbiome, is linked to a variety of illnesses, such as obesity, inflammatory bowel disease, allergies, and neuropsychiatric disorders. The field of microbiome research is growing quickly, providing new information on diet-microbe interactions, probiotic treatments, and personalized medicine.

Global data show why gut microbiomes in industrialized regions look increasingly alike

Researchers studying more than 1 000 adults across 12 countries found that industrialization is one of the strongest forces reshaping the human gut microbiome, reducing diversity and stability. Industrialized and urban populations also showed higher immune and gut stress markers, suggesting physiological consequences of these altered microbial communities.

Gut neurons control immunity attack or repair

Beneath the surface of your gut lies a vast network of neurons—as many as in your spinal cord. New research from the Champalimaud Foundation (CF) in Lisbon shows that in mice this "second brain" helps decide whether the immune system should go into attack mode or start repairing tissue.
