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.

How gut imbalance may drive obesity, diabetes, and heart disease

A new review argues that gut dysbiosis is closely linked to metabolic dysfunction through intertwined effects on inflammation, oxidative stress, gut barrier integrity, microbial metabolites, and epigenetic regulation. It also highlights microbiome-targeted strategies such as high-fiber diets, probiotics, prebiotics, postbiotics, exercise, and fecal microbiota transplantation as promising ways to support metabolic health.

How do diet, smoking, alcohol, and stress reshape the female microbiome?

This review examines how modifiable lifestyle and environmental factors shape the female vaginal, gut, oral, and skin microbiomes, with diet, alcohol, smoking, obesity, stress, hygiene, physical activity, and sexual behaviours all linked to site-specific microbial shifts. It argues that understanding these patterns could help guide future female-focused prevention and intervention strategies.

Natural peptide in sweat may help block flu infection before symptoms start

Researchers led by the Fisabio Foundation found that dermcidin, a natural antimicrobial peptide present in sweat and respiratory tissues, can block influenza infection by binding to a highly conserved region of the viral hemagglutinin protein and preventing cell entry. The study also found that people who did not develop flu-like symptoms had markedly higher baseline dermcidin levels, suggesting the molecule may help reduce susceptibility to infection and could support the development of broader-spectrum antivirals.
