Mouse microbiota more powerfully activates the murine immune system compared to human microbiota

A study published in Nature revealed that immune-regulating bacteria are lost when transplanting microbiota from humans to laboratory mice and that the established human microbiota results in a weak stimulation…

Ketogenic diets could alter the gut microbiota, reduce inflammation

A new study, published in Cell, suggests that ketogenic diets could be used as a therapy for autoimmune disorders of the gut.

How the microbiota shapes the development of the immune system

A. Macpherson et al. reviewed studies that looked at the interaction between the gut microbiota and their mammalian hosts, from fetal development to the early postnatal period.

Gut microbiota could promote lethal immune condition after transplant

Changes in the proportion of some gut bacteria could promote graft-versus-host disease. That’s according to a new study done in mice, published in Science.

Early-life exposure to gut microbes could have long-term effects on immune cells

Early-life exposure to defined microbial communities triggers the development of specific immune cells and influences the abundance of these cells in the skin.

Antibiotics could reduce flu vaccine effectiveness

Disrupting the gut microbiota with antibiotics could affect the immune response to flu vaccination, according to a new study published in Cell.

Gut microbes could boost the activity of immune cells

The gut microbiota could boost the activity of immune cells. That's according to a new study published in the journal Immunity.

Antibiotics can leave the lungs susceptible to flu virus infections

The gut microbiota help to maintain a first line of defense against influenza, while antibiotics can leave the lungs vulnerable, a new study claims.

Changes in the gut microbiota at weaning could prevent inflammatory diseases

At weaning, changes in the gut microbiota trigger an immune reaction that is important for preventing allergies and other inflammatory diseases later in life.

Gut microbiota as a tool to address antimicrobial resistance

In order to manage antimicrobial resistance and enhance immune responses against pathogens, a duo of scientists proposes to turn to the gut microbiota.
