Gut microbes may regulate host physiology by metabolizing vitamin A

The results of a new research done in mice suggest that gut bacteria can regulate host physiology by metabolizing vitamin A.

Probiotic Supplement Reduces Alcohol Absorption in Small Intestine

Probiotic supplements with ethanol-metabolizing activity may help reduce the disease burden of excessive alcohol consumption.

Microbiota transplant and IBD: what is missing

Sudarshen Paramsothy (University of New South Wales, Australia) discussed the controversials about FMT in IBD patients.

Specific prebiotics may influence gut microbes in ways that prevent obesity

New research in mice suggests that two MACs, L-arabinose and sucrose, have specific effects on gut microbes that may prevent diet-induced obesity.

IBD, Multiomics approach could pave the way for new therapies

Herbert Tilg (University Innsbruck, Austria) discussed the relationship between Inflammatory Bowel Diseases and gut microbiome.

How gut bacteria may evolve to become harmful

The findings of a new research show that gut bacteria can become harmful over time by gaining the ability to escape the intestine and persist in other organs where they…

Bacterial signatures in gut and airway may be biomarker for COVID-19 severity

The findings of a new research suggest that changes in the microbial composition of people with COVID-19 could be used as a biomarker of invasion of lung pathogens and dysbiosis…

Gut-Brain Theory – Episode 2: The link between gut and depression

Together with Prof. Ted Dinan (UCC Ireland), in this episode we discuss the link between gut and depression.

Niall Hyland: ‘Challenges to unlocking the real potential of gut brain axis’

Niall Hyland (University College Cork) discussed the research on gut brain axis and the potential role of psychobiotics.

IgA antibodies bind to specific gut bacteria in mice

The findings of a new research may inform strategies for treating intestinal diseases by targeting pathogens without killing beneficial gut bacteria.

Could “rejuvenating” the microbiota bring health benefits?

Researchers at Harvard Medical School propose to “rejuvenate” a person’s microbiota by collecting stool samples for future treatment of diseases that could be managed with fecal microbial transplantation (FMT).

Some gut bacteria produce key lipids involved in cell signaling

The findings of a recent study suggest that the production of inositol lipids is common in Bacteroidetes and other gut-associated bacteria, and it may be a means of cross-kingdom communication.

Some viruses alter the skin microbiota of their host to attract mosquitoes

The findings of a recent study suggest that dengue and Zika viruses are able to change their host’s odor by altering the skin microbiota.

Structures of microbial enzymes hint at how these proteins recognize their targets

New research offers insights into how human gut bacteria recognize sulfated glycans. The findings could help to develop interventions for diseases where sulfated glycan metabolism is altered.

Microbiotas of Hadza infants differ from those of infants living in industrialized areas

New research shows that microbiota diversity appears early in infants from nonindustrial populations and could be traced back to their mothers as well as to the local environment. 

Probiotics may help to treat depression

The findings of a small clinical trial suggest that probiotic treatment could be used in combination with antidepressant medication to treat clinical depression.

Specific antibodies in breast milk may help to fight intestinal infections

The findings of a new research suggest that IgG in breast milk promotes immunity against intestinal pathogens and shapes the development of the gut microbiota and immune cells in early…

Microbial signature may help predict who’s more likely to develop fatty liver disease

The findings of a new research reveal the microbiota alterations during NAFLD and suggest that gut microbes can be used as an early clinical sign of the condition.

Similar gut bacteria may influence different gastrointestinal diseases

Researchers have found that some microbes involved in inflammatory conditions produced different effects based on their interaction with different host genes and through different pathways.

Towards a more ethical microbiome research

A human rights activist and a group of anthropologists and human biologists provide suggestions for more inclusive and ethical research practices in microbiome research.
