NewsGut microbiome changes during pregnancy may influence immune system response
During pregnancy, changes in levels of cytokines - immune system proteins important in inflammation - may be linked to specific alterations in the mother’s gut microbiome and in plasma and fecal metabolites.

NewsUnique tumor-related bacteria tied to young-onset colorectal cancer, study reveals
New research has mapped changes in tumor-related bacteria to uncover potential new strategies to combat the rise of young-onset colorectal cancer (CRC) in people under the age of 50.

NewsGut bacteria can process dietary fiber into an anti-allergy weapon, new study finds
Researchers investigate how short-chain fatty acids modulate the immune response, paving the way for potential allergy treatments.
-
NewsCommon food preservative has unexpected effects on the gut microbiome
Analysis of a common preservative used to kill pathogens in food shows that it affects beneficial bacteria as well, threatening the healthy balance of the gut microbiome.
-
OpinionTemper the hype of human microbiome studies
As biotechnology has evolved, our understanding of the microbiome has also increased. However, there are still many unknowns and prevailing misconceptions awaiting further exploration.

NewsResearch to advance understanding of deadly disease that affects premature babies
Three researchers have earned more than $5 million in grant money to study causes and potential treatments for necrotizing enterocolitis, a deadly intestinal disease that primarily affects infants born prematurely.
-
NewsSwitching to vegan or ketogenic diet rapidly impacts immune system - and gut microbiome
A study found that switching to a vegan diet prompted responses linked to innate immunity, while the keto diet elicited responses associated with adaptive immunity, along with metabolic changes and shifts in the gut microbiomes.
-
NewsGut microbiota influence severity of respiratory viral infection
The composition of microbiota found in the gut influences how susceptible mice are to respiratory virus infections and the severity of these infections, a new study reveals.
-
NewsProbiotics promote weight loss in obese dogs
Researchers have identified two strains of probiotics that can be used to reduce weight in obese dogs.

NewsStudying defensive bacteria in squid and newts may help human gut health
Elizabeth Heath-Heckman has received a $1.9 million grant to support her research studying the bacteria animals like squid and newts use to protect themselves.
-
NewsStudy in mice uncovers new protective benefit of breast milk
An immune component of breast milk known as the complement system shapes the gut environment of infant mice in ways that make them less susceptible to certain disease-causing bacteria, according to a new study.
-
NewsScientists address debates on postbiotic definition with new paper
A frequent misunderstanding is why microbially-produced metabolites do not qualify as postbiotics.
-
NewsBees synthesize nutrients for the bacteria in their gut microbiome
Two teams of researchers have succeeded in demonstrating that the western honey bee synthesizes nutrients for native gut microbes.
-
NewsGut bacteria combinations protect stem cell transplantation patients from dangerous immune reactions
Researchers have shown that graft versus host disease (GvHD) is less common when certain microbes are present in the gut. In the future, it may be possible to deliberately bring about this protective composition of the microbiome.
-
NewsResearchers identify why cancer immunotherapy can cause colitis
Studies in mice reveal the mechanism that induces this severe side effect and point to a solution that kills the cancer without causing gastrointestinal issues.
-
NewsMolecular link IDed between gut bacteria and excitatory brain signaling in C. elegans
A new study establishes a molecular link between specific B12-producing bacteria in the gut of the roundworm C. elegans and the production of acetylcholine, a neurotransmitter important to memory and cognitive function.
-
NewsStudy shines light on resourceful ways bacteria thrive in the human gut
A survey of bacterial genomes highlights the arsenal of enzymes microbes use to produce energy in the oxygen-poor environment of the gut.
-
NewsConsuming fermented food natto suppresses arteriosclerosis
A study shows that the intake of natto alters the composition of intestinal microflora in a mouse model, regulating the production of cytokines and chemokines associated with arteriosclerosis.
-
NewsA high-fat diet could make you vulnerable to harmful microbes, including Covid
A new study demonstrates that high-fat diets negatively impact genes linked not only to obesity, colon cancer and irritable bowels, but also to the immune system, brain function, and potentially COVID-19 risk.

NewsStudy reveals the relationship of gut microbiome to children’s brain development and function
Emerging evidence implicates the gut microbiome in cognitive outcomes and neurodevelopmental disorders, but the influence of gut microbial metabolism on typical neurodevelopment has not been explored in detail.
