“It is extraordinary to discover that bacterial fragments act directly on a brain center as strategic as the hypothalamus, which is known to manage vital functions such as body temperature, […]

Gut bacteria linked to immune suppression in pancreatic cancer: study
“Lactobacillus—a type of bacteria thought to promote gut health—can alter the function of immune cells called macrophages in the pancreatic tumor environment and spur cancer growth, the researchers found”
Oral antibiotic use and early-onset colorectal cancer: findings from a case-control study using a national clinical database
“Our findings suggest antibiotics may have a role in colon tumour formation across all age-groups.”
Research finds potential mechanism linking autism, intestinal inflammation
“When a mother experiences an infection during pregnancy and her immune system produces elevated levels of the molecule Interleukin-17a (IL-17a), that can not only alter brain development in her fetus, […]
Ubiquitous food additive alters human microbiota and intestinal environment
New clinical research indicates that a widely used food additive, carboxymethylcellulose, alters the intestinal environment of healthy persons, perturbing levels of beneficial bacteria and nutrients.
Gut Bacteria May Point to Early Detection of Colon Cancer
“New research (from University of Washington School of Medicine) suggests that the presence of certain bacteria in a gut biome may be an indicator of colon polyps that will become […]
Bifidobacteria-mediated immune system imprinting early in life
“Here we show that a lack of bifidobacteria, and in particular depletion of genes required for human milk oligosaccharide (HMO) utilization from the metagenome, is associated with systemic inflammation and […]
Microbiota from Young Mice Improve Cognitive Function in Older Recipients
“Conducting fecal microbial transplants from young mice to old mice, researchers were able to show a reversal of aging-associated differences and a slowing of cognitive impairments.”
Effects of early-life penicillin exposure on the gut microbiome and frontal cortex and amygdala gene expression
Exposing newborn mice to low-dose penicillin led to substantial changes in intestinal microbiota population structure and composition. Transcriptomic alterations implicate pathways perturbed in neurodevelopmental and neuropsychiatric disorders. There also were […]
The intestinal neuro-immune axis: crosstalk between neurons, immune cells, and microbes
“Here, we summarize recent studies investigating the crosstalk between gut-innervating neurons, resident immune cells, and epithelial cells at homeostasis and during infection, food allergy, and inflammatory bowel disease.”
