Histamine-Producing Gut Microbes Can Trigger Flareups in Mouse Models of IBS
Researchers have discovered a gut bacterial ‘super-producer’ of histamine that can cause pain flare-ups in some patients with irritable bowel syndrome (IBS).
Impact of Urbanization on Water Sources Revealed by Bacterial Community Signatures
A bacterial community study has shown that urbanization introduces large amounts of nutrients, chemical pollutants and antimicrobial products into water bodies, promoting growth of human pathogenic bacteria with as yet unknown consequences.
Cancer Cells Make Unique Form of Collagen To Protect Against Immune System
Researchers have discovered that cancer cells produce their own unique form of collagen that protects against immune responses. The abnormal collagen is fundamentally different from normal collagen, providing a highly specific target for therapy.
Antibiotics Have Sex-Specific Effects on the Gut Microbiome
Researchers found that antibiotics have sex-specific effects on the gut microbiome makeup of male and female laboratory rats, which could have implications for use in humans.
How the Gut Microbiome Can Influence Cancer Immunotherapy Response
Researchers have demonstrated how machine learning models can reveal interactions between a patient's gut microbiome and their response to immunotherapy, in findings that may ultimately improve cancer patient outcomes.
Carotenoid-Rich Diet Could Improve Women's Health
Research suggests that rates of illness in women can be improved by a diet high in pigmented carotenoids such as yams, kale, spinach, watermelon, bell peppers, tomatoes, oranges and carrots, particularly for preventing visual and cognitive loss.
How Gut Microbes Can Evolve and Become Dangerous
According to a study, gut bacteria can evolve over time, becoming more pathogenic by gaining the ability to migrate across the gut barrier and persist in organs outside of the intestine, thereby driving chronic inflammation and associated pathologies.
Alterations in Gut Bacteria and Blood Bile Acids Are Associated With Severity of Fibromyalgia Symptoms
According to a study, alterations in the gut bacteria and blood bile acids of women with fibromyalgia are associated with the severity of their symptoms.
Could Human Breast Milk Balance Your Gut Microbiome?
In this interview, Gregory J. McKenzie, PhD, discusses the impact of antibiotics, the introduction of new bacteria into the microbiome and the potential of human breast milk-based therapeutics.
