Gut bacteria may contribute to susceptibility to HIV infection, UCLA-led research suggests
New UCLA-led research suggests certain gut bacteria — including one that is essential for a healthy gut microbiome – differ between people who go on to acquire HIV infection compared to those who have not become infected. The findings, published in the peer-reviewed journal eBioMedicine, suggest that the gut microbiome could contribute to one’s risk for HIV infection, said study lead Dr.
Histamine-producing gut bacteria can trigger chronic abdominal pain
The McMaster-Queen’s research team pinpointed the bacterium Klebsiella aerogenes as the key histamine producer by studying germ-free mice colonized with gut microbiota from patients with IBS. They also colonized some mice with gut microbiota from healthy volunteers as a control group.
The study found that the bacterium Klebsiella aerogenes converts dietary histidine, an essential amino acid present in animal and plant protein, into histamine, a known mediator of pain.
Bacterial Bullseye
The study findings suggest possibilities for developing new drugs that replicate or build on A. muciniphila’s immuno-modulatory activity.
The work provides a model for using traditional techniques to pinpoint how other members of the gut microbiome act on the body.
Mount Sinai Microbiome Lab Joins NIH’s Accelerating Medicines Partnership
The National Institutes of the Health (NIH) has awarded researchers at the Icahn School of Medicine at Mount Sinai a four-year grant to study the role of the human microbiome in rheumatoid arthritis, systemic lupus, and other autoimmune diseases. The grant is part of the NIH’s Accelerating Medicines Partnership® Autoimmune and Immune-Mediated Diseases (AMP® AIM) program, which is designed to speed the discovery of new treatments and diagnostics. It will support the Microbiome Technology and Analytic Center Hub (Micro-TEACH), a multidisciplinary team of researchers at Icahn Mount Sinai and NYU Langone Health.

Chula’s Faculty of Medicine pioneers Thailand’s first research work that studies “Intestinal Microflora Microbiome of the Aged” which gathers basic information at the national level to unlock the relationship between the wellness of the aged and intestinal microflora that can predict risks of diseases and health and the population’s wellbeing.
Geographic differences in gut microbiota boost immunity
Gut reaction: Cornell researchers “humanized” mice with microbiota from three global populations and found that microbial differences alone can impact immune responses.
New Cleveland Clinic Research Identifies Link Between Gut Microbes and Stroke
New findings from Cleveland Clinic researchers show for the first time that the gut microbiome impacts stroke severity and functional impairment following stroke. The results, published in Cell Host & Microbe, lay the groundwork for potential new interventions to help treat or prevent stroke. The research was led by Weifei Zhu, Ph.D., and Stanley Hazen, M.D., Ph.D., of Cleveland Clinic’s Lerner Research Institute.
Removal of Certain Gut Bacteria Leads to Weight Gain
Rockville, Md. (April 22, 2021)—Researchers from the Medical College of Wisconsin (MCW) report in new research that gut bacteria burn a significant percentage of calories from food that we ingest. Those calories then get absorbed and converted to adipose (fat)…
Sugar not so nice for your child’s brain development
New research led by a University of Georgia faculty member in collaboration with a University of Southern California research group has shown in a rodent model that daily consumption of sugar-sweetened beverages during adolescence impairs performance on a learning and memory task during adulthood. The group further showed that changes in the bacteria in the gut may be the key to the sugar-induced memory impairment.
SLU Expert Offers 7 Tips to Maintain a Healthy Gut
ST. LOUIS – The gut is like your second brain and can have a significant impact on your overall health, advises a nutrition expert. Whitney Linsenmeyer, Ph.D., assistant professor of nutrition and dietetics at Saint Louis University and spokesperson for…
Hydrogen peroxide keeps gut bacteria away from the colon lining
An enzyme in the colon lining releases hydrogen peroxide – a known disinfecting compound- to protect the body from gut microbial communities. Findings from the UC Davis Health study points to importance of considering a different approach to treating gut inflammation and bacterial imbalance in the colon.
Surprising Players in Acute Liver Failure Point to Potential Treatment, Weizmann Institute Scientists Find
Liver failure – often due to acetaminophen overdose – is fatal in 80% of cases. The labs of Profs. Ido Amit and Eran Elinav discovered three liver-cell subsets that contribute to disease progression, and found that depleting the microbiome acts on those subsets to reduce liver damage and increase survival rates. The research may lead to treatments for liver failure.
