16 May 2024 By Gillian Dohrn Scientists know there is a link between obesity and some cancers. A study in mice and people suggests why that might be. A Desulfovibrio bacterium. This group of gut bacteria has been linked to a suppressed immune system, which can allow breast-cancer tumours to flourish. Credit: PNWL/Alamy Researchers have...
Chinese Academy of SciencesIn the editorial published on 4 September 2023, in the “gut-liver axis” special issue of the journal Hepatobiliary & Pancreatic Diseases International, Dr. Jian-Gao Fan and Dr. Lu Jiang from Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine provided a comprehensive elucidation of the pivotal role of gut microbiota...
by American Society of Nephrology Credit: Pixabay/CC0 Public Domain New research in rodents indicates that altering gut microbes may affect the development of organ damage associated with hypertension. The findings will be presented at ASN Kidney Week 2023, November 1–5. For the study, scientists used narrow-spectrum antibiotics to specifically deplete Gram-negative or Gram-positive bacteria in rats...
by Ilima Loomis, Harvard Medical School Graphical abstract. Credit: Immunity (2023). DOI: 10.1016/j.immuni.2023.01.033 The human immune system is incredibly versatile. Among its most skilled multitaskers are T cells, known for their role in everything from fighting infection to reining in inflammation to killing nascent tumors. Now, in a surprising new discovery, Harvard Medical School researchers have found that a...

(B) High-sucrose pellets obtained during daily FR1 training sessions of VEH (n =...
by UT Southwestern Medical Center Credit: CC0 Public Domain The role of the microbiome in intestinal and systemic health has garnered close attention among researchers for many years. Now evidence is mounting that this collection of microorganisms in the human gut can also impact a person’s neurological and emotional health, according to a recent perspective...
EUROPEAN ASSOCIATION OF UROLOGY Researchers have found a significant difference in the gut microbiota of men with prostate cancer, compared with those who have benign biopsies. The study is presented at the European Association of Urology annual congress (EAU22), in Amsterdam. Although the finding is an association, it could partly explain the relationship between lifestyle...
14 APR 2022 2:00 PM BY ELIZABETH PENNISI Gut bacteria can influence the brain’s temperature controls and stimulate nest-building in mice. KLEIN AND HUBERT/MINDEN PICTURES With more microbes than cells in our body, it’s not surprising that bacteria and other invisible “guests” influence our metabolism, immune system, and even our behavior. Now, researchers studying mice...
