Scientists at The Wistar Institute have identified a previously overlooked mediator in the body’s response to life-threatening infections: hippuric acid, a metabolite produced when gut bacteria break down polyphenols from berries, tea, and other plant-based foods. The research reveals that this molecule acts as an immune-system amplifier, boosting the body’s inflammatory defenses during early infection but elevating them to deadly levels when infections progress to sepsis.

Published in Cell Reports, the study demonstrates that elevated hippuric acid levels correlate with increased mortality in sepsis patients, while also uncovering the molecular mechanisms by which this metabolite modifies immune re...

Scientists working in the School of Biochemistry and Immunology in the Trinity Biomedical Sciences Institute at Trinity College Dublin have made an important breakthrough in understanding what goes wrong in our bodies during the progression of inflammatory diseases and – in doing so – unearthed a potential new therapeutic target.

The scientists have found that an enzyme called Fumarate Hydratase is repressed in macrophages, a frontline inflammatory cell type implicated in a range of diseases including Lupus, Arthritis, Sepsis and COVID-19.

Professor Luke O’Neill, Professor of Biochemistry at Trinity is the lead author of the research article that has just been published in leading international journal, Nature. He said:

“No-one has made a link from Fumarate Hydratase to infla...

Patients are 20% less likely to die of sepsis because a new AI system developed at Johns Hopkins University catches symptoms hours earlier than traditional methods, an extensive hospital study demonstrates.

The system, created by a Johns Hopkins researcher whose young nephew died from sepsis, scours medical records and clinical notes to identify patients at risk of life-threatening complications. The work, which could significantly cut patient mortality from one of the top causes of hospital deaths worldwide, is published today in Nature Medicine and npj Digital Medicine.

“It is the first instance where AI is implemented at the bedside, used by thousands of providers, and where we’re seeing lives saved,” said Suchi Saria, founding research director of the Malone Center for Engin...

Researchers are developing a ground-breaking method that uses biomarkers to detect sepsis 2 to 3 days before the first clinical symptoms appear. This can significantly increase the chances of survival in cases of blood poisoning by bacteria or fungi.

Whether activating or silencing genes, breaking down defective cells or building new tissue, our body is constantly working to repair itself, even in cases of illness. To fight a disease, our body sends out signals, often long before we ourselves notice the disease...
