Breakthrough model simulates human bone marrow function in the lab

Hidden within our bones, marrow sustains life by producing billions of blood cells daily, from oxygen-carrying red cells to immune-boosting white cells.

Scratching found to both aggravate inflammation and boost immune defenses

New research uncovers the dual nature of scratching an itch; although it can worsen skin inflammation, it can also boost immune defenses against bacterial infections at the injury site.

Gut-derived sugars: A potential game-changer for weight management and diabetes

Gut bacteria-produced exopolysaccharides (EPS) help regulate metabolism by modulating gut microbiota, promoting SCFA production, and improving glucose homeostasis. S. salivarius, a key EPS producer, shows potential for obesity and diabetes intervention.

High-speed in-line force mapping unveils E. coli cell division dynamics

Light and electron microscopy have distinct limitations. Light microscopy makes it difficult to resolve smaller and smaller features, and electron microscopy resolves small structures, but samples must be meticulously prepared, killing any live specimens.

Map highlights diagnosis gaps for deadly CNS infections in HIV patients in Africa

A map of deadly infectious diseases known to attack the central nervous system (CNS) of people who are already suffering with HIV has unearthed diagnosis "blank spots" in Africa, according to research published today in The Lancet Global Health .

Is juicing good for your gut? Research shows surprising microbiome changes

Short-term fruit and vegetable juicing causes microbial shifts in the oral and gut microbiome, but these changes are mostly transient and return to baseline after 14 days.

Researchers propose personalized probiotic therapies for inflammatory diseases

A new approach to treating inflammatory diseases through personalized probiotic therapies – also known as precision medicine – has been proposed by researchers at the University of Surrey.

Genetic fingerprint could help predict antibiotic resistance in bacteria

Antibiotic resistance is a global public health crisis responsible for more than a million deaths annually. By 2050, the World Health Organization estimates it could surpass cancer and heart disease as the leading cause of death as more bacteria develop defenses to the drugs designed to combat them.

Oral fecal transplantation could help prevent graft-versus-host disease in stem cell transplant patients

A new study shows that oral fecal microbiota transplantation (FMT) is a feasible and safe addition to preventing graft-versus-host disease in patients undergoing stem cell transplantation for blood cancers.

Research sheds light on resistance to novobiocin in Staphylococcus aureus

Announcing a new article publication for Zoonoses journal. Methicillin resistant Staphylococcus aureus (MRSA) and Vancomycin resistant Staphylococcus aureus (VRSA) are critical pathogens identified by the WHO for their significant drug resistance.

Establishing common nomenclature for mitochondria transfer and transplantation

Most animal, plant and fungal cells contain organelles called mitochondria. These descendants of a primordial bacterial endosymbiont still preserve distinct genes and are known for their ability to create ATP as chemical energy.

Researchers discover link between protein aggregation and bacterial dormancy

Researchers at the VIB-KU Leuven Center for Microbiology and the VIB-KU Leuven Center for Brain & Disease Research revealed a mechanism involving protein aggregation that allows bacteria to enter a dormant state, a phenomenon that is associated with the persistence of infections and the challenge of antibiotic resistance.

Dietary intervention restores gut microbiome and offers protection against chronic diseases

Findings indicate that a microbiome restoration diet improves gut health and reduces chronic disease markers, highlighting its cardiometabolic benefits.

New compound V-161 offers hope in the fight against antibiotic-resistant bacteria

V-161, a novel compound targeting the Na+ -V-ATPase enzyme in vancomycin-resistant Enterococcus faecium (VRE), significantly reduces bacterial growth and colonization.

New discovery sheds light on how bacteria use plasmids to build resistance

An international collaboration has achieved an important breakthrough in understanding the genetic mechanisms that allow bacteria to build resistance to drugs.

EU-funded Vigilant network aims to develop broad-spectrum antiviral drugs

Pandemics threaten both human health and the global economy. Vaccines are an essential part of the fight against pandemics, but they are only available months after the outbreak

Non-industrialized diet improves health and reduces disease risk

Researchers have found that a newly developed diet inspired by the eating habits of non-industrialised societies can significantly reduce the risk of a number of chronic diseases – and are to share recipes with the public.

New study links intestinal protein to food allergy development

When is food simply nourishing and enjoyable, and when does it provoke an allergic reaction? The answer appears to lie in the balance of microbes that live in our intestine - and a specific protein secreted by intestinal goblet cells that influences that balance.

Study reveals how gut bacteria influence immune cell training and inflammation

A study led by David Sancho at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) in Madrid reveals how an increase in intestinal permeability allows the natural gut bacteria to cross the intestinal barrier and reach the bone marrow, where they induce epigenetic changes-modifications that alter gene activity without affecting DNA sequence-in the stem cells that give rise to immune cells.

How gut microbiota impacts childhood obesity

Gut microbiota plays a critical role in childhood obesity by influencing energy metabolism, inflammation, and appetite regulation, with emerging therapeutic strategies like probiotics, dietary interventions, and fecal microbiota transplantation showing promise.
