NewsDouble trouble: Tobacco use and Long COVID
Researchers investigating the relationship between Long Covid symptoms and smoking by tobacco type found that certain symptoms correlated with different forms of smoking.

NewsStudy identifies blood protein albumin as key defense against deadly fungal infection ‘mucormycosis’
A new study has identified albumin as a powerful and previously unrecognized defense against a rare but often fatal fungal infection. Patients with mucormycosis had markedly lower levels of albumin compared with patients suffering from other fungal infections.

NewsHow a single gene shapes gut health and IBD risk
Two recent studies highlight the role of a gene called PTPN2 in protecting the gut from harmful bacteria linked to inflammatory bowel disease (IBD). When PTPN2 does not function properly, the gut becomes more vulnerable to infection and inflammation.

NewsChemotherapy rewires gut bacteria to curb metastasis
Researchers report that chemotherapy-induced damage to the intestinal lining alters nutrient availability for gut bacteria, reshaping the microbiota and increasing the production of indole-3-propionic acid (IPA), a tryptophan-derived microbial metabolite.

NewsOral bacterium may promote breast cancer development and spread
Researchers found that Fusobacterium nucleatum, an oral bacterium commonly associated with periodontal disease, can promote breast cancer initiation, tumor growth and spread by inducing DNA damage and altering cancer cell behavior.

NewsScientists discover novel immune ‘traffic controller’ hijacked by virus
Researchers have discovered a tissue protein that acts as a central ‘traffic controller’ for immune cells and can be hijacked by a virus to weaken immune responses. Cytomegalovirus (CMV) can hijack this system by producing a protein that blocks CD44 function on stromal cells.

NewsHidden mpox exposure detected in healthy Nigerian adults, revealing under-recognized transmission
The mpox virus appears to be circulating silently in parts of Nigeria, in many cases without the symptoms typically associated with the disease, according to new research.

NewsHuman nasal passages defend against the common cold and help determine how sick we get
Researchers demonstrate how the cells in our noses work together to defend us from the common cold and suggest that our body’s defense to rhinovirus—not the virus itself—typically predicts whether or not we catch a cold, as well as how bad our symptoms will be.

NewsValneva provides update on Chikungunya vaccine IXCHIQ®
Valneva SE has announced that the company has decided to voluntarily withdraw the biologics license application (BLA) and Investigational New Drug (IND) application for its chikungunya vaccine, IXCHIQ® , in the United States, following suspension of the license by the FDA.

NewsShingles vaccine linked to slower biological aging in older adults
Shingles vaccination not only protects against the disease but may also contribute to slower biological aging in older adults, according to a new study.

NewsProject to combat childhood diarrhea receives over 5 million euros
A new project will use probiotics, improved education in hygiene and advanced mathematical models to prevent children from dying of diarrhea in low and middle-income countries.
-
NewsInfant gut bacteria may be the key to preventing asthma and allergies
A study shows that children are less likely to develop allergies and asthma if, as infants, they are colonized with certain bifidobacteria that produce a substance in the gut - a so-called metabolite - that dampens immune responses to allergens.

NewsShould younger and older people receive different treatments for the same infection?
Scientists find the mechanisms young mice use to fight sepsis become disadvantageous in older age, suggesting age-specific treatments may be necessary in ongoing antibiotic resistance crisis.

NewsGut bacteria molecule boosts lung cancer treatment response
Researchers have discovered a small compound produced naturally by gut bacteria that doubled the response to lung cancer immunotherapy treatment in mice and can now be made into a drug for testing in humans.
-
NewsTB and HIV treatments are not enough for a full recovery
Existing treatments control TB and HIV, but the immune system does not revert to normal, helping explain why people living with HIV remain susceptible to infections and underscoring the need for immunotherapies.

NewsWhen a virus releases the immune brake: New evidence on the onset of multiple sclerosis
A study investigating the links between Epstein-Barr virus and multiple sclerosis shows that EBV can interfere with the control of B cells. One viral protein mimics a crucial “approval” signal that B cells usually require from other immune cells. Self-reactive B cells can then survive even when they should be shut down.

NewsResearch reveals hidden diversity of E. coli driving diabetic foot infections
New research has shed light on the diversity and characteristics of E. coli strains that drive diabetic foot infections, providing the first comprehensive genomic characterisation of E. coli strains isolated directly from diabetic foot ulcers across multiple continents.
-
NewsNew mechanism links Epstein-Barr virus to MS
Scientists investigating the links between the Epstein-Barr virus and multiple sclerosis show that when the immune system fights EBV, certain T cells – which normally attack the virus – can also react to a protein in the brain called Anoctamin-2 (ANO2), a phenomenon called molecular mimicry.

NewsNew test could help pinpoint IBD diagnosis, study finds
A test that rapidly detects signs of inflammatory bowel disease (IBD) in stool samples could improve future diagnosis and monitoring of the condition, a study suggests. The luminescent reporter lights up when it detects a molecule linked to gut inflammation.

NewsA protein found in the GI tract can neutralize many bacteria
The mucosal surfaces that line the body are embedded with defensive molecules that help keep microbes from causing inflammation and infections. One of these molecules, intelectin-2, has broad-spectrum antimicrobial activity against bacteria found in the GI tract.
