NewsResearchers find a way to use antibodies to direct T cells to kill Cytomegalovirus-infected cells
Researchers have found a new way to prompt the immune system to kill cells infected with cytomegalovirus (CMV). They did this by engineering antibodies that direct the immune system’s T-cells to kill cells infected with the virus.

NewsHow an immune cell receptor dampens the fight against fungal infection
People are constantly exposed to fungal spores, including those of Aspergillus fumigatus, but individuals with weakened immune systems may develop life-threatening infections. In a recent study, researchers clarified the mechanisms by which the dendritic cell immunoreceptor (Dcir) suppresses neutrophil activity during infection with A. fumigatus.

NewsSwitching disease on and off: How a gene switch could help against bacterial infections
Researchers show how bacteria actively switch off their disease-causing mechanisms at high cell density and evade the immune system – a potential key to fighting infections better.

NewsDiet rich in vegetable protein and fiber helps maternal and infant health during pregnancy and breastfeeding
A Mediterranean-style diet, rich in fibre, vegetable proteins and healthy fats, benefits maternal health during pregnancy and breastfeeding. It prevents fat accumulation and optimizes the composition of the microbiota in the digestive system.

NewsResearchers uncover how COVID-19 may linger in cancer patients and affect treatment outcomes
New research is providing important insights into how COVID-19 persists in cancer patients even long after testing positive. Researchers studied three cancer patients who had undergone transplant therapies and were hospitalized with severe COVID-19 infections.

NewsA ‘universal’ therapy against the seasonal flu? Antibody cocktail targets virus weak spot
Researchers report that a cocktail of antibodies protected mice—including those with weakened immune systems—from nearly every strain of influenza tested, including avian and swine variants that pose pandemic threats.

NewsWorld-first koala chlamydia vaccine approved
In a world first, a vaccine has been approved to protect Australia’s endangered koalas from infection and death caused by chlamydia.

NewsResearchers reveal infection risks oral mucositis poses to stem cell transplant patients, introduce a superior AI tool to predict them
Researchers have completed a series of studies that reveal how much painful mouth sores known as oral mucositis increase infection risks in stem cell transplant patients and how artificial intelligence can be used to more accurately predict those risks.

NewsStudy reveals how dengue rewires the immune system, reshaping vaccine response
Just as a computer’s operating system can be rewritten after a major update, dengue infection can ‘re-programme’ the body’s immune system, leaving a long-lasting genetic imprint that influences how people respond to future infections—an effect not seen with vaccination.

NewsResearchers map key human proteins that power coronavirus replication, pointing to new treatment strategies
Scientists have pinpointed dozens of human proteins that SARS-CoV-2 needs to complete its full life cycle, from entering a cell to replicating and releasing new viral particles.

NewsGray seals perplex scientists with lack of response to flu infection
Something strange happens when two kinds of seals living in the waters around Cape Cod get infected with influenza – harbor seals get sick but gray seals don’t. This perplexing phenomenon led scientists to investigate if a difference in a piece of the immune system called cytokines could be responsible for this difference.
-
NewsProtein discovery gives new hope for longer COVID protection
Scientists have discovered that the body’s immune system strongly reacts to an internal protein from SARS-CoV-2, the virus that causes COVID-19, which mutates less frequently than the surface-spike protein currently targeted by vaccines.

NewsAntibody-making cells reveal new function in response to flu infection
A study has uncovered a new function of the immune cells that are known for making antibodies. Researchers determined that, in response to flu infection, a specialized set of B cells produce a key signaling molecule that the immune system needs to develop a robust, long-term response to fight off infections.

NewsStudy suggests link between hepatitis B immunity and lower risk of developing diabetes
A research study shows that overall HBV immunity is linked with a 15% lower risk of diabetes, with higher protection in younger people and those with higher immunity shown by higher antibody levels.

NewsTherapeutic vaccination against HPV-related tumors: Nanoparticles make the difference
Researchers have developed a therapeutic vaccination concept that can mobilize the immune system to target cancer cells. Virus peptides coupled to silica nanoparticles can elicit effective T-cell responses against HPV-related tumors. In a mouse model, the nanoparticle-based vaccine was able to partially or completely suppress HPV-related tumors.

NewsOne shot of RSV vaccine effective against hospitalization in older adults for two seasons
One shot of an RSV vaccine protects adults ages 60 or older from RSV-associated hospitalization and critical illness during two consecutive RSV seasons, according to a new study.

NewsCARB-X backs neonatal sepsis diagnostic platform by Quantamatrix
CARB-X has awarded QuantaMatrix Inc. US$2.85M to execute a workplan to develop its rapid diagnostic platform to detect sepsis, especially in vulnerable neonates. The test aims to deliver results within just 6 hours from very small blood samples of 1 to 2 milliliters.

NewsGuideline on respiratory infections in leukemia revised
People with leukemia have a weakened immune system due to the disease itself and treatment, which leads to an increased susceptibility to infections. In a revised guideline, experts summarize the findings of the past ten years on all viruses that cause respiratory infections.

NewsMERIT grant awarded to study cure for HIV
A scientific team has received an NIH MERIT Award to provide long-term grant support to study a handful of people who have managed to clear HIV after a stem cell transplant and those who did not.

NewsPertussis resurgence in Tuscany outlines importance of timely vaccination in Italy
Research analysing 2016-2024 data from all pertussis-related hospitalisations in Tuscany, Italy, finds a ninefold increase in pertussis cases in 2024 among children and adolescents.
