NewsCovid persistence in lungs linked to failure of innate immunity
A new study shows that SARS-CoV-2 is found in the lungs of certain individuals for up to 18 months after infection, and that its persistence appears to be linked to a failure of innate immunity (the first line of defense against pathogens).

NewsFungus-fighting protein could help overcome severe autoimmune disease and cancer
A protein in the immune system programmed to protect the body from fungal infections is also responsible for exacerbating the severity of certain autoimmune diseases such as irritable bowel disease (IBS) and type 1 diabetes.

NewsResearchers redesign future mRNA therapeutics to prevent potentially harmful immune responses
Researchers have discovered that misreading of therapeutic mRNAs by the cell’s decoding machinery can cause an unintended immune response in the body, and have found a way to prevent ‘off-target’ immune responses.

NewsVery early antiretroviral therapy within hours of birth could suppress HIV in newborns
A study of more than 50 babies through 2 years old supports evidence that giving antiretroviral therapy (ART) to newborns with HIV within the first days of life can safely suppress amounts of HIV in the blood to undetectable levels.

NewsBroccoli molecule could shape immune defense against Cryptosporidium
Researchers have discovered that a common dietary supplement could protect against chronic Cryptosporidium infections which are particularly prevalent in children under two and in areas with poorer sanitation.
-
NewsPathogens use force to breach immune defenses, study finds
Researchers have discovered a previously unknown process by which pathogens enter a cell with physical force, breaching the body’s immune defenses that prevent infection.

NewsScientists boost vaccines with machine learning to drive more effective treatments
Machine learning guided the discovery of new immune pathway-enhancing molecules and found one particular small molecule that could outperform the best immunomodulators on the market.

NewsFourth dose of COVID vaccine boosts protection in patients with rheumatic disease
A new study suggests that the recommendation for patients receiving disease-modifying antirheumatic drugs to receive a fourth dose of the mRNA vaccine has saved lives and reduced hospitalizations among patients in this high-risk group.

NewsStudy uncovers mediators of persistent HIV viremia
Researchers examining people with non-suppressible HIV viremia (NSV) despite receiving antiretroviral therapy (ART) have found large reservoirs of proviruses inserted into transcriptionally active regions of immune cell genomes.

NewsAlert immune system in respiratory tract protects children from severe Covid
Scientists have discovered that the immune system in the upper respiratory tract is much more alert and active in children before infection than in adults and is therefore better equipped to fight the virus.
-
NewsScientists find an unusual weapon against human cytomegalovirus
Instead of targeting the virus with antiviral treatments, the researchers focused on strengthening the immune system to fight the virus on its own.

NewsBat immune genes protect against COVID and cancer
Bats have acquired remarkable traits throughout their evolution. They’re the only mammals that can fly, and they live much longer than other animals their size. But perhaps most impressive is their robust immune system. It protects bats from viruses that wreak havoc in humans, like COVID-19 or Ebola, and also ...

NewsNew research points out ways to improve tuberculosis vaccines
A new study unveils a previously unappreciated role for a class of immune cells in the early stages of tuberculosis (TB) infection.

NewsCoronavirus vaccination reveals that body builds immune memory in organs
A study of the mRNA coronavirus vaccines reveals that the human body builds local immune memory in various organs. The immune memory cells are more numerous in the organs than in the blood and have enhanced antiviral defense functions.

NewsMicrobiome molecule may hamper immune cells’ cancer-fighting abilities
An important group of immune cells in the large bowel - gamma delta T cells - are crucial to preventing bowel cancer, but a molecule linked to gut microbiome diversity may suppress their immune response.
-
NewsFungal toxin triggers NET traps formed by white blood cells
A new study sheds light on how neutrophils respond to C. albicans hyphae, which release a peptide toxin called candidalysin, exclusively secreted when C. albicans grows as hyphae and hence during invasive growth.
-
NewsPrior exposure to common virus shields against birth defects and miscarriage
A new study uncovers how pre-existing immunity to Cytomegalovirus (CMV) may significantly reduce the risk of birth defects and miscarriage during pregnancy, offering hope for a future vaccine.
-
NewsVulnerability to different COVID-19 mutations depends on previous infections and vaccination
A person’s immune response to variants of SARS-CoV-2 depends on their previous exposure – and differences in the focus of immune responses will help scientists understand how to optimise vaccines in the future to provide broad protection.
-
NewsVersatile vaccine candidate fights measles, mumps and Covid
Altered measles and mumps viruses could be used as a platform to create a trivalent COVID-19 vaccine that triggers immunity to multiple variant strains of the SARS-CoV-2 virus, new research in animals suggests. The study builds upon previous studies that involved inserting a highly stable segment of ...

NewsLeishmania’s secret weapon is ability to infect non-immune cells
The parasites that cause visceral leishmaniasis appear to have a secret weapon, new research suggests - they can infect non-immune cells and persist in those uncommon environments.
