How a leukemia hijacks the genes needed by blood stem cells

As a child, Lynn Aureli didn't know that a particular genetic change contributed to her acute myeloid leukemia (AML)—an alteration that eventually would help explain the cancer's lack of response to chemotherapy. Nor was ...

COVID booster vaccines: How a third dose may help vulnerable people 'level up' their immunity

COVID vaccines call our immune systems to action, generating antibodies which fight against any contact we have with the virus. Antibodies help to reduce the effects of an infection or even prevent it altogether. Scientists ...

Researchers find immune response to COVID strengthens over time

Immunity from COVID-19 appears to gather strength with more time between vaccination and infection, a new laboratory study from researchers at Oregon Health & Science University suggests. The findings carry implications for ...

Bacterium may decrease effectiveness of immunotherapy

Helicobacter pylori is a bacterium that colonizes the stomach lining and is found in more than half of the global population, making it one of the most widespread bacterial infections in the world.

Probing the genetics of autoimmune disease

There are many forms of autoimmune disease, but by definition they all have one thing in common—they arise when the body's immunological defenses go awry and attack our cells or trigger biochemical changes that lead to ...

Role of lymphatic system in bone healing revealed

It was previously assumed that bones lacked lymphatic vessels, but new research from the MRC Human Immunology Unit at Oxford's MRC Weatherall Institute for Molecular Medicine not only locates them within bone tissue, but ...

Examining COVID-19's long-term effects on the innate immune system

The more severe the COVID-19 infection, the slower the recovery of immune cells, such as the dendritic cells, which are necessary for the activation of the immune system. This is shown by researchers at Linköping University ...

HIV & AIDS

Scientists find potential cellular target for HIV therapies

Researchers at The Herbert Wertheim UF Scripps Institute for Biomedical Innovation & Technology have discovered a protein that appears to play a key role in helping HIV replicate in human immune cells, providing more clues ...

Specific immune response to Epstein-Barr virus discovered

Medical science has not yet been able to explain why the Epstein-Barr virus triggers infectious mononucleosis (IM) in some people with initial infections and not in others. But now, a research team led by Elisabeth Puchhammer-Stöckl, ...

Immunology

Research indicates wider benefit to AstraZeneca vaccine

A review of the COVID-19 vaccine trials indicate that adenovirus vectored vaccines may have non-specific protective effects resulting in significantly reduced all-cause mortality and non-COVID deaths, compared with mRNA based ...

How macrophages use metabolic product to combat Q fever pathogen

Q fever can lead to pneumonia, and can attack several organs at once if it becomes chronic. Treatment with antibiotics is lengthy and only has limited success. But which factors in our immune system protect against chronic ...

A unique window into 'original antigenic sin'

Our immune systems react most strongly to the viral strains we encountered in our childhoods. Scientists call this original antigenic sin (OAS)—the body's first blush with a virus like influenza or COVID being the "original ...
