Cardiovascular disease, the most common cause of death, is the result of oxygen deprivation as blood perfusion to affected tissue is prevented. To halt the development of the disease and to promote healing, re-establishment of blood flow is crucial. Re…
Bacteria and viruses infect our cells through sugars: Now researchers want to know how they do it
Most infectious bacteria and viruses bind to sugars on the surface of our cells. Now researchers have created a library of tens of thousands of natural cells containing all the sugars found on the surface of our cells. The library may help us understan…
Immune system, not COVID virus, may pose greatest risk to pregnant women
Scientists investigated whether the COVID-19 virus could be affecting placental tissue of infected expectant mothers. Their analysis found that while evidence of the virus in the placenta is rare, the placenta in infected mothers tended to exhibit a mu…
A new method for fighting ‘cold’ tumors
Researchers address cold tumors in new research. Working with mouse models of head and neck cancers, researchers studied the role of T cells in tumor treatment.
Fighting harmful bacteria with nanoparticles
Multi-resistant pathogens are a serious and increasing problem in today’s medicine. Where antibiotics are ineffective, these bacteria can cause life-threatening infections. Researchers are currently developing nanoparticles that can be used to detect a…
Artificial intelligence model predicts which key of the immune system opens the locks of coronavirus
A new artificial intelligence (AI) method is helping researchers link immune cells to their targets and, for example, uncouple which white blood cells recognize SARS-CoV-2. The tool has broad applications in understanding the function of the immune sys…
SARS-CoV-2: Infection induces antibodies capable of killing infected cells regardless of disease severity
Researchers demonstrated that SARS-CoV-2 infection induces polyfunctional antibodies. Beyond neutralization, these antibodies can activate NK cells or the complement system, leading to the destruction of infected cells. Polyfunctional antibodies were f…
Shift-work causes negative impacts on health, affects men and women differently
Shift-work and irregular work schedules can cause several health-related issues and affect our defense against infection, according to new research.
New insights on inflammation in COVID-19
Severe cases of COVID-19 can involve extensive inflammation in the body, and clinicians have wondered if this state is similar to what are called cytokine storm syndromes. A new study indicates that different markers in the blood clearly differentiate …
The immune link between a leaky blood-brain barrier and schizophrenia
Research points to the involvement of the immune system the brain as a contributor to mental disorders such as schizophrenia.
