Immune System News -- ScienceDaily

Scientists have uncovered important clues to how human T cells combat Mycobacterium tuberculosis, the bacterium that causes TB.

For years, there has been a long-held belief that acute viral infections like Zika or COVID-19 are directly responsible for neurological damage, but researchers have now discovered that it’s the immune system’s response that is behind it.

In a rare but serious complication of cancer, the body’s own immune system can start attacking the brain, causing rapid-onset memory loss and cognitive deficits. What triggers this sudden biological civil war was largely unknown. Now, researchers have …

Treatment with a molecule known as A485 can quickly and temporarily increase levels of white blood cells, a critical part of the body’s immune system, an effect that is difficult to deliver with currently available pharmaceuticals, a new Yale study fin…

During infection, reversible switch permits flexible formation of memory T cells, long-lived blood cells that can remember pathogen encounters and respond upon reinfection.

Scientists may have discovered a new way in which fasting helps reduce inflammation — a potentially damaging side-effect of the body’s immune system that underlies a number of chronic diseases.

Using a DNA-based delivery particle, researchers created a vaccine that can induce a strong antibody response against SARS-CoV-2.

Biological systems can behave as siblings in several ways, including by borrowing something and never giving it back. That appears to be what the human immune system did with a protein that now helps bind and regulate the subunits that make up antibodi…

Researchers have observed rapid and distinct immune system changes in a small study of people who switched to a vegan or a ketogenic (also called keto) diet. Scientists closely monitored various biological responses of people sequentially eating vegan …

Researchers describe how specific gene activity could potentially enhance immune cell production. The researchers wanted to understand the mechanism of why some hematopoietic stem cells produce more immune cells, while other stem cells produce fewer. T…
