Immune cells deliver packages of telomeres to T cells, helping them retain their virus-fighting function over time, research suggests.

Several mechanisms contribute to the increased transmissibility of this SARS-CoV-2 variant.

IgA antibodies appear to bind to specific species of commensal gut bacteria in mice, according to a study.

Health data from 5,744 adults over the age of 50 reveals an association between stressors such as discrimination and a relatively small proportion of younger infection-fighting immune cells.

Deletions in the sleepy lizard genome leave it without an important type of T cells found in most other vertebrates.

Researchers find a way to wipe out the brain’s immune cell corps and send in new and improved versions.

The immune cells facilitate healing, but they may also help tumors metastasize to the lungs after injury, a study in mice finds.

Current evidence suggests the treatment does not improve survival or reduce the need for ventilation in COVID-19 patients, the World Health Organization says.

In mice, a kind of immune memory appears to protect the cells against future harm, a finding that could provide insight into treatments for irritable bowel syndrome and other inflammatory digestive conditions.

Researchers report what appears to be the second case of a person’s immune system clearing the virus on its own.

The Northwestern University researcher studies how adaptive immune cells influence neurodegenerative disease.

Researchers link the ability of the cells to bind and present DNA from pathogens and cell death to anemia, which is common in COVID-19, and immune activation.

Pharmaceutical companies ramp up efforts to get the brain’s immune cells to help treat Alzheimer’s disease and other conditions, but not everyone agrees the approach will be effective.
