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.

A study reveals a molecular pathway linking exercise to an amped-up immune response to pancreatic cancer and greater responsiveness to treatment.

The results could help guide the design of new vaccines for the disease.

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

Because most people are vaccinated against tetanus as children, delivering benign bacteria carrying a tetanus antigen into pancreatic tumors makes them visible to memory cells in the immune system, researchers report.

A study identifies a gene that appears to be partially responsible for the health effects of a limited diet.

Specialized immune cells generated in vivo reduce cardiac scar tissue in mice, a new study shows.

The mitochondria stolen via these tiny connections give tumor cells a metabolic boost while the T cells are left weakened, according to in vitro experiments.

It’s unclear whether differing odds of dying between men and women reflect inherent differences between male and female immune systems or differences rooted in gender norms.

Scientists show that an influx of noradrenaline can halt immune cells in mice.

Scientists are on the hunt for a shot that will protect against not only SARS-CoV-2, but other members of its family that may emerge in the future.

Scientists use a protein found in mucus membranes to ferry vaccines to the lymph nodes.

By avoiding the production of antibodies, something vaccines ordinarily induce, the immunization sidesteps the problem of antibody-dependent enhancement, which can amplify infection by a similar virus and is known to occur with dengue and Zika.
