A new study has revealed that a special group of cells in the intestines tamp down the immune responses caused by exposure to food proteins. Called 'tolerogenic dendritic cells,' these cells enable ...

A newly revealed molecular tug-of-war may have implications for better understanding how a multitude of diseases and disorders—including cancers, neurodegenerative diseases and immune ...

Creating mini mitochondria factories helped recharge damaged cells in a dish, providing proof-of-concept work that could pave ...

Scientists have discovered that our specialized immune cells, called T cells, are what they eat -- their switch from functional to 'exhausted' depends on the switch from metabolizing acetate to ...

Small cell lung cancer, or SCLC, is aggressive, lethal and particularly cruel because chemotherapy initially works so well. But within just a few months, SCLC becomes resistant to drugs and dashes ...

A new study led by Stephen D. Nimer, M.D., director of Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine, shows how a key molecule regulates the ...

Declining immune responsiveness with age may be driven by changes in immune cells — not by inflammation, as previously thought. When you purchase through links on our site, we may earn an affiliate ...

Mitchondria may be "watchtowers" of the immune system, contributing to our defenses against germs. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works ...

During infections, the immune system needs to distinguish foreign antigens that are expressed by invading bacteria and viruses from self-antigens that are expressed by cells of the body. If not, the ...
