Researchers found a molecular mechanism, shared in cancer and pregnancy, that suppresses the immune system. Block this mechanism, called B7-H4, and the immune system revs up to slow cancer's growth.

Researchers at the University of Liège (Belgium) have uncovered a previously unknown mechanism that regulates the immune response against parasites. During a parasitic infection, specific immune cells ...

A research team at Lund University in Sweden has discovered a mechanism that helps acute myeloid leukemia cells to evade the body’s immune system. By developing an antibody that blocks the mechanism, ...

Stem-cell researcher Carolina Florian didn’t trust what she was seeing. Her elderly laboratory mice were starting to look younger. They were more sprightly and their coats were sleeker. Yet all she ...

Immunotherapy, which uses programmed immune cells to selectively destroy cancer cells, has transformed cancer treatment. However, cancer cells have developed immune evasion strategies, leading to poor ...

New insights into a sophisticated process that protects sperm cells has revealed a mechanism, similar to an immune system, thwarts genetic chaos during the earliest stages of their development.

With every bite of food we take, our intestinal immune system must make a big decision. Tasked with defending us from foreign pathogens, these exquisitely sensitive cells somehow distinguish friend ...
