When food is scarce, stress hormones direct the immune system to operate in "low power" mode to preserve immune function while conserving energy, according to researchers at Weill Cornell Medicine.

Bacteria in the human gut can directly deliver proteins into human cells, actively shaping immune responses. A consortium led by researchers at Helmholtz Munich, with participation from Ludwig ...

The study of immune inflammatory responses centers on the intricate molecular pathways that both initiate and modulate these processes. Inflammation is ...

Our immune system implements an array of strategies to combat threatening infections. White blood cells called cytotoxic T ...

Plants mobilize their immune defenses far earlier than scientists have believed for decades—and through a previously overlooked early signaling mechanism—according to a new study published in Nature ...

In a new experiment, scientists used virtual reality to show that the brain can sense virtual infection to trigger the body’s immune system, before the first microbe ever makes contact. Study: Neural ...
