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.

Fungal pathogens that live harmlessly on and inside the human body are increasingly defeating the limited arsenal of antifungal drugs, while simultaneously dodging the immune system’s surveillance.

How does the same infection, say the flu or a cold, give some people mild symptoms and leave others suffering? Why do people develop autoimmune diseases? And will we ever be able to predict when—and ...

Researchers have engineered Arabidopsis plants that emit visible light when their immune defenses switch on, creating a living sensor that tracks how plants fight pathogens in real time. The work, ...

Our immune systems prevent and limit infections. They are a complex set of organs, cells, tissues and proteins that work together to protect our bodies from harmful invaders such as bacteria, viruses, ...

Cancer immunotherapies, including cancer vaccines, harness and amplify the immune system’s natural ability to detect and attack cancer cells. In this illustration, immune T cells (pink) attach to a ...

You have probably heard that loading up on vitamin C will ward off a cold, or perhaps TikTok has influenced you to take turmeric or some other supplement to supercharge your immune system. The problem ...
