Our immune system spans two worlds—innate and adaptive. Innate immune cells are like troops at the gate ready to hold off invaders and raise the body's alarms. Adaptive immune cells are specialists ...

A new review by Dr. Ruyuan Wang and an international team of researchers explores the complex interactions between the innate and adaptive immune systems, shedding light on regulatory mechanisms in ...

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 ...

Scientists generally agree that eukaryotes, the domain of life whose cells contain nuclei and that includes almost all multicellular organisms, originated from a process involving the symbiotic union ...

When a transplanted organ arrives, it’s like a controlled burn that risks becoming a wildfire. The body’s innate immune system senses damage signals, like heat shock proteins (HSP70), and sounds the ...

Your immune system is your body’s built-in defense network, working nonstop to protect you from bacteria, viruses, and other harmful invaders. Your immune system includes two main parts: the innate ...

The immune system can work in two ways: the innate immune system reacts to any foreign invaders that are identified by immune cells that look for such pathogens; but the acquired or adaptive immune ...

The immune cell repertoire is composed of many different cell types that are orchestrated in response to infection and other pathogens that enter the body. As a result, the body can defend itself ...
