A new study shows human immune systems differ across populations, raising new questions for medicine and global drug research ...

The human immune system has evolved throughout history to effectively recognize and adapt to invading pathogens. To combat disease, the human body employs the immune system composed of two separate ...

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 ...

New imaging reveals a built-in safeguard that allows B cell populations to rapidly expand in germinal centers without introducing deleterious mutations. Germinal centers are high-speed evolution ...

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 ...

Findings from St. Jude Children's Research Hospital demonstrate that virtual memory T cells, a specialized group of immune cells, provide nonspecific immunity for infants early in life. The work stems ...

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 ...

One of the main changes is a loss of the innate immune system's naive T cells, the first line of defense against pathogens, and an increase in the adaptive immune system's memory T cells. This ...

Innate lymphoid cells, which curiously behave like T cells even though they don’t recognize specific antigens, show promise as a potential cancer therapeutic. In the years that followed, other groups ...

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 ...
