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 ...

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

Our immune system is divided into two main branches: innate and adaptive. Innate immune cells act as a first line of defense, quickly responding to invaders, while adaptive immune cells take a longer ...

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 ...

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 ...

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 ...

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 ...

What keeps some immune systems youthful and effective in warding off age-related diseases? In a new paper published in Cellular & Molecular Immunology, USC Stem Cell scientist Rong Lu and her ...

Multicellular organisms are a mosaic of different cells, tissues, and systems, each with their own specific function and interactions with other cells within the organism and/or the larger environment ...
