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 ...

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 ...

The body has an intricate system to defend against infections where each type of immune cell plays a distinct role. Now, a study led by researchers from the Penn State College of Medicine has ...

In the march of metastasis, a molecular trail of crumbs guides some cancer cells from the primary tumor to establish new ...

It starts with a sneeze. Someone on the subway didn't cover their mouth and now a cloud of invisible invaders hangs in the ...

Inflammation is a vital part of the immune response, but it seems that the system can sometimes go awry, resulting in chronic ...

Telomere damage drives T cell exhaustion. Antioxidants restored their cancer-fighting strength in mice. Tumor environments place heavy stress on immune cells that fight cancer. Limited oxygen, ...

The inflammation-promoting cells emerge only in older mice, researchers found. Although the cells’ precise role is unclear, they display several signatures associated with ‘inflammageing’ — the ...

Certain types of biochemical processes can impair the immune system’s ability to recognize and kill cancer cells. Purdue University’s W. Andy Tao and his associates have developed a new way to study ...

A recent study in Nature examined the effects of gender-affirming hormonal treatment (GAHT) on the immune system in trans gendermen. Men and women differ in their severity levels for infectious and ...
