Full-body defense does not always look the way textbooks say it should. In planarian flatworms, a newly identified cell type ...

Among the body's most crucial protective features are the brain barrier systems, including the blood-brain and blood-cerebrospinal fluid (CSF) barriers. These barriers are made of highly specialized ...

A large plasma proteomics study shows that aging patterns in specific cell types may help identify who is more vulnerable to ...

Learn how a blood-based aging test connected youthful brain-support cells with lower genetic risk and older muscle cells with ...

Immunotherapies – treatments that aim to make the body's natural immune system more effective – are becoming more widely used ...

Senescent "zombie" cells are essential architects required to build and maintain the brain's protective barriers.

A detailed cellular study of Crohn's disease has mapped how gene activity changes across more than 50 cell types in the gut. The study provides an open resource of the genes that characterize each ...

Researchers at Peking University have developed DUET, a breakthrough dual-color miniature two-photon microscope that ...

Leukocytes, sometimes referred to as white blood cells(WBCs), are critical to the body’s defense against dangerous pathogens, such as bacteria and viruses, as well ...

Sea stars can produce eggs for up to 200 years. Their surprisingly human-like ovaries may offer clues about fertility and reproductive aging.

Researchers have produced the most detailed map yet of how stem cells in the growing tip of a plant begin their journey to form the many cell types that shape flowers and stems. They identified 18 ...
