For decades, the thymus has been regarded as a vestigial organ of childhood, essential for T-cell education early in life, but thought to lose relevance as it involutes into fatty tissue after ...

Researchers have identified stem cells in the human thymus for the first time. These cells represent a potential new target to understand immune diseases and cancer and how to boost the immune system.

A raft of research is recasting the thymus from a bit player to a potent regulator of aging and immune health.

It’s long been thought that an organ known as the thymus is crucial to development of the immune system. Early in life, it ensures diversity among immune cells called T cells that fight pathogens and ...

There's a small fatty gland that sits behind your sternum and is often said to be 'useless' in adulthood. A retrospective study, however, suggests the thymus gland is not nearly as expendable as ...

An international research team led by the University of British Columbia (UBC) has uncovered for the first time the importance of a small gland tucked behind the sternum that works to prevent ...

The thymus gland - which produces immune T cells before birth and during childhood - is often regarded as nonfunctional in adults, and it's sometimes removed during cardiac surgery for easier access ...

A small, fatty lump behind your breastbone may hold clues about how long you will live and how well your body fights cancer. Two studies published in Nature in May 2026 reveal that the thymus, an ...

Our immune systems begin developing long before we are born. Immune cells are generated around 4-weeks after gestation and continue to grow while in utero. As a result, we are protected from infection ...

Researchers at the Francis Crick Institute and at University College London (UCL) have rebuilt a human thymus using human stem cells and a bioengineered scaffold. The thymus is an essential organ in ...

One of the most baffling glands in the body is the thymus. It lies just below the neck and behind the top of the breastbone, and in all the centuries that man has been studying physiology, its purpose ...

T cells are incredible. They detect foreign or abnormal proteins with remarkable specificity. Some directly kill cells containing these proteins while others call to additional components of the ...
