In a new study, researchers at the University of Pécs, Hungary used cell secretions known as exosomes to regenerate the thymus, one of the most important organs in the body.
The thymus shrinks as we age
The thymus is arguably one of the most critical organs in the body, and it is where new T cells develop before being trained in the lymph nodes in order to become the soldiers of the adaptive immune system. However, as we get older, the thymus starts to shrink, its ability to create new T cells declines, and the immune cell-producing tissue increasingly turns into fat and wastes away; this process is known as thymic involution.
