WebbIn addition to global decrease in thymic output, the aged thymus outputs T cells that are functionally inferior to those exported from the young thymus, with the deterioration of … WebbAbstractThe thymus medulla is a key site for immunoregulation and tolerance, and its functional specialisation is achieved through the complexity of medullary thymic epithelial cells (mTEC). While the importance of the medulla for thymus function is clear, the production and maintenance of mTEC diversity remains poorly understood. Here, using …
Thymic decline
Did you know?
Thymic involution is the shrinking (involution) of the thymus with age, resulting in changes in the architecture of the thymus and a decrease in tissue mass. Thymus involution is one of the major characteristics of vertebrate immunology, and occurs in almost all vertebrates, from birds, teleosts, amphibians to reptiles, though the thymi of a few species of sharks are known not to involute. This process is genetically regulated, with the nucleic material responsible being an example of a conserved … Webb20 aug. 2024 · Decreased thymic output has also been described in T-cell immunodeficiencies, HIV infection, aging, and autoimmune diseases .
