The thymus was known to the ancient Greeks, and its name comes from the Greek word θυμός (thumos), meaning "anger", or in Ancient Greek, "heart, soul, desire, life", possibly because of its location in the chest, near where emotions are subjectively felt; [31] or else the name comes from the herb thyme (also in Greek θύμος or ...

To celebrate, ThymiStem in collaboration with animator Cameron Duguid have created a beautiful, hand drawn animation explaining the function of the thymus, an essential organ of the immune system. The video shows how T cells, a type of white blood cell, go through a complex journey in the thymus to become mature immune cells ready to fight off ...
Major function of cTECs is to positively select those T cells that are capable to recognize and interact with MHC molecules on their surface [3]. Once T cell precursors enter the thymic cortex, they start their transformation from double negative stages (T cell without surface expression of CD4 and CD8 co-receptors) to a double positive stage (T cell with surface expression of both co ...
Thymus stromal cells are subsets of specialized cells located in different areas of the thymus. [1] They include all non-T-lineage cells, such as thymic epithelial cells (TECs), endothelial cells, mesenchymal cells, dendritic cells, and B lymphocytes, and provide signals essential for thymocyte development and the homeostasis of the thymic stroma.
FibroBiologics intends to develop this technology as a subcutaneous injection of an allogeneic fibroblast-based organoid to restore thymus function lost due to age-related natural thymus involution, and for a rapid restoration of the immune system in patients who have gone through chemotherapy.
Thyroid function tests will help reveal whether the nodule produces excess thyroid hormones. A radioactive iodine uptake test can help reveal the activity and location of the cancer and metastases. [67] [69] Thyroid cancers are treated by removing the whole or part of thyroid gland. Radioactive Iodine-131 may be given to radioablate the thyroid.
Thymic involution is the shrinking of the thymus with age, resulting in changes in the architecture of the thymus and a decrease in tissue mass. [1] 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.
