Master's Theses
Thymic epithelial cells (TECs) are indispensable for T cell development and maturation. Therefore, damages to the thymic epithelial cells are detrimental to thymic function and immune response. In young healthy individuals, TECs have a high regenerative potential and are capable of renewal from serious damage; however, the molecular mechanism of this recovery is unclear. A recent study has shown that IL-22-producing ILCs are present in the mouse thymus and can regenerate thymic epithelial cells following radiation induced injuries. However, it is unknown whether IL-22-producing cells are also found in the human thymus. Thus, the goal of this study is to …

It is known that the elderly are more susceptible to illnesses and infections and respond poorly to immunization. A contributing factor to a decrease in the immune response in the elderly is the decline in the production of naïve T cell by the thymus. In the thymus, the notch receptor expressed on early T cell progenitors (ETP) binds to its ligand expressed on thymic epithelial cells (TEC), signaling ETP to develop through a series of developmental stages before maturing into naive T cells. Because ETP are non-self renewing, the thymus relies on the bone marrow (BM) for a continuous supply …
