Once mature, T cells emigrate from the thymus to provide vital functions in the immune system. [11] [12] Each T cell has a distinct T cell receptor, suited to a specific substance, called an antigen. [12] Most T cell receptors bind to the major histocompatibility complex on cells of the body.
English: 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 ...
Thymic epithelial cells (TECs) are specialized cells with high degree of anatomic, phenotypic and functional heterogeneity that are located in the outer layer (epithelium) of the thymic stroma. The thymus , as a primary lymphoid organ , mediates T cell development and maturation.
Hassall's corpuscles (also known as thymic bodies) are structures found in the medulla of the human thymus, formed from eosinophilic type VI thymic epithelial cells arranged concentrically. These concentric corpuscles are composed of a central mass, consisting of one or more granular cells, and of a capsule formed of epithelioid cells.
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.
