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 ...
Thymulin (also known as thymic factor or its old name facteur thymique serique) is a nonapeptide produced by two distinct epithelial populations in the thymus first described by Bach in 1977. [1] It requires zinc for biological activity. Its peptide sequence is H-Pyr-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn-OH.
TECs, as a component of the thymus, play a key role in thymocyte development and self-tolerance, so their dysfunction causes many autoimmune diseases, tumors of immunodeficiencies. Most frequently are occurred epithelial tumors established from TEC and thymocytes - thymomas and thymic carcinoma.
While cTECs control the functionality of TCRs during the process called positive selection, Medullary thymic epithelial cells (mTECs) that home in the inner part of the thymus- medulla, present on their MHC molecules self-peptides, generated mostly by protein Autoimmune regulator, to eliminate T cells with self-reactive TCRs via processes of ...
The autoimmune regulator (AIRE) is a protein that in humans is encoded by the AIRE gene. [5] It is a 13kbp gene on chromosome 21q22.3 that encodes 545 amino acids. [6] AIRE is a transcription factor expressed in the medulla [broken anchor] (inner part) of the thymus.
