Class II MHC mutants alter CD4 T-cell V region use [Immunology and Inflammation]>
Edit PNAS 02 Sep 2016
The interaction of αβ T-cell antigen receptors (TCRs) with peptides bound to MHC molecules lies at the center of adaptive immunity. Whether TCRs have evolved to react with MHC or, instead, processes in the thymus involving coreceptors and other molecules select MHC-specific TCRs de novo from a random repertoire is... ....
Clonotype analysis of age-tracked T cells [Immunology and Inflammation]>
Edit PNAS 30 Aug 2016
Homeostatic maintenance of T cells with broad clonal diversity is influenced by both continuing output of young T cells from the thymus and ongoing turnover of preexisting clones in the periphery. In the absence of infection, self and commensal antigens are thought to play important roles in selection and homeostatic... ....
Researchers identify possible pathway to reboot immune system after bone-marrow transplants

Genetic Regulation of the Thymus Function Identified (Universität Basel)
Edit Public Technologies 23 Aug 2016
The results show that Foxn1 not only plays a crucial role in development of the thymus in the embryo, but it also regulates vital functions in the developed, postnatal organ ... Immune cells mature in the thymus, an organ located between the sternum and heart, during the embryonic stage, but they reach full functionality only when they interact with thymus epithelial cells - the teachers of the T cell, so to speak....
Transcription factor Foxn1 and preserving immune function in later life
Edit Science Daily 23 Aug 2016
Among the hundreds of genes whose expression is regulated by Foxn1 are genes essential to attract precursor cells in the blood to the thymus, that commit precursor cells to become T cells, and that provide the molecular machinery which allows T cell selection to best serve an individual ... ....
