Human thymopoiesis produces polyspecific CD8+ α/β T cells responding to multiple viral antigens
13 Feb 2023
Abstract excerpt
T-cell receptors (TCRs) are formed by stochastic gene rearrangements, theoretically generating >10 19 sequences. They are selected during thymopoiesis, which releases a repertoire of about 10 8 unique TCRs per individual. How evolution shaped a process that produces TCRs that can effectively handle a countless and evolving set of infectious agents is a central question of immunology. The paradigm is that a...
