Webb4 apr. 2024 · T cell development in the thymus involves a series of highly structured procedures, including lineage commitment, T cell receptor (TCR) rearrangement, positive and negative selection, and other checkpoints ( 1 ). Disruption in this process can lead to T cell dysfunction, potentially leading to severe immunodeficiency or autoimmune diseases. WebbT cells undergo positive and negative selection in the thymic cortex and medulla, respectively. A promiscuous expression of a wide array of self-antigens in the thymus is essential for the negative selection of self …
