Contributions of Bim and Nur77 to multiple mechanisms of T cell tolerance following high affinity antigen encounterDownload
Prevention of autoimmune disease requires the elimination or inactivation of T cells that are highly reactive to self-peptides. During T cell development in the thymus, self-reactive thymocytes undergo negative selection upon receiving a high affinity T cell receptor (TCR) signal following...
Examining the origin of peripheral self-reactive T cells and the contribution of Gadd45beta to T cell selection events in the HYcd4 TCR transgenic mouse modelDownload
Thymic negative selection is important for preventing self-reactive T cells from entering the circulation. However, some self-reactive T cell clones can escape negative selection and induce autoimmunity. The molecular pathways that regulate negative selection are currently unclear, but PD-1 and...
The immune system must be able to mount a response against pathogens and transformed cells while remaining tolerant to healthy host tissue. A key process for ensuring this self-tolerance is the negative selection of self-reactive thymocytes. Expression of Programmed Death-1 (PD-1), a...
