Characterizing tolerance in CD8 T cells in the absence of Bim-mediated clonal deletion to tissue restricted antigensDownload
T cells are part of the adaptive immune system that eliminate pathogen-infected cells, but do not harm healthy cells. Precursor T cells, termed thymocytes, develop in the thymus where they randomly generate and express unique antigen specific T cell receptors (TCR) during the CD4+CD8+ double...
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...
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...
