WebOct 19, 2024 · A number of T cell-intrinsic peripheral tolerance mechanisms (quiescence, ignorance, anergy, exhaustion, senescence and cell death) restrain autoimmunity and … WebJan 5, 2010 · We had previously shown that peripheral CD8 + T-cell tolerance induction following the presentation of CD8 + T-cell epitopes on steady-state DCs is a T-cell–intrinsic phenomenon involving deletion or anergy of the T cells recognizing their antigen on steady-state DCs . Antigen presentation in the absence of DC activation did not lead to a ...

Example: If dendritic cells are not appropriately activated and present self-antigen to T cells without signals … WebAccumulating evidence suggests that PD-1, an immuno-inhibitory receptor expressed on activated T cells, regulates peripheral T cell tolerance. In particular, PD-1 is involved in the …
WebAs a result of the disrupted balance of NK cells in the peripheral blood and peripheral organs in IS patients and in animal models of IS, these cells infiltrate the damaged brain. They become an important bridge participating in a complex crosstalk between the immune and nervous system and play a significant role in post-stroke immunodepression ...

WebSelective suppression of effector CD4 + T cell functions is necessary to prevent immune cell-mediated damage to healthy tissues. This appears especially true during pregnancy or in individuals predisposed to autoimmunity.
