Peripheral tolerance
WebBone marrow chimera experiments established that both hematopoietic and nonhematopoietic sources of Ctsb were sufficient to promote peripheral B cell deletion. The depletion of CD4+ T cells overcame the survival and growth advantage provided by Ctsb deficiency, as did blocking CD40L or removing CD40 from the chronically antigen-engaged … WebPeripheral tolerance enacts the second stage of immune tolerance, safeguarding the body from harmful inflammation when autoreactive cells escape central tolerance selection …
Peripheral tolerance
Did you know?
In immunology, peripheral tolerance is the second branch of immunological tolerance, after central tolerance. It takes place in the immune periphery (after T and B cells egress from primary lymphoid organs). Its main purpose is to ensure that self-reactive T and B cells which escaped central tolerance do not … Zobraziť viac Regulatory T cells Tregs are the central mediators of immune suppression and they play a key role in maintaining peripheral tolerance. The master regulator of Treg phenotype and function is … Zobraziť viac Potentially self-reactive T-cells are not activated at immunoprivileged sites, where antigens are expressed in non-surveillanced … Zobraziť viac Although the majority of self-reactive T cell clones are deleted in the thymus by the mechanisms of central tolerance, low affinity self-reactive T cells continuously escape to the immune periphery. Therefore, additional mechanisms exist to prevent self … Zobraziť viac Since many pathways of immunity are interdependent, they do not all need to be tolerised. For example, tolerised T cells will not activate autoreactive B cells. Without this help … Zobraziť viac WebNational Center for Biotechnology Information
