It includes deletion of self-reactive lymphocytes by apoptosis , suppression of self-reactive lymphocytes by regulatory T cells (Tregs – a specific type of T lymphocyte with immunosuppressive effects), and induction of anergy (rendering … WebThe major peripheral tolerance mechanisms include T regulatory cells, clonal anergy, and peripheral deletion. Now, the immune response is like a community of cells that fight together. Antigen-presenting cells, like …
WebIn immunology, central tolerance (also known as negative selection) is the process of eliminating any developing T or B lymphocytes that are autoreactive, i.e. reactive to the body itself. [1] Through elimination of autoreactive lymphocytes, tolerance ensures that the immune system does not attack self peptides. [2]
