Immune recognition of non-self-antigens typically complicates transplantation and engrafting of foreign tissue from an organism of the same species (allografts), resulting in graft reaction. However, there are two general cases in which an allograft may be accepted. One is when cells or tissue are grafted to an immune-privileged site that is sequestered from immune surveillance (like in the eye or testes) or has strong molecular signals in place to prevent dangerous inflammation … WebFeb 9, 2024 · Tolerance is established in polyclonal CD4 + T cells by distinct mechanisms, according to self-peptide expression patterns CD4 + T cell tolerance can be enforced by various mechanisms.
