WebOct 7, 2024 · However, central tolerance fails to account for unresponsiveness to antigens which are expressed only in peripheral tissues. Hence, peripheral tolerance mechanisms are induced for maintaining tolerance to such tissue-specific self-antigens. 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-reactive and unrestained T cells responses. When naive T cells exit the thymus, they are in a quiescent state. That means they are in the G…
