The origins of memory t cells
WebbIn vivo, these cells detect the cognate antigen and rapidly produce effector cytokines or became cytotoxic but they do no proliferate much; therefore, the immune response against the antigen may also require large numbers of effectors generated from the pool of central memory T cells, which remain in lymph nodes. 28 As it was expected, after the … WebbIt is proposed that chronic autoantigenic exposure fosters the differentiation of non-pathogenic autoreactive CD8+ T cells into antigen-experienced, memory-like autoregulatory T cells, to generate a “negative feedback” regulatory loop capable of countering pathogenicautoreactive effectors. Autoreactive CD8+ regulatory T cells (Tregs) play …
