WebApr 9, 2024 · Anamnestic Response (Memory) As a result of T-lymphocytes recognizing epitopes of protein antigens during cell-mediated immunity, numerous circulating T8-memory cells and T4-memory cells develop which possess anamnestic response or memory. These T-memory cells persist for the remainder of a person’s life. WebMemory T cells are antigen-specific T cells that remain long-term after an infection has been eliminated. The memory T cells are quickly converted into large numbers of effector T cells upon reexposure to the specific invading antigen, thus providing a rapid response to past infection. Memory T cells are either CD4+ or the virus-specific CD8 ...
