    Study Notes

    Immune Response and Memory Cells

    • Primary immune response involves the formation of antibodies that prevent re-infection
    • Successful primary immune response results in high levels of specific antibodies in blood, lymph, and mucosal surfaces for many months
    • Long-lived plasma cells in the bone marrow or beneath mucosal surfaces maintain high antibody levels, preventing recurrence of seasonal diseases
    • Long-lived memory T and B cells sustain immunological memory of a pathogen
    • Memory cells, including memory CD8 T cells, memory CD4 T cells, and memory B cells, are crucial during secondary immune responses
    • Memory cells are more abundant and easily activated compared to naive lymphocytes
    • Memory B cells are isotype switched, high affinity, and can continue isotype switching/affinity maturation during subsequent infections
    • Memory B cells express distinguishing features such as isotype switched/affinity-matured receptors and CD27
    • The activation of naive antigen-specific B cells is suppressed during secondary immune responses due to the binding of immune complexes to inhibitory receptors
    • Memory B cell responses in secondary immune responses are similar to and different from primary responses
    • Memory T cell responses are similar to and different from primary responses, with differences in activation and circulation in peripheral tissues
    • Two subsets of memory T cells, central memory T cells and effector memory T cells, are defined based on their characteristics and functions
