IMMUNOLOGY Early Help in Programming Immune Memories

To generate a convincing humoral immune response to infection, most antibody-producing B cells must receive assistance from CD4+ helper T cells. By contrast, the primary response of many CD8+ T lymphocytes shows little dependence on T cell help, and there has been debate whether the same holds true for memory CD8+ T cells. Sun and Bevan and Shedlock and Shen show that vigorous CD8+ T cell memory in mice depends heavily on CD4+ T cell help, although this reliance develops specifically during primary rather than secondary responses. Thus, initial priming of CD8+ T cells to antigen appears to represent a crucial juncture in the production of efficient immunological memory to infection and vaccines.
