Functional Analysis of Alloreactive Helper T Cells Involved in the Induction of Cytolytic T Cell Responses In Vitro

1984

When T-responder cells are sensitized in vitro to foreign antigen presented on syngeneic cells or towards allogeneic stimulator cells, a proliferative response is initiated in which antigen specific cytotoxic T lymphocytes (CTL) are generated. The induction of CTL, however, requires the collaboration between functionally distinct T cell subpopulations1–5 and accessory cells from the macrophage lineage, including dendritic cells. The experimental data accumulated so far reveal a cascade of T-T cell interactions and distinct functions of their soluble products resulting in the “Interleukin concept”6 (Fig. 1). Upon receptor-antigen interaction, the “antigen-selected” clones of CTLp become sens…
