title: Requirement for matching T cell and B cell subsets in secondary anti-hapten antibody responses.
abstract: The in vitro secondary anti-hapten response to trinitrophenylated keyhole limpet hemocyanin (TNP-KLH) has been investigated using B and T cells from the same or a pool of identically primed syngeneic individuals. The optimum antibody response obtained from B cells of any given animal was seen when the same individual's T cells were used as a helper cell source. This individual preference was lost if secondary challenge in culture was made with TNP on a heterologous carrier, with the helper cells obtained from suitably primed individuals or a pool thereof. These data are interpreted in terms of a network theory for the regulation of immune responses under physiological conditions.
