title: Adoptive immunity transferred by naive donor cells immunized in vitro.
abstract: Speedy restoration of immune responsiveness in bone marrow recipients has been the objective of studies in which the donor was immunized so that specific immunologic memory could be transferred adoptively and selectively. Using unrelated rabbits, matched for major histocompatibility antigens but mismatched for their immunoglobulin allotypes, it could be shown that recipients of lymphoid cells from naive donors became B cell chimeras but did not use donor-derived B cells for their antibody responses to test antigens. In contrast, cells from donors primed for such antigens dominated antibody production in recipients in response to specific challenge. Clonal restriction in such adoptive responses was demonstrated. We now show that the induction of effective memory in cells from naive donors can be achieved in vitro during the preparation of donor cells for transfer to the recipient. Early challenge of the recipient enhances expression of the transferred immune response quantitatively and also results in the establishment or preservation of a larger diversity of clones from the donor.
