Development of tolerance after haplocompatible T-depleted bone marrow transplantation
1993
We evaluated proliferative responses in mixed lymphocyte cultures (MLC) following bone marrow transplantation (BMT) in 14 recipients of T cell-depleted haplocompatible parental marrow: 11 for the treatment of severe combined immunodeficiency (SCID), 2 for leukemia and 1 for Wiskott-Aldrich syndrome (WAS). We compared the results obtained in 9 SCID patients and 1 WAS patient with split chimerism (T cells of donor origin, B cells and monocytes of recipient origin) to 4 patients (2 SCID and 2 leukemias) who were full chimeras (T, B and monocytes of donor origin). In the full chimeras, as with the fresh donor PBMC, fresh donor T cells did not proliferate in the MLC to recipient non-T cells (E - )
