title: Multiple minor histocompatibility antigen disparities between a recipient and four HLA-identical potential sibling donors for bone marrow transplantation.
abstract: A patient with acute leukemia and her family including four HLA-identical siblings were analyzed to select a donor who was not only HLA- but also minor histocompatibility (mH) antigen compatible for allogeneic bone marrow transplantation (BMT). The HLA-A2 restricted mH antigen-specific HA-1, -2, -4, and -5 cytotoxic T-lymphocyte (CTL) clones were used to type the family members for expression of these mH antigens. The patient and one HLA-identical sibling were compatible for these mH antigens. This sibling was selected as the bone marrow donor. The patient engrafted promptly but developed acute and chronic graft-versus-host disease. To study the presence of other mH antigen disparities between recipient and donor, host-versus-graft CTL lines and clones were generated by stimulation of recipient peripheral blood lymphocytes (PBLs) with donor bone marrow cells, and graft-versus-host CTL lines were generated after BMT by stimulation of PBLs of donor origin with recipient bone marrow cells. These CTL lines were cytotoxic to cells from the bone marrow donor and from the recipient, respectively, and to cells from several other family members. T-cell lines, generated from the patient after BMT by stimulation of recipient-derived PBLs with donor bone marrow cells, exhibited no specific cytotoxicity to donor or recipient cells. Chimerism studies after BMT revealed that the PBLs and T-cell lines generated after BMT were of donor origin.(ABSTRACT TRUNCATED AT 250 WORDS)
