Gamma interferon (gamma-INF) production was studied and two-color fluorescence flow cytometry analysis was done on the peripheral blood mononuclear cells (PBMC) in allogeneic bone marrow transplant recipients. Gamma INF was not detected in any patients within a year after transplantation whether PBMC was stimulated with PHA or not. A year after transplantation, gamma-INF was produced in the normal level in the stimulated and unstimulated PBMC. The number of suppressor-inducer T cells (CD4+2H4+) was decreased and that of suppressor T cells (CD11+CD8+) was normal. The numbers of helper-inducer T cells (CD4+4B4+) and helper T cells (CD4+2H4-) were normal. The numbers of activated helper-inducer T cells (CD4+HLA-DR+) and suppressor-cytotoxic T cells (CD8+HLA-DR+) were elevated. In the NK cells, Leu7+ CD16-cells were elevated, whereas Leu7+CD16+ cells and Leu7-CD16+ cells were normal. Leu7+CD8+ cells were elevated. These results indicated immunodeficiency after transplantation.
