CYM does not affect the infiltration of the donor T cells to the GVHD target organs. (a–d) The number of donor- and host-derived CD4+ T cells, CD8+ T cells, NK cells, NKT cells and DCs in the spleen, liver, lung and intestine day 4 post BMT. Donor-derived cells were identified as H2Kb+ cells, and host-derived cells were identified as H2Kd+ cells; the cell subsets were analyzed by CD3+CD4+ for CD4+ T cells, CD3+CD8+ for CD8+ T cells, CD3−NK1.1+ for NK cells, CD3+NK1.1+ for NKT cells and CD11c+ for DCs. (e) The number of CD4+ T cells, CD8+ T cells, NK cells, NKT cells and B cells in blood day 4 post BMT. The data are representative of three independent experiments, each using 4–5 mice per group. Data are shown as the mean±s.e.m. BMT, bone marrow transplantation; DC, dendritic cell; GVHD, graft-versus-host disease; NK, natural killer; NKT, natural killer T.
