| Research Abstract |
We have analyzed mouse allo-HSCT models to identify the molecular mechanisms and therapeutic targets of bone marrow GVHD and revealed that : 1) B cell suppression is independent of alloantigen expression on non-hematopoietic stromal cells, 2) allo-CD4^+T cells specifically express osteoblast inhibitory factor(OIF), 3) pre-osteoblast cell line differentiation is suppressed in the presence of allo-CD4^+T cells, 4) inhibition of OIF is not sufficient to suppress BM GVHD.
