| Research Abstract |
1.Repeated transfection of the human hepatocyte growth factor (HGF) CDNA into skeletal muscle inhibited apoptosis of intestinal epithelial cells and donor T-cell infiltration into the liver, thereby ameliorating the enteropathy and liver injury caused by acute graft-versus-host disease (GVHD).
2.HGF gene transfection suppressed IFN-y and TNF-a expression the intestine and liver and decreased the serum IL-12.
3.Extramedullary hematopoiesis by donor cells was increased, and the survival rate of GVHD mice was improved by HGF gene transfection.
4.HGF gene transfection did not affect donor T cell responses to host antigens (mixed lymphocyte reaction, CTL activity), thereby promoting leukemia-free survival of GVHD mice (HGF gene therapy separated acute GVHD from graft-versus-leukemia effects).
5.HGF gene transfection promoted immune reconstitution by hematopoietic stem cell-derived donor T cells.
