Introduction: Childhood cansers are the second leading cause of death among children. Since the incidence and prevalence of malignancies are different in different regions and there are several cultural and environmental factors involved, the aim of this study was investigating epidemiology of common malignancies in children in Hamedan Province during the years of 1386-1395. Methods: In this c...
Studies of the human immune system have been limited by the lack of an appropriate in vivo model. For this reason, efforts have been made to develop murine models with a functional human immune system. We report here that cotransplantation of human fetal thymus/liver tissues and CD34(+) hematopoietic stem/progenitor cells led to the development of sustained human hematopoiesis and a functional ...
Graft-vs.-host (GVH)-related immunosuppression has previously been demonstrated in F1 rodent recipients of parental lymphoid cells, and has been thought to result from an immunologic attack of the donor against the host. Since all cells of such F1 recipients could potentially bear target class I MHC alloantigens, it has not previously been possible to determine precisely the target tissues resp...
Complete interferon-gamma receptor 1 (IFNgammaR1) deficiency is a primary immunodeficiency disease characterized by high susceptibility to recurrent, severe mycobacterial and other intracellular infections. We here report the first successful treatment of the disorder by bone marrow transplantation (BMT). The 8-year-old girl had suffered from recurrent mycobacterial infections in the past and h...
"Mixed chimerism" refers to a state in which the lymphohematopoietic system of the recipient of allogeneic hematopoietic stem cells comprises a mixture of host and donor cells. This state is usually attained through either bone marrow or mobilized peripheral blood stem cell transplantation. Although numerous treatment regimens have led to transplantation tolerance in mice, the induction of mixe...
