Viral abrogation of stem cell transplantation tolerance causes graft rejection and host death by different mechanisms.

Mechanisms Rejection and Host Death by Different Transplantation Tolerance Causes Graft Viral Abrogation of Stem Cell

Hematopoietic stem cell transplant therapy, clinical trials, complications, and quality of life for patients with Sickle cell anemia: Clinical potential and future perspectives

Background: Sickle cell anemia (SCA) is an inherited monogenic disorder. The clinical symptoms of SCA are protean, including vaso-occlusion, hemolysis, early stroke, leg ulcers, multi-organ failure, and increased risk of premature death. Hematopoietic stem cell transplantation is the only treatment identified to reduce SCA-related organ damage. Unfortunately, graft rejection is a significant im...

Dendritic Cells in Transplant Tolerance

Dendritic cells (DCs) are a heterogeneous family of professional APCs involved in priming adaptive immune responses. Donor DCs (direct pathway of allorecognition) and recipient DCs presenting processed donor major histocompatibility complex (MHC) as peptides (indirect pathway of allorecognition) participate actively in graft rejection by stimulating recipient T cell responses following organ tr...

Assessment of Cyclosporine Serum Concentrations on the Incidence of Acute Graft versus Host Disease Post Hematopoietic Stem Cell Transplantation

Allogeneic hematopoietic stem cell transplantation (HSCT) is a curative treatment option for hematological disorders. Cyclosporine (CsA) is one of the major immunosuppressive agents for the prophylaxis against graft versus host disease (GvHD). In this retrospective study, we evaluated the effects of CsA serum levels on the incidence of acute GvHD and transplant outcomes. 103 adult patients rece...

Relationship between Molecular Chimerism and Graft Versus Host Disease after Allogenic Hematopoietic Stem Cell Transplantation

Background: Bone marrow transplantation (BMT) is considered as a curative therapy for a broad range of diseases. However, complications such as relapse and graft versus host disease (GVHD) may be observed following BMT. Chimerism analysis serves as a reliable indicator of transplant outcome. Complete chimerism refers to the complete replacement of hematopoietic system by donor cells, while mixe...
