چکیده

Immune reconstitution of functional virus-specific T cells after allogeneic hematopoietic stem cell transplantation (HSCT) has been intensively investigated. However, the possible role of crossreactivity of these virus-specific T cells against allogeneic targets is still unclear. Theoretically, as in the field of organ transplantation, virus-specific T cells possess crossreactivity potential after allogeneic HSCT. Such crossreactivity is assumed to play a role in graft-versus-host disease and graft-versus-leukemia effects. In this article, we aim to give a comprehensive overview of current understanding about crossreactivity of virus-specific T cells.

نقش ترکیب KIR-HLA در پیوند سلول‌های بنیادی خون‌ساز

Background : Allogeneic hematopoietic stem cells transplantation (HSCT) is a valuable therapy for refractory acute leukemias, leukemias with a high risk for relapse, myelodysplastic syndromes, and chronic myeloid leukemia. HSCT outcome is dependent on several factors, including the stage of disease, degree of human leukocyte antigen (HLA) identity between donor and recipient, conditioning regim...

Targeting PKCθ in alloreactivity and graft-versus-host-disease: unanswered questions and therapeutic potential

Protein kinase C isoform θ (PKCθ) is a key modulator of TCR signaling and mediates activation of NF-κB, NF-AT, and AP-1 transcription factors. Although in vitro studies of PKCθ(-/-) T cells have shown impaired activation responses, in vivo studies indicate that PKCθ requirement is not universal. While PKCθ is important in induction of experimentally induced autoimmune diseases in mice and gener...

MEK inhibitors selectively suppress alloreactivity and graft-versus-host disease in a memory stage-dependent manner.

Immunosuppressive strategies currently used in hematopoietic stem cell transplantation reliably decrease graft-versus-host disease (GVHD) rates, but also impair pathogen-specific immunity. Experimental transplant studies indicate that GVHD-initiating alloreactive T cells reside primarily in naive and central memory T-cell compartments. In contrast, virus-specific T cells comprise a more differe...

Bone Marrow Transplantation in Thalassemia (Part 2)

During the last two decades conventional therapy has improved the prognosis of thalassemia. However, despite such improvement it still remains a progressive disease with treatment-related complications such as hepatitis, liver fibrosis, and cardiac disease. Bone marrow transplantation (BMT) can prevent or delay progression of the aforementioned complications. The importance of clinical research...

Evaluation of narrow band UVB therapeutic effect on chronic mucocutaneous graft versus host disease lesions: A case series

Background: Chronic graft versus host disease (cGVHD) is a major cutaneous complication of bone marrow transplantation (BMT). Although milder forms of this process may be associated with a lower incidence of tumor recurrences, it is mandatory to develop a more efficient and less harmful therapeutic approach.Methods: This case-series study enrolled 7 patients diagnosed with chronic mucocutaneous...
