Abstract

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a therapeutic approach that restores hematopoietic and immune functions in recipients through the infusion of allogeneic hematopoietic stem cells. It has evolved into an effective form of adoptive cellular immunotherapy, offering curative potential for various diseases, including malignant hematologic disorders, hematopoietic failure syndromes, congenital immunodeficiencies, and genetic metabolic disorders. Immunology plays a pivotal role in allo-HSCT, as post-transplant immunobiology is uniquely characterized by the potential for immune recognition and attack between donor and host cells. This review elucidates the distinctive features of immune reconstitution following allo-HSCT, examines the immunological underpinnings of graft-versus-host disease (GVHD) and the graft-versus-leukemia (GVL) effect, and evaluates how novel therapeutic strategies modulate these immune responses to improve the management of transplant-related complications and enhance patient outcomes. Additionally, the review addresses the challenges in balancing GVHD and GVL effects and outlines potential directions for future research.
