Graft-versus-host disease remains one of the most formidable barriers to complete success hematopoietic stem cell transplantation that has emerged as curative approach for many malignancies because it affects quality life and overall survival. Macrophages are among important members immune system, which perform dual roles in GVHD both therapeutic tools targets. This review epitomizes multifunctional role macrophages pathophysiology acute chronic GVHD. play an early phase their recruitment infiltration into target organs. Furthermore, they polarize two functionally different phenotypes, including M1 M2. In case GVHD, express phenotype characterized by production pro-inflammatory cytokines contribute tissue damage. contrast, tend toward M2 associated with repair tissues fibrosis.
