Abstract

The chemokine receptor CCR5 plays roles in the trafficking of effector cells towards the site of inflammation. We retrospectively examined the impact of the CCR5 variation (rs1800023, -2086A > G) on transplant outcomes in a cohort of 329 patients who underwent unrelated HLA-matched bone marrow transplantation (BMT) for hematologic malignancies through the Japan Marrow Donor Program. A multivariate analysis showed that the recipient CCR5 -2086A/A genotype was significantly associated with a lower relapse rate but not with the development of graft-versus-host disease (GVHD) or transplant-related mortality, thereby resulting in better disease-free and overall survival rates than other variations. The donor CCR5 -2086A/A genotype was associated with a lower incidence of grades 3–4 acute GVHD, which did not improve the survival outcomes. These findings suggest that the recipient CCR5 -2086A/A genotype affects the induction of the graft-versus-tumor effect without augmenting the development of GVHD. CCR5 genotyping in transplant recipients may therefore be a useful tool for evaluating pretransplantation risks.
