- The impact of intra-graft T cells on the clinical outcome after allogeneic hematopoietic cell transplantation has been investigated. Most previous studies have focused on the role of alpha beta cells while gamma delta cells have received less attention. It has been an open question whether gamma delta cells are beneficial or not for patient outcome, especially with regards to graft versus host disease. In this study, graft composition of.d cell subsets was analyzed and correlated to clinical outcome in 105 recipients who underwent allogeneic hematopoietic cell transplantation between 2013 and 2016. We demonstrate for the first time that grafts containing higher T-cell proportions of CD8(+) gamma delta cells were associated with increased cumulative incidence of acute graft versus host disease grade II-III (50% vs 22.6%; P = 0.008). Additionally, graft T-cell frequency of CD27(+) gamma delta cells was inversely correlated with relapse (P = 0.006) and CMV reactivation (P = 0.05). We conclude that clinical outcome after allogeneic hematopoietic cell transplantation is influenced by the proportions of distinct gamma delta cell subsets in the stem cell graft. We also provide evidence that CD8(+) gamma delta cells are potentially alloreactive and may play a role in acute graft versus host disease. This study illustrates the importance of better understanding of the role of distinct subsets of.d cells in allogeneic hematopoietic cell transplantation.
