Quantity and Quality Reconstitution of NKG2A+ NK Cells Are Associated with Graft-Versus-Host Disease after Allogeneic Hematopoietic Cell Transplantation

Conclusion: Overall, we herein observed reduced proportions and absolute cell counts of NK cells and NKG2A+ subsets in patients with acute GVHD after allo-HSCT. The causative association between NK cell numbers, NKG2A+ subsets and GVHD remains debatable. Based on our results, speculating that reduced proportions of NKG2A+ subsets in patients after allo-HSCT are associated with acute GVHD due to their interplay with the patient's donor-derived alloreactive T cells is tempting.DisclosuresNo relevant conflicts of interest to declare.
