Impaired reconstitution of “memory-like” NK cells and HCMV–specific T cells in patients with Rf/EOD CMVi. HCMV–specific CD4⁺ and CD8⁺ T cells as well as “memory-like” NK cells were quantified in patients with Rf/EOD-CMVi. Individual kinetics of all 7 patients with Rf/EOD-CMVi are shown. CD, cluster of differentiation; PCR, polymerase chain reaction.
