Immune reconstitution of CD3/CD4 T cells, NK cells, and B cells. Figure depicts absolute numbers/µL of (A) CD3 T cells, (B) CD4 T cells, (C) NK cells, and (D) B cells at day+28, day+60, day+90, and day+365 after transplantation. Patients under continuous immunosuppression (IS) are compared to patients without continuous IS for absolute numbers of (E) CD3 T cells, (F) CD4 T cells, (G) NK cells, and (H) B cells for the respective time points. A P-value < 0.05 was considered statistically significant.
