Characterization of donor and recipient CD8+ tissue-resident memory T cells in transplant nephrectomies.

ABSTRACT: Tissue-resident memory T (T_RM) cells are characterized by their surface expression of CD69 and can be subdivided in CD103+ and CD103- T_RM cells. The origin and functional characteristics of T_RM cells in the renal allograft are largely unknown. To determine these features we studied T_RM cells in transplant nephrectomies. T_RM cells with a CD103+ and CD103- phenotype were present in all samples (n = 13) and were mainly CD8+ T cells. Of note, donor-derived T_RM cells were only detectable in renal allografts that failed in the first month after transplantation. Grafts, which failed later, mainly contained recipient derived T_RM cells. The gene expression profiles of the recipient derived CD8+ T_RM cells were st
