To investigate donor CD8+ T cell differentiation and the impact on graft-vs-host-disease (GVHD) after aHSCT.
Analysis of CD8+ T cells in preclinical murine models of aHSCT
Examination of clinical aHSCT samples
Evaluation of T cell activation and inhibitory marker co-expression
Identified decreased memory phenotype of donor alloreactive CD8+ T cells
Increased expression of inhibitory markers linked to T cell exhaustion
Established a connection between persistent alloantigen stimulation and GVHD severity

This research demonstrates the role of T cell exhaustion in graft-vs-host-disease affecting hematological malignancies.

Gallardo et al. (2025) studied this question.
