Clonal GZMK+CD8+ T cells are identified as a hallmark of the pathogenesis of cGVHD-induced bronchiolitis obliterans syndrome after allogeneic hematopoietic stem cell transplantationResearch in context
Summary: Background: Bronchiolitis obliterans syndrome (BOS) is one of the most devastating outcomes of chronic graft-versus-host disease (cGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). This remains an area of unmet clinical need for optimal therapy for BOS patients pa...

| description | Summary: Background: Bronchiolitis obliterans syndrome (BOS) is one of the most devastating outcomes of chronic graft-versus-host disease (cGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). This remains an area of unmet clinical need for optimal therapy for BOS patients partly due to the limited understanding of pathogenic mechanisms. Methods: We collected blood samples from 22 patients with cGVHD and 11 patients without cGVHD following allo-HSCT. By applying a combination of mass cytometry (CyTOF), RNA-sequencing and the quantitative cytokine array, we discovered a new cellular hallmarker of patients with cGVHD-BOS. This finding was further validated in cGVHD-BOS murine models by using single-cell RNA sequencing (scRNA-seq) and paired single-cell V(D)J sequencing analyses. Findings: We revealed that circulating Granzyme K (GZMK)-expressing CD8+ T cells with increased expression of CCR5 were accumulated in cGVHD-BOS patients, and GZMK can induce the expression of fibrosis-essential proteins, collagen type I alpha 1 chain (COL1A1) and fibronectin (FN1), in human fibroblasts. As compared to those of control mice, GZMK+CD8+ T cells in the lungs of cGVHD-BOS mice were undergoing significant infiltration and clonal hyperexpansion, with more cytotoxic, pro-inflammatory, migratory and exhausted phenotypes. Moreover, we screened small-molecule drugs and revealed that Bosutinib, the second-generation BCR-ABL1-targeting tyrosine kinase inhibitor (TKI), could inhibit GZMK expression in CD8+ T cells and reduce lung stiffness and pulmonary fibrosis in cGVHD-BOS mice. Interpretation: This study provides proof-of-principle evidence for clonal GZMK+CD8+ T cells as an unexplored contributor to the pathogenesis of cGVHD-BOS, which can be an underlying biomarker for treatment.
