Abstract [en]

Acute graft-versus-host disease (aGVHD) and kidney injury are the major complications after allogeneic hematopoietic stem cell transplantation (HSCT). Although the underlying mechanisms for the development of these complications are not yet fully understood, it has been proposed that emergence of aGVHD contributes to the development of kidney injury after HSCT. We have shown previously that aGVHD targets the kidney in a biphasic manner: at the onset, inflammatory genes are up-regulated, while when aGVHD becomes established, donor lymphocytes infiltrate the kidney. Here, we characterize renal manifestations at the onset of aGVHD. Mice receiving allogeneic bone marrow and spleen cells displayed symptoms of aGVHD and elevated serum levels of tumor necrosis factor alpha (TNF-alpha) and interferon gamma (IFN-gamma) within 4 days. There was concurrent kidney injury with the following characteristics: (1) elevated expression of the kidney injury biomarker, neutrophil gelatinase-associated lipocalin (NGAL), (2) accumulation of hetero-lysosomes in proximal tubule epithelial cells, and (3) reductions in alpha Klotho mRNA and protein and increased serum levels of fibroblast growth factor 23 (Fgf23), phosphate and urea. This situation resembled acute renal injury caused by bacterial lipopolysaccharide. We conclude that the onset of aGVHD is associated with kidney injury involving down-regulation of alpha Klotho, a sight that may inspire novel therapeutic approaches.
