EHA Reflections | Hematology Frontier | Professor Song Qingxiao: Breaking New Ground Through Cellular Metabolism—7-Ketocholesterol Offers a Precision Strategy for Steroid-Refractory Acute GVHD
Steroid-refractory acute graft-versus-host disease (SR-aGVHD) remains one of the greatest clinical challenges following allogeneic hematopoietic stem cell transplantation (allo-HSCT). At the 2026 European Hematology Association (EHA) Congress, Professor Song Qingxiao from the Second Affiliated Hospital of Army Medical University presented an oral presentation reporting his team's latest discoveries on the pathogenesis of SR-aGVHD. The study demonstrated that 7-ketocholesterol (7-KC) can restore steroid sensitivity by reshaping T-cell lineage metabolism, providing a novel strategy for pre-transplant risk stratification and individualized intervention. During the meeting, Hematology Frontier interviewed Professor Song to discuss the clinical significance of these findings and their potential to overcome one of the most difficult barriers in SR-aGVHD management.
