Application of proteomics to graft-versus-host disease: from biomarker discovery to potential clinical applications
Introduction: Graft-versus-host disease (GVHD) is a frequent and potentially life-threatening complication that occurs in many patients who undergo hematopoietic stem cell transplantation. In an effort to develop blood and tissue-based biochemical assays for GVHD diagnosis, high throughput proteomic platforms have been widely utilized for the identification and validation of disease biomarkers for both acute and chronic GVHD.
Areas covered: This article reviews biomarker research findings on acute and chronic GVHD ascertained by studying peripheral blood, urine and saliva that gives biological information on systemic or localized disease. While the primary focus of GVHD biomarker discovery has been on identification and validation of prognostic and predictive biomarkers that might allow stratification of disease risk, molecular biomarkers that might aid patient diagnosis and/or response to treatment have also been reported.
Expert commentary: Unbiased as well as targeted proteomic studies of acute and chronic GVHD have identified some distinguishing features of the two diseases especially the role of certain immune cell populations. A combination of patient risk stratification using panels of biomarkers and the application of novel targeted therapeutics should help to reduce the burden of GVHD, and hence improve the quality of life for patients following hematopoietic stem cell transplantation.
