Emerging data from numerous basic studies and clinical trials have showedn that histone deacetylaseHDAC inhibitors can suppress immune-mediated diseases, such as graft-versus-host disease (GVHD), while retaining beneficial graft-versus-leukemia (GVL) effects. These drugs prevent and/or antagonize treat GVHD by modifying gene expression and inhibiting the production of proinflammatory cytokines, regulating the function of allo-reactive T cells, and up-regulating the function and number of regulatory T cells. Some of these drugs may become a new immunotherapiesimmunotherapy for GVHD or and other immune diseases.
