Abstract:
The effect of rosiglitazone, an agonist of peroxisome proliferator-activated receptor-γ (PPARγ), was investigated in a mouse parent-to-F1 GVHD model. Rosiglitazone inhibited mixed lymphocyte reactions, inducing enhanced apoptosis in CD4+, CD8+, and B220+ cells, but not in NK1.1+, Mac-1+, CD4+/CD25+ and CD3+/NK1.1+ cells. Rosiglitazone administration prevented GVHD in the liver, skin, spleen and intestine. Rosiglitazone inhibited GVHD-induced increases in serum levels of tumor necrosis factor-alpha, interferon-gamma, interleukin (IL)-6, and IL-12, and the GVHD-induced decreases in transforming growth factor-beta and IL-10. Immunophenotyping of splenic leukocytes demonstrated that while rosiglitazone treatment increased the population percentages of both donor and host CD4+/CD25+ and CD3+/NK1.1+ cells, the treatment resulted in lower fractions of both donor and host CD8+ cells. Rosiglitazone inhibited the GVHD-induced decreases in the expression of phosphatase and tensin homologue deleted on chromosome 10 (PTEN), as well as the GVHD-induced increase in the splenic p-Akt and nuclear factor-kappa B expression. These results indicate that rosiglitazone and PPARγ activation may be useful in protecting the host from GVHD.
