RESUMO
Graft-versus-host disease (GVHD) is the major cause of morbidity and mortality among patients undergoing allogeneic hematopoietic stem cell transplantation. Although animal models have been clearly established for the study of skin, liver, and gut, currently there is no equivalent experiemental model for analyzing ocular involvement, which is rather common, especially among patients diagnosed with chronic GVHD. In the current study we have developed a murine model of ocular GVHD and, for the first time, we describe the histopathologic features involving cornea and limbus, which could play a role in the physiopathology of the disease at the ocular level. Our results represent a major finding that allows us to define a model for evaluating new therapeutic strategies for treating ocular GVHD prior to their use in clinical setting.
