Abstract

Allogeneic hematopoietic cell transplantation represents an important therapy for certain malignant and nonmalignant diseases. However, graft-versus-host disease (GVHD) is a major cause of mortality and morbidity. The search for agents that can efficiently suppress GVHD has been going on for more than half a century. GVHD is particularly strong in xenogeneic donor-recipient combinations, given the unlimited number of potentially immunogenic antigens donor lymphocytes encounter in the host. Using a hu-nonobese diabetic/severe combined immunodeficiency (hu-NOD/SCID) γ-null model of xenogeneic GVHD, we have demonstrated that treatment with recombinant immunoglobulin-like transcript 3-Fc protein induces the differentiation of CD8+ T suppressor cells and blocks the cellular and humoral arm of the GVH reaction.
