title: Differential cytokine expression in acute and chronic murine graft-versus-host-disease.
abstract: The relationship between acute and chronic graft-versus-host disease (GVHD) is not well understood. While both syndromes appear to result from recognition of host antigens by donor T cells, their pathological changes differ markedly. In light of the recent concept that helper T cells (Th) may be divided into two types based on their cytokine secretion profile and their ability to mediate cellular (Th1) or humoral (Th2) immunity, and considering the inflammatory nature of acute GVHD and the occurrence of significant B cell activation in chronic GVHD, we hypothesized that acute and chronic GVHD may be associated with differential cytokine production by activated T cells. To evaluate this hypothesis, we assessed expression of a range of cytokines in (C57BL/6 x DBA/2)F1 (B6D2F1) recipients of C57BL/6 (acute GVHD), DBA/2 (chronic GVHD) or B6D2F1 (control) spleen cells. The results reported here indicate that a wide range of cytokines, including interleukin (IL)-4, IL-10, interferon-gamma, tumor necrosis factor beta and macrophage inflammatory protein-1 alpha, are indeed differentially expressed in acute and chronic GVHD and support the concept that the pathology peculiar to acute or chronic GVHD may arise due to differential cytokine expression by activated T cells.
