Direct evidence that cytokines with chemoattractant properties for leukocytes, chemokines, recruit alloantigen-primed T cells into transplanted allografts has been lacking. We present evidence that neutralization of a single chemokine inhibits T cell infiltration into class II MHC-disparate murine allografts and acute rejection. The chemokines IFN-gamma-inducible protein-10 and monokine induced by IFN-gamma (Mig) are expressed in allogeneic skin grafts during the late stages of acute rejection. Survival of class II MHC-disparate B6.H-2bm12 allografts is prolonged from day 14 to day 55 posttransplant when C57BL/6 recipients are given a short course treatment with an antiserum to Mig. This treatment also inhibits T cell and macrophage infiltration into the allografts. B6.H-2bm12 allografts are also not rejected by IFN-gamma-/- C57BL/6 recipients. Injection of Mig directly into B6.H-2bm12 grafts on IFN-gamma-deficient recipients restores T cell infiltration and rejection. Therefore, the inability of IFN-gamma-deficient recipients to reject the class II MHC-disparate allografts is due to the lack of intraallograft Mig production and alloantigen-primed T cell recruitment to the graft. These results indicate for the first time the potential utility of chemokine neutralization strategies in preventing T cell infiltration into allografts and abrogating acute rejection.

D007371 Interferon-gamma The major interferon produced by mitogenically or antigenically stimulated LYMPHOCYTES. It is structurally different from TYPE I INTERFERON and its major activity is immunoregulation. It has been implicated in the expression of CLASS II HISTOCOMPATIBILITY ANTIGENS in cells that do not normally produce them, leading to AUTOIMMUNE DISEASES.
