Inducible costimulator (ICOS), a member of the CD28 family of costimulatory molecules, is induced on CD4 and CD8 T cells after their activation. ICOS functions as an essential immune regulator and ICOS blockade is a potential approach to immune modulation in allogeneic transplantation. Here, we describe the expression profile of ICOS in dogs and determine whether ICOS expression is up-regulated during chronic graft-versus-host disease (GVHD) and host-versus-graft reactions in the canine hematopoietic cell transplantation model.
