Balance of graft-protective regulatory and graft-destructive effector T cells largely depends
on the balance of proinflammatory and anti-inflammatory cytokines in the milieu, in which
donor-directed T-cell response occurs. In the absence of proinflammatory cytokines, the
constitutive expression of TGF-β may guide recipient T cells into a tissue-protective, pro-
tolerant mode. Therefore, targeting adverse tissue inflammation may represent a powerful
means to tilt antidonor immunity towards tolerance.
