• Liver bx -- demonstrate the presence of periportal
  lymphocytic infiltrate that extends into the liver
  parenchyma, as well as the invasion of inflammatory
  cells into the vascular endothelium.

  polyclonal anti–T-cell antibodies are effective against
  corticosteroid-resistant rejection, leading to the
  reversal of the acute episode in more than 90% of the
  recipients
