Two months before a footpad injection of AdRL, rats had received AdRL injections into the right caudate. For each rat, brain areas showing upregulation of MHC I on microglial cells and infiltration of MHC I-positive round cells are marked as positive. Most of these areas also showed perivascular cuffing.
These rats, as part of a separate experiment, received a transection of the right optic nerve on day 7 after the footpad injection of AdRL.
