Ischemia-related change of ceruloplasmin immunoreactivity in neurons and astrocytes in the gerbil hippocampus and dentate gyrus.

In the present study, we investigated the temporal and spatial alterations of ceruloplasmin immunoreactivity in the gerbil hippocampus and dentate gyrus after 5 min transient forebrain ischemia. In sham-operated animals, ceruloplasmin immunoreactivity in the hippocampal CA2/3 areas was higher than that of other areas. Ceruloplasmin immunoreactivity and its protein content significantly increased and were highest in the CA1 area 1 day after ischemia-reperfusion.
