Mammillary body atrophy is present in a number of neurological conditions and recent clinical findings highlight the importance of these nuclei for memory. While most accounts of diencephalic amnesia emphasize the functional importance of the hippocampal projections to the mammillary bodies, the present study tested the importance of the other…

In multiple sclerosis, CD8 T-cells are thought play a key pathogenetic role, but mechanistic evidence from rodent models is limited. Here, we have tested the encephalitogenic potential of CD8 T-cells specific for the model antigen ovalbumin (OVA) sequestered in oligodendrocytes as a cytosolic molecule. We show that in these "ODC-OVA" mice, the…
