This video demonstrates an ex vivo technique to induce brain cell death mediated through cytotoxic CD8+ T cells. Upon obtaining brain slices, activated oligodendrocyte-directed CD8+ T cells are transferred onto the slices to target the myelin sheath and oligodendrocytes. Post-incubation, the damage to myelin and neuronal death can be assessed histologically in the regions of interest.
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board.
