Abstract

The mode and mechanism of neuronal death induced by status epilepticus (SE) in the immature brain have not been fully characterized. In this study, we analyzed the contribution of neuronal necrosis and caspase-3 activation to CA1 damage following lithium-pilocarpine SE in P14 rat pups. By electron microscopy, many CA1 neurons displayed evidence of early necrosis 6 hours following SE, and the full ultrastructural features of necrosis at 24-72 hours. Caspase-3 was activated in injured (acidophilic) neurons 24 hours following SE, raising the possibility that they died by caspase-dependent "programmed" necrosis.
