Cellular compartmentalization of phosphorylated eIF2alpha and neuronal NOS in human temporal lobe epilepsy with hippocampal sclerosis.

Hippocampal sclerosis (HS) is the most common neuropathologic finding in patients with medically refractory temporal lobe epilepsy (TLE). The mechanisms resulting in neuronal injury and cell loss in HS are incompletely understood, but inhibition of protein synthesis may play a pivotal role in these processes. This study examined the relationships between two molecules known to be involved in reduced protein synthesis in animals subjected to traumatic brain injury.
