title: Expression of highly polysialylated neural cell adhesion molecule in rat subventricular zone with exposure to repeated kindled seizures.
abstract: Immunoreactive highly polysialylated neural cell adhesion molecule (PSA-NCAM) expression was examined in the rat with repeated exposure to amygdaloid kindled generalized seizures (GS). In the sham control brain, PSA-NCAM staining was slightly observed in the subventricular zone (SVZ) of the striatum. The number of PSA-NCAM positive cells increased four times in the bilateral SVZ after three consecutive GS, with a further increase after 30 consecutive GS. As PSA-NCAM is involved in neural plasticity as well as migration of neural stem cells (NSC), expression of PSA-NCAM in the SVZ suggests that the recurrent GS may mainly contribute to reconstruction of synaptic network and could also contribute to NSC migration after kindling.
