Choline, a dietary compound present in many foods, has recently
been classified as an essential nutrient for humans. There is evidence
from animal models that the availability of choline during the prenatal
period influences neural and cognitive development. Here we report that
choline supplementation during a 6 d gestational period protects
against neurodegeneration in the posterior cingulate and retrosplenial
cortices of female adolescent rats produced by peripheral
administration of the NMDA receptor antagonist dizocilpine (MK-801).
These data show that availability of a single nutrient, choline, during
a brief period of prenatal development diminishes vulnerability to
neurotoxicity in adolescent offspring.
Key words:
choline; neurotoxicity; cingulate; NMDA; MK-801; supplementation
