Delayed loss of striatal dopamine receptors during aging of dietarily restricted rats.


Dietary restriction by feeding every other day retards the normal age-associated loss of dopamine receptors from the corpus striatum of the rat. Ad libitum fed animals lose about 40% of the receptors labeled by [3H]spiperone between 3 and 24 months, while the loss is only about 20% over the same period in restricted rats. Ultimately, by 30 months of age… (More)
