abstract：:Cathepsin D-like activity in homogenates of five brain areas of 3-month-old and 24-month-old Fischer 344 rats was measured. With hemoglobin as substrate at pH 3.2, more than 90% of the activity was inhibited by pepstatin. In each area studied, activity was more than twice as high in the old rat brain: 140-160% higher ...

abstract：:In the striatum, dopamine (DA) exerts a major modulatory influence on voltage- and ligand-gated currents. Previously we have shown that DA modulates glutamatergic neurotransmission and that the direction of this modulation depends on, among other factors, the glutamate and DA receptor subtypes activated. These effects...
