Regional heterogeneity of polyamine effects on the N-methyl-D-aspartate receptor in rat brain.


Polyamines have pronounced effects on N-methyl-D-aspartate (NMDA) receptors in vitro and may be important modulators of NMDA receptor activity in vivo. There is considerable regional heterogeneity in the effects of polyamines on [3H]MK-801 binding in rat brain sections. For example, spermidine enhances the binding of [3H]MK-801 to a much greater extent in… (More)
