Abstract
Long-term depression (LTD) of synaptic transmission can be induced by several mechanisms, one thought to involve Ca2+-dependent activation of postsynaptic nitric oxide (NO) synthase and subsequent diffusion of NO to the presynaptic terminal. We used the stable NO donor S-nitroso- N-acetylpenicillamine (SNAP) to study the NO-dependent form of LTD at Schaffer collateral-CA1 synapses in vitro. SNAP (100 μM) enhanced the induction of LTD via a cascade that was blocked by the N-methyl-d-aspartate receptor antagonist d-2-amino-5-phosphonopentanoic acid (50 μM), NO guanylyl cyclase inhibitor 1H-[1,2,4] oxadiazolo [4,3-a] quinoxalin-1-one (10 μM), and the PKG inhibitor KT5823 (1 μM). We further show that LTD induced by low-frequency stimulation in the absence of SNAP also is blocked by KT5823 or Rp-8-(4-chlorophenylthio)-guanosine 3′,5′-cyclic monophosphorothioate (10 μM), cyclic guanosine 3′,5′ monophosphate-dependent protein kinase (PKG) inhibitors with different mechanisms of action. Furthermore SNAP-facilitated LTD was blocked when release from intracellular calcium stores was inhibited by ryanodine (10 μM). Finally, two cell-permeant antagonists of the cyclic ADP-ribose binding site on ryanodine receptors also were able to block the induction of LTD. These results support a cascade for induction of homosynaptic, NO-dependent LTD involving activation of guanylyl cyclase, production of guanosine 3′,5′ cyclic monophosphate and subsequent PKG activation. This process has an additional requirement for release of Ca2+from ryanodine-sensitive stores, perhaps dependent on the second-messenger cyclic ADP ribose.
