Abstract

DEFICITS IN NEUROPLASTICITY ARE HYPOTHESIZED TO UNDERLIE THE PATHOPHYSIOLOGY OF MAJOR DEPRESSIVE DISORDER (MDD): the effectiveness of antidepressants is thought to be related to the normalization of disrupted synaptic transmission and neurogenesis. The cyclic adenosine monophosphate (cAMP) signaling cascade has received considerable attention for its role in neuroplasticity and MDD. However components of a closely related pathway, the cyclic guanosine monophosphate (cGMP) have been studied with much lower intensity, even though this signaling transduction cascade is also expressed in the brain and the activity of this pathway has been implicated in learning and memory processes. Cyclic GMP acts as a second messenger; it amplifies signals received at postsynaptic receptors and activates downstream effector molecules resulting in gene expression changes and neuronal responses. Phosphodiesterase (PDE) enzymes degrade cGMP into 5'GMP and therefore they are involved in the regulation of intracellular levels of cGMP. Here we review a growing body of evidence suggesting that the cGMP signaling cascade warrants further investigation for its involvement in MDD and antidepressant action.

The cGMP signaling pathway. Presynaptic (top) and postsynaptic (bottom) elements of the cGMP signaling cascade are represented. AMPAR = 2-amino-3-(5-methyl-3-oxo-1,2-oxal-4-yl)propanoic acid receptor; CaMK = calcium-calmodium-dependent kinase; cAMP = cyclic adenosine monophosphate; cGMP = cyclic guanosine monophosphate; CNG = cyclic nucleotide gated channels; NO = nitric oxide; nNO = neuronal NO; PDE = phosphodiesterase; PI3K/AKT/Gsk3 = phosphoinositide 3-kinase/protein kinase B (aka AKT)/glycogen synthase kinase 3; PKGI = cGMP dependent protein kinase I; PKGII = cGMP dependent protein kinase II; sGC = soluble guanylate cyclase; VASP = vasodilator-stimulated phosphoprotein.
