Alterations in colocalized agmatine and glutamate levels in the SR synaptic terminals, following 4 days Morris water maze training, were also investigated. Ninety-seven percent of all agmatinergic profiles were found to contain glutamate, and 92% of all glutamatergic profiles contained agmatine (n=6 300 terminals). Subcellular investigation, using postembedding electron microscopy-immunogold cytochemistry, has also revealed that agmatine is colocalized with glutamate in most synaptic terminals in the SR region of CA1. In the present study we demonstrate, using immunofluorescence confocal microscopy, that agmatine is colocalized with glutamate within CA1-CA3 hippocampal pyramidal cell bodies, in young Sprague-Dawley rats. Agmatine-immunoreactivity has been observed within synaptic terminals of asymmetric excitatory synapses in the hippocampal CA1 stratum radiatum (SR), suggesting that agmatine may be colocalized with glutamate. Recent studies have demonstrated that endogenous agmatine may directly participate in the processes of spatial learning and memory. Spatial learning-induced accumulation of agmatine and glutamate at hippocampal CA1 synaptic terminals.Īgmatine, the decarboxylated metabolite of l-arginine, is considered to be a novel putative neurotransmitter. ![]() ![]() Those genes that are highly expressed during the first year of postnatal life may influence and orchestrate the early development of cortical neural circuitry while genes portraying a pattern of increasing expression with age may indicate a role in DLPFC maturation and attainment of adult levels of cognitive function. Interestingly, dopamine D5 receptor mRNA levels negatively correlated with age (r = -0.31, p = 0.018) in an expression profile opposite to that of the dopamine D1 receptor.We find distinct developmental changes in key components of the dopamine system in DLPFC over postnatal life. Monoamine oxidase B mRNA and protein (p less than 0.001) levels also increased significantly throughout development. In contrast, dopamine D1 receptor mRNA correlated positively with age (p = 0.002) and dopamine D1 receptor protein expression increased throughout development (p less than 0.001) with adults having the highest D1 protein levels (p ≤ 0.01). Similarly, mRNA levels of dopamine receptors D2S (p less than 0.001) and D2L (p = 0.003) isoforms, monoamine oxidase A (p less than 0.001) and catechol-O-methyltransferase (p = 0.024) were significantly higher in neonates and infants as was catechol-O-methyltransferase protein (32 kDa, p = 0.027). Protein levels for tyrosine hydroxylase peaked during the first year of life (p less than 0.001) then gradually declined to adulthood. Protein expression was analysed by western blot. We assessed pre- and postsynaptic components of the dopamine system including tyrosine hydroxylase, the dopamine receptors (D1, D2 short and D2 long isoforms, D4, D5), catechol-O-methyltransferase, and monoamine oxidase (A and B) in the developing human DLPFC (6 weeks -50 years).Gene expression was first analysed by microarray and then by quantitative real-time PCR. Few studies have reported on the normal development of the dopamine system in human DLPFC during postnatal life. The dorsolateral prefrontal cortex (DLPFC) is critical for working memory which does not fully mature until the third decade of life.
