Abstract:
<p> It is not the existence of depressive symptomology, but understanding the function and effect that should be central in how to best support patients. Even in cases of milder depression, phase-of-life issues, or adjustment-related depressive episodes, the myth of a magical pill, here an antidepressant, appeals to the human desire for cessation of whatever unpleasantness may be arising. As a collective, clinicians may be placating clients&rsquo; psychological defenses and natural desire to suppress or dissociate at the expense of allowing a soulful opportunity to work through and resolve cha

<p>The CNS monoaminergic systems are considered as the head engine regulating neuropsychiatric functions and personality. Transcription factor AP-2 is known to be essential for the development of the brainstem including the monoaminergic nuclei, and has the ability to regulate many genes in the monoaminergic systems. The ability of transcription factors to regulate specific gene expression, has lately made them hot candidates as drug targets.

<p>Eukaryotic gene transcription plays a regulatory role in mammalian developmental processes.

In the mammalian central nervous system, the transcription factor AP-2 family is one of the critical regulatory factors for neural gene expression and neuronal development. It has been shown that several genes in the monoaminergic systems have AP-2 binding sites in regulatory regions, suggesting a regulatory role of AP-2 also in the adult brain.

Abstract:
The etiology of clinical depression is unknown, but thought to be related to an impairment in brain transmission of monoamines. Depression is treated with antidepressant drugs which, regardless of classification, ultimately result in increased efficacy of aminergic transmission. Tricyclic antidepressants are known to inhibit the presynaptic uptake of amines. [3H]Imipramine, the prototype tricyclic antidepressant and a potential biological marker in depression, binds to both high- and a low-affinity sites in the brain.

Abstract:
Since the formulation of the monoaminergic hypotheses of depression, several investigations have established that the serotonin (5-HT) as well as the noradrenaline (NA) systems are altered by antidepressant treatments. In the last few years, several studies have indicated that interactions between these two systems might also be important in the mechanism of action of antidepressant drugs. We have thus undertaken: (1) to elucidate the nature of some interactions between the 5-HT and NA systems in the rat hippocampus using in vivo electrophysiology and in vitro superfusion techniques; and (2) t

In humans and other organisms, monoaminergic systems are crucial in neuronal function and behavior. The monoamine transporters (MATs), which can be found on the presynaptic plasma membrane of neurons in the central nervous system (CNS), are crucial in the regulation of neurotransmitter concentration in the synaptic cleft. As the duration and concentration of neurotransmitters in the cleft affect further downstream signaling responses, these proteins are important targets for both understanding neuronal physiology and compounds of interest.

The implication of central noradrenergic and serotonergic systems in the control of mood has been known for forty years.
