Genetically Modified Mice as Tools to Understand the Neurobiological Substrates of Depression
Authors: Patricia Robledo, Elena Martín-Garcia, Ester Aso and Rafael MaldonadoThe pathophysiological mechanisms underlying depression are still poorly understood. An initial hypothesis postulated to explain the substrates of depression was based on the involvement of monoaminergic systems. This early theory was proposed from different findings obtained using pharmacological tools and can explain the mechanism of action of the drugs currently used to treat depression. However, more recent Read More

Transcriptional Dys-regulation in Anxiety and Major Depression: 5-HT1A Gene Promoter Architecture as a Therapeutic Opportunity
Authors: Paul R. Albert and Laura M. FioriThe etiology of major depression remains unclear, but reduced activity of the serotonin (5-HT) system remains implicated and treatments that increase 5-HT neurotransmission can ameliorate depressive symptoms. 5-HT1A receptors are critical regulators of the 5- HT system. They are expressed as both presynaptic autoreceptors that negatively regulate 5-HT neurons, and as post-synaptic heteroreceptors on non-serot Read More

Serotonin 5-HT4 Receptors: A New Strategy for Developing Fast Acting Antidepressants?
The regulation of the activity of brain monoaminergic systems has been the focus of attention of many studies since the first antidepressant drug emerged 50 years ago. The search for novel antidepressants is deeply linked to the search for fast-acting strategies, taking into account that 2-4 weeks of treatment with classical antidepressant are required before clinical remission of the symptoms becomes evident. In the recent Read More

Neurogenesis as a New Target for the Development of Antidepressant Drugs
Authors: Jesus Pascual-Brazo, Veerle Baekelandt and Juan Manuel EncinasThirteen years have passed since the neurogenic hypothesis of depression was postulated. One of its aspects, that decreased neurogenesis could be causative of the onset of depression has been difficult to prove. Another aspect, the prediction that increasing neurogenesis would not only be supportive but also required to produce clinical results by antidepressants has gathered experimental validation. Thus a question arises: Read More

Signaling Pathways Involved in Antidepressant-Induced Cell Proliferation and Synaptic Plasticity
In the last years it has been proposed that the antidepressant action is mediated not only by changes in monoamine levels but also in association with modifications involving cell proliferation and plasticity in some brain limbic areas as hippocampus, and also frontal cortex and amygdala. This leads to the merging of the classic “monoaminergic hypothesis of depression”, with the newer “neurotrophic hypothesis of depression”. Read More

Endocannabinoid Signaling in the Etiology and Treatment of Major Depressive Illness
Authors: Cecilia J. Hillard and Qing-song LiuThe purpose of this review is to examine human and preclinical data that are relevant to the following hypotheses. The first hypothesis is that deficient CB1R-mediated signaling results in symptoms that mimic those seen in depression. The second hypothesis is that activation of CB1R-mediated signaling results in behavioral, endocrine and other effects that are similar to those produced by currently used antidepressan Read More

Oxidative/Nitrosative Stress and Immuno-inflammatory Pathways in Depression: Treatment Implications
Authors: George Anderson and Michael MaesThis paper reviews recent work on the biological underpinnings of clinical depression emphasizing the crucial role of immunoinflammatory and oxidative and nitrosative stress (O&NS) pathways in driving changes in neuronal regulating tryptophan catabolites (TRYCATs). The essence of the association of O&NS pathways with autoimmune responses in depression is via damage to lipid membranes, anchorage molecules and f Read More

Novel Therapeutic Strategies in Major Depression: Focus on RNAi and Ketamine
Authors: Analia Bortolozzi, Pau Celada and Francesc ArtigasMajor depression is a severe psychiatric syndrome with very high prevalence and - socioeconomic impact. Despite extensive research, its pathophysiology is poorly understood, yet several neurotransmitter systems and brain areas have been implicated. The pharmacological treatment of major depression is mainly based on drugs inhibiting serotonin (5-hydroxytryptamine, 5-HT) and/or noradrenaline (NA) reuptake. Thes Read More
