A hormetic approach to understanding antidepressant effectiveness and the development of antidepressant tolerance - A conceptual view.
A theoretical framework is developed for understanding how adaptations to SSRIs that restore synaptic homeostasis may partially contribute to their hormetic effects and rodent models show that serotonin neurotransmission to specific forebrain regions is a necessary, but insufficient cause of depressive symptoms.
From Serotonin to Neuroplasticity: Evolvement of Theories for Major Depressive Disorder
The evidence challenging the monoamine hypothesis is summarized and proposed that the antidepressant efficacy of SSRIs is not derived from elevated monoamine (5-HT, noradrenaline (NE), or dopamine (DA) concentration or monoamine neurotransmission.

    Serotonin and the CNS - New Developments in Pharmacology and Therapeutics [Working Title]
  • 2021
For most cases of endogenous depression (major depression), the hypothesis of monoamine deficiency, despite a number of limitations it faces, is still considered the most acceptable explanation. The
Integrating the monoamine and cytokine hypotheses of depression: Is histamine the missing link?
A role for histamine is proposed as a potential unifying factor that links monoamines to cytokines and stress‐induced depression is focused on to provide an updated perspective of depressive illness research and thereby identify new potential targets for the treatment of major depressive disorder.
Serotonin 2A receptors are a stress response system: implications for post-traumatic stress disorder

It is proposed that stress, particularly stress related to danger and existential threats, increases the expression and function of 5-HT2A receptors and is argued that this is a neurobiological adaptation to promote learning and avoidance of danger in the future.
Serotonin Receptors and Depression
In this review, the working mechanism of VMAT pumps, the role of BDNF and serotonin receptors in serotonergic pathways and depression formation were emphasized.
Rapid-acting antidepressants: shared neuropharmacological mechanisms
Novel evidence of a specific brain state characterized by slow EEG oscillations and the activation of molecular pathways implicated in rapid-acting antidepressant actions is provided, encouraging the investigation of cortical excitation and the subsequent homeostatic increase of slow EEGscillations as a fundamental basis of rapid- acting antidepressant treatments.
Computational Analysis of Therapeutic Neuroadaptation to Chronic Antidepressant in a Model of the Monoaminergic Neurotransmitter and Stress Hormone Systems
A computational model of the monoaminergic neurotransmitter and stress-steroid systems that neuroadapts to chronic administration of combinations of antidepressant drugs and hormones by adjusting the strengths of its transmitter-system components (TSCs) found that therapeutic neuroadaptation to chronic SSRI is an overdetermined process that depends on multiple TSCs.


5-HT1A receptor function in major depressive disorder
Chronic Citalopram Administration Causes a Sustained Suppression of Serotonin Synthesis in the Mouse Forebrain
It is demonstrated that chronic citalopram administration causes a sustained suppression of serotonin synthesis in the mouse forebrain, and the regulation of 5-HT synthesis warrants consideration in efforts to develop novel antidepressant strategies.
Serotonin in panic and anxiety disorders
The neurobiology of depression—revisiting the serotonin hypothesis. I. Cellular and molecular mechanisms
An overview of current developments in the field of serotonin (5-HT) hypothesis of depression, with an emphasis on cellular and molecular mechanisms, and how their unravelling opens new perspectives for future research is provided.
Receptor sensitivity and the mechanism of action of antidepressant treatment. Implications for the etiology and therapy of depression.
The effects of long-term antidepressant treatment on biogenic amine metabolism and on various indexes of presynaptic and postsynaptic receptor function are evaluated to provide support for hypotheses of amine receptor abnormalities in depression and indicate the need for expanded studies ofAmine receptor function in patients.
