In conclusion, our data further support a role for P11 in depression-like states and suggest that this gene is controlled by epigenetic mechanisms that can be affected by antidepressant treatment.
Increased expression of the Vesicular Glutamate Transporter-1 (VGLUT1) in the prefrontal cortex correlates with differential vulnerability to chronic stress in various mouse strains: effects of fluoxetine and MK-801.
Overall, the results appear to sustain the importance of the FSL rats as an animal model of depression in view of the impairment of NPY genes and the ability of fluoxetine treatment to normalize NPY-related gene expression selectively in this strain.
The data support our hypothesis that the NPY system dysregulation constitutes one of the biological underpinnings of depression and that one common mechanism of action of antidepressive treatment modalities may be effects on NPY and its receptors.

The results of the present study suggest that TPH2 gene expression in the midbrain part of the DRN is implicated in depression and stress response, as well as in the antidepressant fluoxetine action.
Similar to mice treated with selective serotonin reuptake inhibitors (SSRIs), TREK1 knockout mice are resistant to depression-like behavior and have elevated serotonin levels leading to speculation that TREK1 inhibition may contribute to the therapeutic effects of SSRIs.
Furthermore, these data indicate that chronic celecoxib treatment reverse chronic unpredictable stress-induced depressive-like behavior might via reducing COX-2 enzyme in brain, and the selective COX-2 inhibitors could be developed as potential remedies for the management of depression.

The association between the IL-6 polymorphism and reduced risk of depressive symptoms confirms the role of the inflammatory response system in the pathophysiology of IFN-alpha-induced depression; in contrast, the effect of the 5-HTT gene was small and perhaps dependent on the status of the inflammatory response.

Increased synthesis of CRF in CeA amplified CRF and arginine vasopressin peptide concentration in the paraventricular nucleus of the hypothalamus, and decreased glucocorticoid negative feedback, both markers associated with the pathophysiology of depression.
