What is the role of genes implied in neurogenesis in major depression?

The role of genes implicated in neurogenesis in major depression is multifaceted and critical to understanding the etiopathogenesis and potential treatment strategies for this complex disorder. Research has identified that the expression of genes such as NGF, BDNF, and REST is lower in depressed patients, suggesting their significant role in the development of depressive disorders, while the expression of the GDNF gene is higher in patients with depression, indicating a potential compensatory mechanism or a pathological alteration associated with the condition. This aligns with the broader understanding that major depression involves genetic, epigenetic, and environmental factors, with neurogenesis in the hippocampus playing a crucial role, albeit not solely sufficient for explaining the therapeutic action of antidepressants. The regulatory effect of the entorhinal cortex on hippocampal function and adult neurogenesis further underscores the complexity of neural circuitry impairments in depression. The novel hypothesis that sphingolipids, particularly ceramide, may regulate neurogenesis and the hypothalamic-pituitary-adrenal axis in depression, presents a new avenue for antidepressant targets. Epigenetic regulation of neurogenesis is emerging as a crucial factor, with imbalances in hippocampal neurogenesis linked to the behavioral and cognitive deficits observed in depression. The neurogenesis theory, while not fully explanatory on its own, complements the monoamine theory by highlighting the role of neurogenesis in regulating the HPA axis, inflammation, and cognitive functions, which are all implicated in the pathogenesis and recovery from major depressive disorder (MDD). Genetic factors, despite their complexity and the small effect sizes of individual variants, play significant roles in MDD, indicating the need for large-scale studies to unravel the genetic underpinnings of the disorder. The potential role of adult hippocampal neurogenesis in the pathophysiology of depression suggests that mood disorders might be conceptualized as 'stem cell disorders', indicating a fundamental loss of neuronal plasticity. The interconnected signaling network involving the HPA axis, neurotrophins, growth factors, miRNAs, proinflammatory cytokines, and gastrointestinal signaling peptides, all modulate neurogenesis and are implicated in the mood alterations characteristic of MDD. Finally, while the direct involvement of neurogenesis in the etiology of depression remains speculative, preclinical studies have highlighted the role of hippocampal neurogenesis in mediating the behavioral effects of antidepressants, suggesting a reevaluation of its role in MDD.Down regulation of lipid metabolism at non-alcoholic steatohepatitis model
