Abstract Major depressive disorder is a highly debilitating psychiatric involving the dysfunction of different cell types in brain. Microglia are predominant resident immune cells brain and exhibit critical role depression. Recent studies have suggested that depression can be regarded as microglial disease. regulate inflammation, synaptic plasticity, formation neural networks, all which affect In this review, we highlighted microglia pathology First, described activation animal models clinically depressed patients. Second, emphasized possible mechanisms by recognize depression-associated stress conditions. Third, how antidepressants (clinical medicines natural products) activation. Thus, review aimed to objectively analyze focus on potential antidepressants. These data regulation actions might novel therapeutic strategy counteract adverse effects devastating mental disorders.

This narrative review discusses how peripheral and central inflammation processes affect brain function structure in depression, reports on recent inflammatory marker-based functional structural magnetic resonance imaging (MRI) studies from the perspective of neural-circuit dysfunction depression. Chronic stress stimulates activity microglial cells, which increases production pro-inflammatory cytokines brain. In addition, activation promotes a shift synthesis serotonin to neurotoxic metabolites kynurenine pathway, induces glutamate-mediated excitotoxicity neurons. Furthermore, region specificity is hypothesized contribute vulnerability specific regions depression-related neural circuits inflammation-mediated injury. MRI are increasingly investigating blood levels markers such as C-reactive protein, interleukin (IL)-1β, IL-6, tumor necrosis factor-α associated with neuroimaging Functional have found that aberrant patterns altered connectivity involved emotion regulation, reward processing, cognitive control Structural suggested related reduced cortical gray matter subcortical volumes, thinning, decreased integrity white tracts within circuits.

Depression is a highly common mental disorder, which often multifactorial with sex, genetic, environmental, and/or psychological causes. Recent advancements in biomedical research have demonstrated clear correlation between gut dysbiosis (GD) or microbial and the development of anxiety depressive behaviors. The microbiome communicates brain through neural, immune, metabolic pathways, either directly (via vagal nerves) indirectly gut- microbial-derived metabolites as well hormones endocrine peptides, including peptide YY, pancreatic polypeptide, neuropeptide Y, cholecystokinin, corticotropin-releasing factor, glucagon-like peptide, oxytocin, ghrelin). Maintaining healthy microbiota (GM) now being recognized important for health use probiotics, prebiotics, synbiotics, fecal transplantation (FMT), etc. A few approaches exert antidepressant effects via restoring GM hypothalamus–pituitary–adrenal (HPA) axis functions. In this review, we summarized etiopathogenic link depression preclinical clinical evidence. addition, collated information on recent therapies supplements, such short-chain fatty acids, vitamin B12, omega-3 etc., target gut–brain (GBA) effective management behavior anxiety.

Depression is considered a major public health concern, where existing pharmacological treatments are not equally effective across all patients. The pathogenesis of depression involves the interaction complex biological components, such as immune system and microbiota‐gut‐brain axis. Adjunctive lifestyle‐oriented approaches for depression, including physical exercise special diets promising therapeutic options when combined with traditional antidepressants. However, mechanisms action these strategies incompletely understood. Accumulating evidence suggests that specific dietary regimens can modulate both gut microbiota composition. Here, we review current information about to alleviate their crosstalk inflammatory microbiome. We further discuss role axis possible mediator adjunctive therapies through mechanisms. Finally, future manipulate potential use exercise, interventions, prebiotics/probiotics, fecal transplantation.

The gut microbiota is a complex and dynamic ecosystem essential for the proper functioning of organism, affecting health disease status individuals. There continuous bidirectional communication between host, conforming to unique entity known as “holobiont”. Among these crosstalk mechanisms, synthesizes broad spectrum bioactive compounds or metabolites which exert pleiotropic effects on human organism. Many microbial can cross blood–brain barrier (BBB) have significant brain, playing key role in so-called microbiota-gut-brain axis. An altered (MGB) axis major characteristic many neuropsychiatric disorders, including depressive disorder (MDD). Significative differences eubiosis dysbiosis mental disorders like MDD with their different metabolite composition concentrations are being discussed. In present review, main (short-chain fatty acids -SCFAs-, bile acids, amino tryptophan -trp- derivatives, more), signaling pathways functions will be summarized explain part pathophysiology.
