The commonly used lipopolysaccharide (LPS)-induced depression models often evaluate depression-like behaviors in the acute phase after a single intraperitoneal injection of LPS, and are not suitable for examining long-term depression-like behaviors. To overcome this limitation, we developed a mice LPS model for elucidating the long-term pathophysiology of depression. Using the tail-suspension test, we show that a single intraperitoneal injection of a high dose (1.66 mg/kg) of LPS prolonged depression-like behavior to 14 days after LPS administration unlike 4 days after administration for the most commonly used LPS dose (0.83 mg/kg). Upon high-LPS dose administration, TNF-α levels in the cerebrospinal fluid were increased only on the first day after administration. Moreover, LPS-induced depression-like behavior on day 10 after LPS administration was prevented by imipramine or minocycline. Immunohistochemical analysis revealed reduced neurogenesis in the hippocampal dentate gyrus of LPS-treated mice on day 10 of LPS administration. The LPS model, in which a single intraperitoneal administration of LPS at a dose double of the standard dose used currently, exhibits depression-like behavior via reduced neurogenesis mediated by neuroinflammation, and should be useful for elucidating the long-term pathophysiology of depression and for studying antidepressant drugs.

Vitamin D binding protein (VDBP) is a potential biomarker of major depressive disorder (MDD). This study demonstrates for the first time that VDBP is highly expressed in core emotion-related brain regions of mice susceptible to chronic unpredictable mild stress (CUMS). Specifically, the overexpression of microglia (MG)-derived VDBP in the prelimbic leads to depression-like behavior and aggravates CUMS-induced depressive phenotypes in mice, whereas conditional knockout of MG-derived VDBP can reverse both neuronal damage and depression-like behaviors.

Chronic exposure to prenatal stress can impair neurogenesis and lead to irreversible cognitive and neuropsychiatric abnormalities in offspring. The retina is part of the nervous system; however, the impacts of prenatal stress on retinal neurogenesis and visual function remain unclear. This study examined how elevated prenatal glucocorticoid levels differentially affect retinal development in the offspring of pregnant mice exposed to chronic unpredictable mild stress (CUMS).

This study established an animal model of comorbid depression and insomnia by combining chronic unpredictable mild stress (CUMS) with sleep deprivation (SD). The pathogenesis of comorbid depression and insomnia may be associated with impaired AMPK/FOXO3a signaling, which mediates autophagy inhibition, leading to decreased pineal melatonin secretion. The findings revealed that CUMS + SD rats exhibited more pronounced depression-like behaviors, sleep disorders, increased central oxidative stress, and exacerbated neuroinflammation, accompanied by reduced levels of 5-hydroxytryptophan (5-HT) and melatonin in the pineal gland.

Polystyrene microplastics (PS-MPs) are widespread pollutants in aquatic environments that accumulate in various organs, including the brain, raising concerns about their neurotoxic effects. This study exposed zebrafish to environmentally relevant concentrations (25 and 250 μg/L) of PS-MPs for 40 days to investigate their impact on neurobehavior and underlying mechanisms. Results revealed that PS-MPs induced depression-like behaviors in zebrafish, characterized by reduced exploration, decreased locomotor activity, and altered social interaction.

Depression is underpinned by a complex pathogenesis that involves the hippocampus and dorsal raphe nucleus (DRN) of the central nervous system. Although electroacupuncture (EA) is proven to be safe and effective for alleviating depression symptoms and causes minimal side effects its underlying therapeutic mechanism remains unclear. In this study, we performed targeted metabolomics to identify metabolite alterations in the hippocampus and DRN of Wistar Kyoto (WKY) rats and elucidate the role and potential mechanism of action of EA.
