The forced swim test (FST) is a behavioral test in rodents which was developed in 1978 by Porsolt and colleagues as a model for predicting the clinical efficacy of antidepressant drugs. A modified version of the FST added the classification of active behaviors into swimming and climbing, in order to facilitate the differentiation between serotonergic and noradrenergic classes of antidepressant drugs. The FST is now widely used in basic research and the pharmaceutical screening of potential antidepressant treatments. It is also one of the most commonly used tests to assess depressive-like behavior in animal models. Despite the simplicity and sensitivity of the FST procedure, important differences even in baseline immobility rates have been reported between different groups, which complicate the comparison of results across studies. In spite of several methodological papers and reviews published on the FST, the need still exists for clarification of factors which can influence the procedure. While most recent reviews have focused on antidepressant effects observed with the FST, this one considers the methodological aspects of the procedure, aiming to summarize issues beyond antidepressant action in the FST. The previously published literature is analyzed for factors which are known to influence animal behavior in the FST. These include biological factors, such as strain, age, body weight, gender and individual differences between animals; influence of preconditioning before the FST: handling, social isolation or enriched environment, food manipulations, various kinds of stress, endocrine manipulations and surgery; schedule and routes of treatment, dosage and type of the drugs as well as experimental design and laboratory environmental effects. Consideration of these factors in planning experiments may result in more consistent FST results.

Simvastatin ameliorates cognitive impairments via inhibition of oxidative stress‑induced apoptosis of hippocampal cells through the ERK/AKT signaling pathway in a rat model of senile dementia

Senile dementia is a degenerative disease of the nervous system associated with cognitive impairments, memory disorders, executive dysfunctions, cognitive decline and dementia. Previous reports suggested that simvastatin presents ameliorative effects in the progression of senile dementia. However, the mechanism underlying simvastatin‑mediated improvements of cognitive competence during the progression of senile dementia remains to be elucidated. In the present study, a potential mechanism underlying simvastatin activity in hippocampal cells, was investigated. Results of the present study demonstrated that simvastatin significantly improved cognitive impairments, memory competence, amyloid plaques, loss of neurons and synapses, neurofibrillary tangles and oxidative damage in experimental rats. Results of the present study demonstrated that administration of simvastatin regulates superoxide dismutase, reactive oxygen species, catalase and glutathione in oxidative stress processes in hippocampal cells. Apoptosis of hippocampal cells was suppressed by simvastatin treatment in rats with senile dementia. Notably, the administration of simvastatin inhibited activating transcription factor‑6‑mediated extracellular signal‑regulated kinase/AKT serine/threonine kinase (ERK/AKT) signaling pathway in hippocampal cells. Taken together, the preclinical results of the present study indicate that simvastatin is efficient in preventing memory lapse and inhibiting apoptosis of hippocampal cells via the ERK/AKT signaling pathway, which may in the future improve cognitive decline and dementia in patients.

“…Low levels of light at these wavelengths modulates the release of nitric oxide (NO) (Uozumi et al, 2010) and increases both cerebral oxygenation (Wang et al, 2017) and blood flow (Salgado et al, 2015). Besides these effects, transcranial PBM can stimulate neurogenesis (Tanaka et al, 2011) and provide neuroprotection via antioxidant, anti-neuroinflammatory, and anti-apoptotic activities (De Taboada et al, 2011; Hamblin, 2017; Lu et al, 2017; Salehpour et al, 2017; Salehpour et al, 2018a). In particular, it has been demonstrated that transcranial PBM is able to increase regional cerebral blood flow in MDD patients (Schiffer et al, 2009).…”

This study was aimed to evaluate the effects of near-infrared (NIR) photobiomodulation (PBM) combined with coenzyme Q10 (CoQ10) on depressive-like behavior, cerebral oxidative stress, inflammation, and apoptosis markers in mice. To induce a depressive-like model, mice were subjected to sub-chronic restraint stress for 5 consecutive days. NIR PBM (810 nm laser, 33.3 J/cm2) and/or CoQ10 (500 mg/kg/day, gavage) were administered for five days concomitantly with immobilization. Behavior was evaluated by the forced swim test (FST), tail suspension test (TST), and open field test (OFT). Mitochondrial membrane potential as well as oxidative stress, neuroinflammatory, and markers of apoptosis were evaluated in the prefrontal cortex (PFC) and hippocampus (HIP). The serum levels of pro-inflammatory cytokines, cortisol, and corticosterone were also measured. PBM or CoQ10, or the combination, ameliorated depressive-like behaviors induced by restraint stress as indicated by decreased immobility time in both the FST and TST. PBM and/or CoQ10 treatments decreased lipid peroxidation and enhanced total antioxidant capacity (TAC), GSH levels, GPx and SOD activities in both brain areas. The neuroinflammatory response in the HIP and PFC was suppressed, as indicated by decreased NF-kB, p38, and JNK levels in PBM and/or CoQ10 groups. Intrinsic apoptosis biomarkers, BAX, Bcl-2, cytochrome c release, and caspase-3 and −9, were also significantly down-regulated by both treatments. Furthermore, both treatments decreased the elevated serum levels of cortisol, corticosterone, TNF-, and IL-6 induced by restraint stress. Transcranial NIR PBM and CoQ10 therapies may be effective antidepressant strategies for the prevention of psychopathological and behavioral symptoms induced by stress.
