Litter reduction-induced obesity promotes early depressive-like behavior and elevated prefrontal cortex GFAP expression in male offspring
Behav Brain Res. 2023 Dec 26:114839. doi: 10.1016/j.bbr.2023.114839. Online ahead of print.ABSTRACTAIMS: The present study was developed to investigate how litter reduction-induced obesity promotes early depressive-related behaviors in rodent offspring.MAIN METHODS: We employed a standardized litter size reduction protocol, dividing litters into groups: normal litters (NL), consisting of six males and six females pups and small litters (SL), comprising two males and two females pups. Maternal behavior was monitored during the initial week of lactation. Subsequently, we assessed the pups for weight gain, locomotor activity,...

Differential expression of alpha-synuclein in the hippocampus of shr and sla16 isogenic rat strains
Behav Brain Res. 2023 Dec 25:114835. doi: 10.1016/j.bbr.2023.114835. Online ahead of print.ABSTRACTTwo inbred strains, Lewis (LEW) and Spontaneously Hypertensive Rats (SHR), are well-known for their contrasting behavior related to anxiety/emotionality. Studies with these two strains led to the discovery of the Quantitative Trait Loci (QTL) on chromosome 4 (Anxrr16). To better understand the influences of this genomic region, the congenic rat strain SLA16 (SHR.LEW-Anxrr16) was developed. SLA16 rats present higher hyperactivity/impulsivity, deficits in learning and memory, and lower basal blood pressure than the SHR strain, ...

CX3CR1 mediates Motor Dysfunction in Mice through 5-HTR2a
Behav Brain Res. 2023 Dec 23:114837. doi: 10.1016/j.bbr.2023.114837. Online ahead of print.ABSTRACTCX3CR1 knockout could induce motor dysfunction in several neurological disease models mainly through regulating microglia's function. While CX3CR1 was expressed on neurons in a few reports, whether neuronal CX3CR1 could affect the function of neurons and mediate motor dysfunction under physiological conditions is unknown. To elucidate the roles of neuronal CX3CR1 on motor dysfunction, CX3CR1 knockout mice were created. Rotarod test and Open field test found that the CX3CR1-/- mice's motor capacity was reduced. Immunofluoresce...

LPC20K modified from krill oil ameliorates the scopolamine-induced cognitive impairment
Behav Brain Res. 2023 Dec 23:114836. doi: 10.1016/j.bbr.2023.114836. Online ahead of print.ABSTRACTAlzheimer's disease (AD) is characterized by cognitive impairment. It is common in the elderly. Etiologically, dysfunction of cholinergic neurotransmitter system is prominent in AD. However, disease modifying drug for AD is still unavailable. We hypothesized that krill oil and modified krill oil containing 20% lysophosphatidylcholine-docosahexaenoic acid (LPC-DHA, LPC20K) could play a crucial role in AD by improving cognitive functions measured by several behavioral tests. We found that LPC20K could ameliorate short-term, lon...

Sex differences in the anticompulsive-like effect of memantine: involvement of nitric oxide pathway but not AMPA receptors
Behav Brain Res. 2023 Dec 22:114834. doi: 10.1016/j.bbr.2023.114834. Online ahead of print.ABSTRACTMemantine, an N-Methyl-D-Aspartate (NMDA) antagonist, has been examined as a potential treatment for Obsessive-Compulsive Disorder (OCD). Yet, there is limited knowledge regarding how it works to reduce compulsive behaviour and whether it has different effects on individuals based on their sex. Herein, we investigated if there are sex differences in the anticompulsive-like effect of memantine in adult Swiss mice. Additionally, we explored whether the nitric oxide (NO) pathway and α-amino-3-hydroxy-5-methyl-4-isoazolepropioni...

Copaifera langsdorffii Desf. tree oleoresin-induced antinociception recruits µ < sub > 1 < /sub > - and κ -opioid receptors in the ventrolateral columns of the periaqueductal grey matter
Behav Brain Res. 2023 Dec 22:114832. doi: 10.1016/j.bbr.2023.114832. Online ahead of print.ABSTRACTPopular medicine has been using oleoresin from several species of copaiba tree for the treatment of various diseases and its clinical administration potentially causes antinociception. Electrical stimulation of ventrolateral (vlPAG) and dorsolateral (dlPAG) columns of the periaqueductal gray matter also causes antinociception. The aim this study was to verify the antinociceptive effect of oleoresin extracted from Copaifera langsdorffii tree and to test the hypothesis that oleoresin-induced antinociception is mediated by µ1- ...

Long-term Impacts of Prenatal Maternal Immune Activation and Postnatal Maternal Separation on Maternal behavior in Adult Female Rats: Relevance to Postpartum Mental Disorders
Behav Brain Res. 2023 Dec 22:114831. doi: 10.1016/j.bbr.2023.114831. Online ahead of print.ABSTRACTEarly life adversities are known to exert long-term negative impacts on psychological and brain functions in adulthood. The present work examined how a prenatal brain insult and a postnatal stressor independently or interactively influence the quality of maternal care of postpartum female rats and their cognitive and emotional functions, as a way to identify the behavioral dysfunctions underlying childhood trauma-induced postpartum mental disorders (as indexed by impaired maternal care). Sprague-Dawley female offspring born f...

The role of serotonin in modulating social competence in a cooperatively breeding fish
Behav Brain Res. 2023 Dec 21:114819. doi: 10.1016/j.bbr.2023.114819. Online ahead of print.ABSTRACTBehavioural interactions between conspecifics rely on the appreciation of social cues, which is achieved through biochemical switching of pre-existing neurophysiological pathways. Serotonin is one of the major neurotransmitters in the central nervous system responsible for the modulation of physiological and behavioural traits, in particular social behaviour. The relative importance of serotonin in modulating optimal social responses to the available social information (i.e., social competence) is yet unknown. Here we investi...

Differential effect of chronic mild stress on anxiety and depressive-like behaviors in three strains of male and female laboratory mice
Behav Brain Res. 2023 Dec 21:114829. doi: 10.1016/j.bbr.2023.114829. Online ahead of print.ABSTRACTMajor depressive disorder is the most common psychiatric disorder worldwide. To understand mechanisms and search for new approaches to treating depression, animal models are crucial. Chronic mild stress (CMS) is the most used animal model of depression. Although CMS is considered a robust model of depression, conflicting results have been reported for emotion-related behaviors, which the intrinsic characteristics of each rodent strain could explain. To further shed light on the impact of genetic background on the relevant par...
