However, the function of the PACAP-PAC1 system within the PAG with regards to SSDRs has received little attention. To address this gap, we used transgenic PAC1^flox/flox mice to examine both conditional and unconditional defensive reactions. We performed conditional PAC1 gene deletion within the ventrolateral(vl)PAG of PAC1^flox/flox mice using an adeno-associated virus (AAV) coding for Cre recombinase. Following viral expression, we used a white noise fear conditioning preparation that produces both an unconditional activity burst to the onset of noise that is followed by conditional freezing. On Day 1, mice received five white noise foot-shock pairings, whereas on Day 2, they were exposed to white noise five times without shock and we scored the activity burst and freezing to the white noise. Following behavioral testing, histology for immunofluorescent analysis was conducted in order to identify PACAP positive cells and stress-induced <i>c-fos</i> activity respectively. We found that PAC1 deletion in vlPAG increased the unconditional activity burst response but disrupted conditional freezing. PAC1 deletion was accompanied by higher <i>c-fos</i> activity following the behavioral experiments. Furthermore, a significant portion of PACAP-EGFP positive cells showed overlapping expression with VGAT, indicating their association with inhibitory neurons.

Participants in the stress group experienced a long-lasting stress phase, namely the preparation for the first state examination for law students. The control group consisted of law students without particular stress exposure.

The latter was only assessed in a subsample (<i>n</i> = 196). No associations between the DEP-PGS and stress-related variables were found. However, for the NEU-PGS we found a significant GxE effect. Only in individuals experiencing academic stress a higher PGS for neuroticism predicted stronger increases of perceived stress levels until the exam.

The EPM and OFT have been used for decades but are often criticized by behavioral scientists. Years ago, two revised anxiety assays were designed to improve upon the “classic” tests by excluding the possibility to avoid or escape aversion. The 3-D radial arm maze (3DR) and the 3-D open field test (3Doft) utilize continual motivational conflict to better model anxiety; each consist of an open space connected to ambiguous paths toward uncertain escape. Despite their utility, the revised assays have not caught on. This could be because no study yet has directly compared classic and revised assays in the same animals. To remedy this, we contrasted behavior from a battery of assays (EPM, OFT, 3DR, 3Doft and a sociability test) in mice defined genetically by isogenic strain, or environmentally by postnatal experience. One major motivation for this work is to inform future studies by offering a transparent look at individual outcomes on these assays, as there is no one-size-fits-all test to assess rodent anxiety-like behavior. Findings suggest that classic assays may sufficiently characterize differences across genetically defined groups, but the revised 3DR may be advantageous for investigating more nuanced behavioral differences such as those stemming from environmental factors. Finally, exposure to multiple assays significantly affected sociability, highlighting concerns for designing and interpreting batteries of rodent behavioral tests.</p>","PeriodicalId":50426,"journal":{"name":"Genes Brain and Behavior","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2023-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gbb.12869","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49693514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
