The study delved into how the D1-like dopamine receptors (D1Rs) and μ-opioid receptors (MOR) interact in the NAc region in the context of formalin-induced pain. Rats received intra-accumbal various doses of morphine as an MOR agonist (5, 10, 25, and 50 mmol/0.5μl) and different doses of SKF38393 as a selective D1Rs agonist (1.5, 3, 6, and 12 mmol/0.5μl) in separate experimental groups, respectively. In the second stage, animals received different doses of SCH23390 as a selective D1Rs antagonist (1.5, 3, 6, and 12 mmol) before an effective dose of SKF38393 (6 mmol) and morphine (10 mmol). The rats were then given naloxone as an MOR antagonist (1.5, 5, and 15 mmol) before being given an effective dose of SKF38393 (6 mmol). In the formalin test, 50 µl formalin (2.5 %) was subcutaneously injected into the rat's hind paw to induce pain behavioral responses. The main findings indicated that the opioidergic and dopaminergic systems in the NAc region interact to create analgesic effects. The injection of morphine and SKF38393 into the NAc resulted in pain-relieving impacts. However, SCH23390 decreased the antinociceptive impacts of SKF38393 and morphine. Similarly, naloxone reduced the analgesic effects of SKF38393. The interactions between D1Rs and MOR can lead to synergistic effects. Therefore, using D1Rs agonists along with morphine can enhance the antinociceptive effect of morphine while reducing its side effects.</div></div>","PeriodicalId":20201,"journal":{"name":"Physiology & Behavior","volume":"295 ","pages":"Article 114894"},"PeriodicalIF":2.4,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143743456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pharmacological inhibition of fatty acid amide hydrolase (FAAH), which augments endocannabinoid signaling, has emerged as a promising approach to treating depression. The main purpose of this study is to asses the influence of FAAH inhibitor URB597 on inflammatory response and oxidative stress in chronic unpredictable stress (CUS)-induced depressive female and male rats and to explore the underlying molecular mechanisms. Chronically stressed animals showed long-term memory deficits, while URB597 improved memory only in stressed males. URB597 treatment enhanced levels of brain-derived neurotrophic factor (BDNF) in the hippocampus and mPFC of stressed female and male rats and increased phosphorylated calcium/calmodulin-dependent protein kinase II (pCaMKII) levels in the hippocampus and mPFC of CUS males. Additionally, increased phosphorylation of JAK2 and STAT3 in the hippocampus and mPFC of CUS male and female rats, was reduced following URB597 treatment. URB597 decreased the CUS-enhanced iNOS protein expression in the hippocampus and mPFC of both sexes. Furthermore, URB597 normalized CUS-induced reductions in Nrf2 and HO-1 levels in the mPFC of both sexes, with no changes in the hippocampus. Our findings suggest that URB597 may inhibit the CUS-induced neuroinflammatory response by suppressing the pro-inflammatory mediators and the activation of the JAK2/STAT3 signaling in the hippocampus and mPFC of both sexes. URB597 treatment contributed to synaptic plasticity in a sex-specific manner by upregulating brain CaMKII signaling in males. URB597 also exerts neuroprotective effects through region-specific antioxidant properties.

Orexin and orexinergic receptors, found in crucial brain areas involved in reward processing, may play a significant role in reward mechanisms and addiction. Studies have shown that physical exercise can be an effective non-pharmacological approach to controlling drug use but limited research explores its role as pre-conditioning to prevent dependency on narcotics. In this study, 48 male Wistar rats were assigned into six groups: exercise training+saline (EX-SA), exercise training+METH 1mg/kg (EX-METH1), exercise training + METH 2 mg/kg (EX-METH2), control+saline (CON), control+METH 1 mg/kg (CON-METH1), control+METH 2 mg/kg (CON-METH2). The pre-conditioning groups underwent forced wheel-running training (five days a week, at 65 % Vmax) for eight weeks. Following pre-conditioning with exercise training, the METH groups received intraperitoneal (IP) METH injections using the conditioned place preference (CPP) model. After the post-test, the animals were dissected, and hippocampal tissue was collected to measure orexin receptor1 (OXR1) expression levels. The results showed that long-term, moderate-intensity forced exercise pre-conditioning prevented METH-induced CPP. However, CPP was observed only in the EX-METH2 group, receiving a double dose of the drug. Molecular analysis also revealed a significant increase in OXR1 expression in the hippocampus following METH injections, while physical exercise caused suppression in OXR1 increment. Seemingly, prior exercise influences this pathway and effectively prevents conditioning to METH, probably through OXR1, indicating an adaptation in the mesolimbic reward pathway that helps protect against METH addiction.</div></div>","PeriodicalId":20201,"journal":{"name":"Physiology & Behavior","volume":"295 ","pages":"Article 114892"},"PeriodicalIF":2.4,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143743454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we investigated whether suppressing activity in rNST GABA neurons likewise affects behavioral taste responsivity. Using mice in which Cre was expressed under the control of the GAD65 promoter, we made bilateral rNST injections of a Cre-dependent AAV driving expression of the inhibitory DREADD, hM4Di. Subsequently, we assessed concentration-dependent licking responses to sucrose, quinine, and quinine mixed in 300 mM sucrose. Relative to intraperitoneal injections of saline, clozapine-N-oxide injections significantly increased licking to sucrose and decreased licking to quinine, regardless of whether it was presented alone or mixed in sucrose. Neither oromotor (inter-lick intervals) nor appetitive (number of trials) variables were affected. Consistent with these behavioral effects, the neuronal activity marker, Fos, was expressed in more NST, reticular formation, and parabrachial nucleus cells following clozapine-N-oxide injections. A final experiment compared effects of chemogenetic GABA inhibition on sucrose licking in food deprived versus fed mice. Inhibiting GABA neurons enhanced sucrose licking in both homeostatic states. However, the impact was more marked under the latter state in female mice, suggesting a sex difference in the impact of satiety signals on GABA rNST neurons.</div></div>","PeriodicalId":20201,"journal":{"name":"Physiology & Behavior","volume":"295 ","pages":"Article 114889"},"PeriodicalIF":2.4,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143693103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Social isolation has been shown to inhibit infanticidal behavior in some strain of mice. However, it is unclear if highly infanticidal male CB57BL6 mice can sensitize after repeated exposures to pups. The aim of this study was to determine whether repeated non-contact exposure to pups (to prevent immediate attack), with or without movement restriction and social isolation, can inhibit infanticidal behavior in male mice. We also investigated whether pup-directed aggression was associated with male-male aggression in a resident-intruder test. We found that repeated non-contact exposure to pups, in socially isolated males or in males with movement restraint, significantly reduced the incidence of aggression towards pups and increased the incidence of parental behavior. Social isolation or movement restraint alone had no significant effect. Finally, the frequency of pup-directed aggression was not associated with the levels of male-male aggression. This study shows that the experience of being exposed to newborns without contact with them can inhibit the highly driven impulsive-like attacking behavior towards pups and facilitate parental behavior. Our results suggest that aggressive behavior towards pups can be blocked in naïve male mice and that this behavior differs from male-male aggression.</div></div>","PeriodicalId":20201,"journal":{"name":"Physiology & Behavior","volume":"295 ","pages":"Article 114885"},"PeriodicalIF":2.4,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143693106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
