A 5-day conditioned place preference (CPP) paradigm was used. Nicotine (0.5 mg/kg; s.c.) induced a significant CPP, without any effect on the locomotor activity during the testing phase. TCS-OX2-29 (0.4, 0.8 and 4 μg/rat), as a selective OX2 receptor antagonist and AM251 (0.2, 1 and 2 μg/rat), as a selective cannabinoid CB1 receptor antagonist, individually or simultaneously were microinjected bilaterally into the VTA. The results showed that administration of AM251 (1 and 2 μg/rat) or TCS-OX2-29 (0.4, 0.8 and 4 μg/rat) into the VTA, during the 3-day conditioning phase or testing day, could dose-dependently inhibit the development of nicotine-induced CPP, in the acquisition or expression, respectively. Concurrent administration of ineffective doses of TCS-OX2-29 and AM251 into the VTA could not affect conditioning scores. The findings of this study support the possible role of OX2 and CB1 receptors in the VTA, in the acquisition and the expression of nicotine-induced place preference. Furthermore, our data suggest that there is a possible interaction between the VTA orexinergic and cannabinoid systems in nicotine-induced place preference.","is_dataset_classified":null,"base_score":2.9444389791664403,"endowment":2.9444389791664403,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"30017709","pmcid":null,"openalex_id":"https://openalex.org/W2883048670","authors":[],"funders":[{"funder_name":"Isfahan University of Medical Sciences, Isfahan, Iran","grant_id":"395466","title":null}],"total_grants":1,"fwci":0.764,"citation_percentile":0.68047997,"influential_citations":0,"citation_trend":[{"year":2018,"count":2},{"year":2019,"count":2},{"year":2020,"count":1},{"year":2021,"count":2},{"year":2022,"count":3},{"year":2023,"count":1},{"year":2024,"count":3},{"year":2026,"count":4}],"oa_status":"closed","license":"https://www.elsevier.com/tdm/userlicense/1.0/","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0304394018304865?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0304394018304865?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.neulet.2018.07.017","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/30017709","host_type":"repository"}],"fields_of_study":["Sleep and Wakefulness Research","Cannabis and Cannabinoid Research","Regulation of Appetite and Obesity","Animals","Conditioning, Operant","Dose-Response Relationship, Drug","Male","Microinjections","Nicotine","Orexin Receptor Antagonists","Orexin Receptors","Piperidines","Pyrazoles","Rats","Rats, Wistar","Receptor, Cannabinoid, CB1","Ventral Tegmental Area"],"mesh_terms":["Orexin Receptor Antagonists","Animals","Conditioning, Operant","Dose-Response Relationship, Drug","Male","Microinjections","Nicotine","Piperidines","Pyrazoles","Rats, Wistar","Ventral Tegmental Area","Receptor, Cannabinoid, CB1","Rats","Orexin Receptors"],"keywords":["AM251","Ventral tegmental area","Conditioned place preference","Cannabinoid receptor","Nicotine","Orexin","Orexin receptor","Pharmacology","Antagonist","Endocannabinoid system","Cannabinoid","Chemistry","Receptor","Medicine","Endocrinology","Internal medicine","Dopamine","Neuropeptide","Cannabinoid receptors","Orexin Receptors","Condition Place Preference"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-11T11:49:09.987049Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
