Connexin43 hemichannels (Cx43 HCs), one of important subunits of gap junction protein, is highly expressed in astrocytes. It has been demonstrated that Cx43 HCs is involved in synaptic plasticity and learning and memory. However, whether the role of Cx43 HCs in the prefrontal cortex (PFC), a key brain region mediating cognitive and executive functions including working memory, still remains unclear. Here, we investigate that the role of Cx43 HCs in working memory through pharmacological inhibition of Cx43 HCs in the PFC. Gap26, a specific hemichannels blocker for Cx43 HCs, was bilaterally infused into the prelimbic (PrL) area of the PFC and then spatial working memory was examined in delayed alternation task in T-maze. Furthermore, the effect of Gap26 on synaptic transmission of prefrontal pyramidal neurons was examined using whole-cell patch recording in slice containing PFC. The demonstrate that inhibition of prefrontal cortex Cx43 HCs impairs the working memory and excitatory synaptic transmission of PFC neurons, suggesting that Cx43 HCs in the PFC contributes to working memory and excitatory synaptic transmission of neurons in rats.","is_dataset_classified":null,"base_score":2.8903717578961645,"endowment":2.8903717578961645,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"34662549","pmcid":null,"openalex_id":"https://openalex.org/W3205394005","authors":[],"funders":[],"total_grants":0,"fwci":0.8142,"citation_percentile":0.70562424,"influential_citations":0,"citation_trend":[{"year":2022,"count":1},{"year":2023,"count":3},{"year":2024,"count":7},{"year":2025,"count":3},{"year":2026,"count":3}],"oa_status":"closed","license":"https://doi.org/10.15223/policy-004","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0024320521010365?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0024320521010365?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.lfs.2021.120049","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/34662549","host_type":"repository"}],"fields_of_study":["Connexins and lens biology","Nicotinic Acetylcholine Receptors Study","Neuroscience and Neuropharmacology Research","Animals","Astrocytes","Brain","Connexin 43","Connexins","Gap Junctions","Male","Memory, Short-Term","Neuronal Plasticity","Neurons","Patch-Clamp Techniques","Prefrontal Cortex","Pyramidal Cells","Rats","Rats, Sprague-Dawley","Spatial Memory","Synaptic Transmission"],"mesh_terms":["Animals","Astrocytes","Brain","Male","Memory, Short-Term","Synaptic Transmission","Neuronal Plasticity","Neurons","Rats, Sprague-Dawley","Prefrontal Cortex","Gap Junctions","Connexins","Pyramidal Cells","Connexin 43","Patch-Clamp Techniques","Rats","Spatial Memory"],"keywords":["Neuroscience","Prefrontal cortex","Working memory","Excitatory postsynaptic potential","Neurotransmission","Infralimbic cortex","Gap junction","Synaptic plasticity","Psychology","Biology","Medicine","Cognition","Inhibitory postsynaptic potential","Cell biology","Internal medicine","Gap junctions","EPSC","Cx43 Hcs","T- Maze"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Decent work and economic growth"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-18T21:41:02.622755Z","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":[]}
