Cathelicidins have been identified in several fish species. In this study we have isolated cathelicidin from Atlantic cod (Gadus morhua) and identified the cleavage site from the cathelin propart. This is the first isolation of a cathelicidin from teleost fish. The mature cathelicidin was found to be a 67-residues peptide, highly cationic with a pI of 13. Reversed phase chromatographic fractions containing the purified peptide had pronounced antimicrobial activity and the activity of the mature peptide was confirmed using a synthetic peptide. We examined the expression of cathelicidin during cod larvae early development using real-time PCR and detected expression that varied in the course of the first 68 days post hatching (dph). Two groups of larvae having a different food regime were compared. Cathelicidin expression was found to differ between the two groups and this could be linked to their food input. The presence and rapid adjustment of cathelicidin expression in the larvae indicate that the immune system of cod is active from early on in development and responds to external stimuli by the production of antimicrobial peptides.","is_dataset_classified":null,"base_score":4.0943445622221,"endowment":4.0943445622221,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"20950641","pmcid":null,"openalex_id":"https://openalex.org/W2158548324","authors":[],"funders":[{"funder_name":"Swedish Research Council for Environment, Agricultural Sciences and Spatial Planning","grant_id":"unidentified","title":"unidentified"},{"funder_name":"The Icelandic Centre for Research (RANNIS)","grant_id":"","title":null},{"funder_name":"The Torsten and Ragnar Söderberg Foundations","grant_id":"","title":null},{"funder_name":"The R&amp;D Fund of Ministry of Fisheries in Iceland (AVS)","grant_id":"","title":null},{"funder_name":"The University of Iceland Research Fund","grant_id":"","title":null},{"funder_name":"The Swedish Research Council","grant_id":"","title":null}],"total_grants":6,"fwci":3.7478,"citation_percentile":0.92870568,"influential_citations":0,"citation_trend":[{"year":2012,"count":5},{"year":2013,"count":7},{"year":2014,"count":2},{"year":2015,"count":8},{"year":2016,"count":7},{"year":2017,"count":3},{"year":2018,"count":3},{"year":2019,"count":4},{"year":2021,"count":3},{"year":2022,"count":3},{"year":2023,"count":1},{"year":2024,"count":4},{"year":2025,"count":3},{"year":2026,"count":1}],"oa_status":"closed","license":"Elsevier TDM","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0145305X1000248X?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0145305X1000248X?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.dci.2010.10.002","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/20950641","host_type":"repository"},{"url":"https://dx.doi.org/10.1016/j.dci.2010.10.002","host_type":""}],"fields_of_study":["Antimicrobial Peptides and Activities","Aquaculture disease management and microbiota","Invertebrate Immune Response Mechanisms","0301 basic medicine","0303 health sciences","03 medical and health sciences","Amino Acid Sequence","Animals","Antimicrobial Cationic Peptides","Blotting, Western","Gadus morhua","Gene Expression","Gene Expression Profiling","Larva","Molecular Sequence Data","RNA, Messenger","Reverse Transcriptase Polymerase Chain Reaction","Cathelicidins"],"mesh_terms":["Amino Acid Sequence","Animals","Larva","Molecular Sequence Data","RNA, Messenger","Blotting, Western","Gene Expression","Reverse Transcriptase Polymerase Chain Reaction","Gene Expression Profiling","Antimicrobial Cationic Peptides","Gadus morhua","Cathelicidins"],"keywords":["Cathelicidin","Antimicrobial peptides","Gadus","Peptide","Biology","Innate immune system","Antimicrobial","Biochemistry","Microbiology","Fish <Actinopterygii>","Receptor","Fishery","Reverse Transcriptase Polymerase Chain Reaction","Gene Expression Profiling","Blotting, Western","Molecular Sequence Data","Gene Expression","Gadus morhua","Cathelicidins","Larva","Animals","Amino Acid Sequence","RNA, Messenger","Antimicrobial Cationic Peptides"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Life below water"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-28T11:16:22.731801Z","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":[]}
