The novel GlcNH2-containing oligosaccharide Galα1-6GlcNH2 (designated melibiosamine; MelNH2) is expected to be immunosuppressive also. In Jurkat cells (immortalized human T lymphocytes), interleukin 2 (IL-2) production (an index of the T-cell immune response) can be induced by stimulation with a mitogen, such as concanavalin A. Here, we compared the effects of GlcNH2 and MelNH2 on concanavalin A-induced IL-2 production (CIIP) in Jurkat cells and found that GlcNH2 and MelNH2 at millimolar levels both significantly suppressed CIIP without affecting cell viability. When we examined the effects of GlcNH2 and MelNH2 on the activation of the three transcription factors required for CIIP—NFAT (nuclear factor of activated T-cells), NFκB (nuclear factor kappa-light-chain-enhancer of activated B cells), and AP-1 (activator protein 1)—we found that GlcNH2 and MelNH2 both suppressed CIIP by inhibiting the activation of NFAT and NFκB, but, unlike GlcNH2, MelNH2 also promoted the activation of AP-1. These results suggest that MelNH2 may be a potentially useful lead compound for development as an immunosuppressive or anti-inflammatory drug.","is_dataset_classified":null,"base_score":2.0794415416798357,"endowment":2.0794415416798357,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"31431927","pmcid":"PMC6580327","openalex_id":"https://openalex.org/W2949877890","authors":[],"funders":[{"funder_name":"KAKENHI","grant_id":"26640106","title":null},{"funder_name":"KAKENHI","grant_id":"15K07964","title":null},{"funder_name":"Japan Society for the Promotion of Science","grant_id":"","title":null}],"total_grants":3,"fwci":0.5309,"citation_percentile":0.62551812,"influential_citations":0,"citation_trend":[{"year":2020,"count":1},{"year":2021,"count":6}],"oa_status":"gold","license":"cc-by-nc-nd","oa_locations":[{"url":"https://www.sciencedirect.com/science/article/pii/S240558081930024X/pdf","host_type":"journal"},{"url":"https://www.sciencedirect.com/science/article/pii/S240558081930024X/pdf","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S240558081930024X?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S240558081930024X?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.bbrep.2019.100658","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/31431927","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/6580327","host_type":"repository"},{"url":"https://doaj.org/article/2c058c87d1b34e2d9e9f0fdfef530ae3","host_type":"repository"},{"url":"https://europepmc.org/articles/PMC6580327","host_type":"Europe_PMC"},{"url":"https://europepmc.org/articles/PMC6580327?pdf=render","host_type":"Europe_PMC"}],"fields_of_study":["Signaling Pathways in Disease","Research on Leishmaniasis Studies","Quinazolinone synthesis and applications"],"mesh_terms":[],"keywords":["Jurkat cells","NFAT","Oligosaccharide","Chemistry","Cell biology","NF-κB","Mitogen-activated protein kinase","Kinase","Molecular biology","T cell","Biology","Signal transduction","Biochemistry","Immunology","Gene","Transcription factor","Immune system","Interleukin 2","Jurkat cell","Glucosamine","Il-2, Interleukin-2","Immunosuppressive Drug","Pma, Phorbol 12-Myristate 13-Acetate","Ap-1, Activator Protein 1","Nfκb, Nuclear Factor Kappa-light-chain-enhancer Of Activated B Cells","Nfat, Nuclear Factor Of Activated T-cells","Cona, Concanavalin A","Melnh2, Melibiosamine","Piip, Pma/im-induced Il-2 Production","Ciip, Cona-induced Il-2 Production","Glcnh2, Glucosamine","Im, Ionomycin","Csa, Cyclosporine A","Melibiosamine"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-18T21:36:58.767366Z","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":[]}
