{"doi":"10.1128/jvi.00909-20","title":"Genetic Analyses of Contributions of Viral Interleukin-6 Interactions and Signaling to Human Herpesvirus 8 Productive Replication","abstract":"Human herpesvirus 8 (HHV-8)-encoded viral interleukin-6 (vIL-6) was the first viral IL-6 homologue to be identified. Experimental and clinical evidence suggests that vIL-6 is important for the onset and/or progression of HHV-8-associated endothelial-cell and B-cell pathologies, including AIDS-associated Kaposi's sarcoma and multicentric Castleman's disease. The protein is unusual in its poor secretion from cells and its intracellular activity; it interacts, directly or indirectly, with a number of proteins beyond the IL-6 signal transducer, gp130, and can mediate activities through these interactions in the endoplasmic reticulum. Here, we report the characterization with respect to protein interactions and signal-transducing activity of a panel of vIL-6 variants and utilization of HHV-8 mutant viruses expressing selected variants in phenotypic analyses. Our findings establish the importance of vIL-6 in HHV-8 productive replication and the contributions of individual vIL-6-protein interactions to HHV-8 lytic biology. This work furthers understanding of the biological significance of vIL-6 and its unique intracellular interactions.","journal":"Journal of Virology","year":2020,"id":108090,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":5,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.954,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2020-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":518132,"name":"Qiwang Xiang","orcid":"0009-0001-4710-7572","position":1,"is_corresponding":false},{"id":518133,"name":"Daming Chen","orcid":"0000-0001-9450-1145","position":2,"is_corresponding":false},{"id":518134,"name":"John Nicholas","orcid":"0000-0002-4058-9652","position":3,"is_corresponding":false},{"id":513097,"name":"Qian Li","orcid":"0000-0003-0359-5604","position":0,"is_corresponding":true}],"reference_count":51,"raw_metadata":null,"created_at":"2026-07-18T23:12:39.385256Z","pmid":"32669340","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":[]}
