{"doi":"10.17615/8ayb-vb89","title":"Syndecan-1 and syndecan-2 play key roles in herpes simplex virus type-1 infection","abstract":"Herpes simplex virus type 1 (HSV-1) is an important human pathogen and a leading cause of infectious blindness in the developed world. HSV-1 exploits heparan sulfate proteoglycans (HSPG) for attachment to cells. While the significance of heparan sulphate (HS) moieties in HSV-1 infection is well established, the role of specific proteoglycan core proteins in the infection process remains poorly understood. The objective of this study was to assess the roles of syndecan-1 and syndecan-2 core proteins in HSV-1 infection, both of which are expressed by many HSV-1 target cell types. Our results demonstrate that syndecan-1 and syndecan-2 gene silencing by RNA interference reduces HSV-1 entry, plaque formation and facilitates cell survival. Furthermore, HSV-1 infection increases syndecan-1 and syndecan-2 protein synthesis and a resultant increase in cell surface expression of HS. Our observations suggest that changes in syndecan-1 and syndecan-2 expression levels may be related to active viral infection. Taken together, our findings provide new insights into HSPG functions during HSV-1 entry and spread.","journal":"UNC Libraries","year":2020,"id":140351,"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":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9607,"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":486209,"name":"Tibor Vályi-Nagy","orcid":"0000-0003-1212-584X","position":1,"is_corresponding":false},{"id":605098,"name":"Sarolta Bacsa","orcid":null,"position":2,"is_corresponding":false},{"id":286249,"name":"Deepak Shukla","orcid":"0000-0002-3039-6953","position":3,"is_corresponding":false},{"id":288986,"name":"Jian Liu","orcid":"0000-0001-8552-1400","position":4,"is_corresponding":false},{"id":605099,"name":"Sándor Dósa","orcid":null,"position":5,"is_corresponding":false},{"id":605097,"name":"Ghadah A.
