OV-mediated tumor destruction is now recognized as a powerful means to assist in the development of anti-tumor immunity for two important reasons: (i) OVs, through the elicitation of an anti-viral response and the production of type I interferon, are potent stimulators of inflammation and can be armed with transgenes to further enhance anti-tumor immune responses; and (ii) lytic activity can promote the release of tumor-associated antigens (TAAs) and tumor neoantigens that function as in situ tumor-specific vaccines to elicit adaptive immunity. Oncolytic herpes simplex viruses (oHSVs) are among the most widely studied OVs for the treatment of solid malignancies, and Amgen's oHSV Imlygic for the treatment of melanoma is the only OV approved in major markets. Here we describe important biological features of HSV that make it an attractive OV, clinical experience with HSV-based vectors, and strategies to increase applicability to cancer treatment. A. Introduction Recent advances in cancer therapeutics include the use of tumor-specific lytic (oncolytic) viruses that both debulk tumors -reduce their size by eliminating cancer cells -and break down barriers to the induction of anti-tumor immunity. Oncolytic viruses have been derived from a wide variety of both DNA and RNA virus families, each having unique host ranges and replication mechanisms that make them attractive for attacking different tumor types. Oncolytic virusmediated destruction of tumor cells leads to the production of danger signals by infected cells, a process referred to as immunogenic cell death, and to the release and presentation by antigen presenting cells (APCs) of virus and tumor-derived antigens. Tumor antigenic peptides are created by either an accumulation of mutations in cellular proteins, re-emergence of fetal/testis proteins without complete host tolerance, or by misfolded proteins to create novel processed peptides (Coulie et al.,","journal":"Caister Academic Press eBooks","year":2020,"id":109155,"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":3,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9524,"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":394964,"name":"Justus B.
