Abstract
Herpes simplex virus type 1 (HSV-1) is a DNA virus and human pathogen used to construct promising therapeutic vectors. HSV-1 vectors fall into two classes: replication-selective oncolytic vectors for cancer therapy and defective non-replicative vectors for gene therapy. Vectors from each class can accommodate ≥30 kb of inserts, have been approved clinically, and demonstrate a relatively benign safety profile. Despite oncolytic HSV (oHSV) replication in tumors and elicited immune responses, the virus is well tolerated in cancer patients. Current non-replicative vectors elicit only limited immune responses. Seropositivity and immune responses against HSV-1 do not eliminate either the vector or infected cells, and the vectors can therefore be re-administered. In this review we highlight vectors that have been translated to the clinic and host-virus immune interactions that impact on the safety and efficacy of HSVs.
期刊介绍：
Trends in Molecular Medicine (TMM) aims to offer concise and contextualized perspectives on the latest research advancing biomedical science toward better diagnosis, treatment, and prevention of human diseases. It focuses on research at the intersection of basic biology and clinical research, covering new concepts in human biology and pathology with clear implications for diagnostics and therapy. TMM reviews bridge the gap between bench and bedside, discussing research from preclinical studies to patient-enrolled trials. The major themes include disease mechanisms, tools and technologies, diagnostics, and therapeutics, with a preference for articles relevant to multiple themes. TMM serves as a platform for discussion, pushing traditional boundaries and fostering collaboration between scientists and clinicians. The journal seeks to publish provocative and authoritative articles that are also accessible to a broad audience, inspiring new directions in molecular medicine to enhance human health.
