Abstract
Herpes simplex virus type 1 (HSV-1) is a DNA virus with strong replication capabilities, a large genomic payload (≥30 kb), and low toxicity, making it a prominent vector in cancer gene therapy. Clinically approved oncolytic HSV-1 (oHSV-1) variants, such as T-VEC and G47Δ, demonstrate safety and efficacy in localized tumors, but face challenges in treating metastatic disease. To address this issue, next-generation oHSV-1 designs focus on precision targeting and immune remodeling through the delivery of multiple exogenous genes. In this review, we provide an overview of the inherent characteristics of oHSV-1 as a gene delivery platform, focusing on its genetic modification strategies, safety challenges in clinical applications, and future directions to maximize its therapeutic potential.
期刊介绍：
Trends in Pharmacological Sciences (TIPS) is a monthly peer-reviewed reviews journal that focuses on a wide range of topics in pharmacology, pharmacy, pharmaceutics, and toxicology. Launched in 1979, TIPS publishes concise articles discussing the latest advancements in pharmacology and therapeutics research.
The journal encourages submissions that align with its core themes while also being open to articles on the biopharma regulatory landscape, science policy and regulation, and bioethics.
Each issue of TIPS provides a platform for experts to share their insights and perspectives on the most exciting developments in the field. Through rigorous peer review, the journal ensures the quality and reliability of published articles.
Authors are invited to contribute articles that contribute to the understanding of pharmacology and its applications in various domains. Whether it's exploring innovative drug therapies or discussing the ethical considerations of pharmaceutical research, TIPS provides a valuable resource for researchers, practitioners, and policymakers in the pharmacological sciences.
