The field of ultrasound (US) has changed significantly from medical imaging and diagnosis to treatment strategies. US contrast agents or microbubbles (MB) are currently being used as potential carriers for chemodrugs, small molecules, nucleic acids, small interfering ribonucleic acid, proteins, adenoviruses, and oncolytic viruses. Oncolytic viruses can selectively replicate within and destroy a...

Many drugs have been developed and optimized for the treatment of cancer; however, it is difficult to completely cure cancer with anticancer drugs alone. Therefore, the development of new therapeutic technologies, in addition to new anticancer drugs, is necessary for more effective oncotherapy. Oncolytic viruses are one potential new anticancer strategy. Various oncolytic viruses have been deve...

background: oncolytic herpes simplex virus (ohsv) vectors lacking γ34.5 has demonstrated anticancer effects without affecting normal cells. therefore, they are considered as ideal templates to construct efficient vectors for tumor targeting and cancer gene therapy. herein, we reported construction of three single/dually-labeled recombinant hsv-1 vectors, which provide an opportunity to replace ...

Oncolytic virotherapy is the use of genetically engineered viruses that specifically target and destroy tumor cells via their cytolytic replication cycle. Viral-mediated tumor destruction is propagated through infection of nearby tumor cells by the newly released progeny. Each cycle should amplify the number of oncolytic viruses available for infection. Our understanding of the life cycles of c...

Viruses are commonly thought of as opportunistic organisms that hijack cellular machinery with the ultimate goal of replicating and causing destruction in the host. However, viruses are increasingly being explored as therapeutic agents for a variety of disorders and diseases, including cancers, due to their natural ability to spread to various cell types. Oncolytic viruses are replication-compe...

In this paper, we have analyzed a mathematical model for the study of interaction between tumor cells and oncolytic viruses. The model is analyzed using stability theory of differential equations. We gain some conditions for global stability of trivial and interior equilibrium point.

Oncolytic virotherapy, a new type of cancer therapy involving viruses with oncolytic and immunostimulatory potential, is based on tumor selective viral replication, resulting in a specific lysis of tumor cells. Effective tumor targeting of oncolytic viruses remains a major problem because only a fraction of systemically applied viruses can reach the tumor tissue. We describe for the first time ...

Oncolytic virus therapy is perhaps the next major breakthrough in cancer treatment following the success in immunotherapy using immune checkpoint inhibitors. Oncolytic viruses are defined as genetically engineered or naturally occurring viruses that selectively replicate in and kill cancer cells without harming the normal tissues. T-Vec (talimogene laherparepvec), a second-generation oncolytic ...

Tumour-specific replicating (oncolytic) viruses are novel anticancer agents, currently under intense investigation in preclinical studies and phase I-III clinical trials. Until recently, most studies have focused on the direct antitumour properties of these viruses. There is now an increasing body of evidence indicating that host immune responses may be critical to the efficacy of oncolytic vir...
