Oncolytic virotherapy is the use of replication-competent viruses to treat malignancies. The potential of oncolytic virotherapy as an approach to cancer therapy is based on historical evidence that certain viral infections can cause spontaneous remission of both hematologic and solid tumor malignancies. Oncolytic virotherapy may eliminate cancer cells through either direct oncolysis of infected...

The field of oncolytic virology has made great strides in recent years. However, one key finding has been that the use of viral agents that replicate selectively in tumors is usually insufficient to achieve anything beyond small and transient responses. Instead, like most cancer therapies, oncolytic viruses are most effective in combination with other therapies, which is where they have proven ...

Vaccines have classically been used for disease prevention. Modern clinical vaccines are continuously being developed for both traditional use as well as for new applications. Typically thought of in terms of infectious disease control, vaccination approaches can alternatively be adapted as a cancer therapy. Vaccines targeting cancer antigens can be used to induce anti-tumour immunity and have ...

The optimal route for clinical delivery of oncolytic viruses is thought to be systemic intravenous injection; however, the immune system is armed with several highly efficient mechanisms to remove pathogens from the circulatory system. To overcome the challenges faced in trying to delivery oncolytic viruses specifically to tumors via the bloodstream, carrier cells have been investigated to dete...

Background Oncolytic viruses are a promising approach for cancer therapy. Recent clinical trials proved the safety and antitumor activity of several oncolytic viruses in solid tumors. However, very little is known about the potential of the oncolytic viruses to target hematologic malignancies. Careful analysis of the effects of the oncolytic viruses in patients with hematologic malignancies wil...

Oncolytic viruses have demonstrated selective replication and killing of tumor cells. Different types of oncolytic viruses - adenoviruses, alphaviruses, herpes simplex viruses, Newcastle disease viruses, rhabdoviruses, Coxsackie viruses, and vaccinia viruses - have been applied as either naturally occurring or engineered vectors. Numerous studies in animal-tumor models have demonstrated substan...

Aptazymes are small, ligand-dependent self-cleaving ribozymes that function independently of transcription factors and can be customized for induction by various small molecules. Here, we introduce these artificial riboswitches for regulation of DNA and RNA viruses. We hypothesize that they represent universally applicable tools for studying viral gene functions and for applications as a safety...

Submit Manuscript | http://medcraveonline.com only recently that clinical trials demonstrated the effectiveness of OVs in humans with recent US Food and Drug Administration (FDA) approval of an oncolytic virus in advanced melanoma [2]. Oncolytic viruses open a new era in cancer treatment. This short article provides a comprehensive overview of Oncolytic viruses, their use as cancer therapeutic ...

In this paper, we have proposed and 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.
