Oncolytic viral therapy: new horizons for cancer remedy in the 21st Century

Abstract

Oncolytic viral therapy has proven to be propitious that is making glorious inroads against the vicious claws of cancer. Oncolytic viruses (OVs) are modified to replicate in a selective manner in neoplastic cells. They crossprime antineoplastic immunity by directly obliterating infected cancerous cells to propel uninfected cancer cell annihilation. The aspiration of this arena is to generate oncolytic viruses that can be comfortably constructed, proficiently disseminated to targeted neoplastic sites, experience quick intra-tumoural dispersion, explicitly destroy tumor cells, prompt no collateral harm and represent no danger of transmission within the populace. In this review, an attempt has been made to briefly discuss about an array of virus modulations that are being sought after to optimize administration, intra-tumoural scattering and safety of OVs gleaned from various viruses. With ceaseless progression, OVs can potentially revolutionize the current paradigm of cancer therapy.
