Accessory viral protein, V, of Newcastle Disease Virus binds dsRNA to facilitate immune evasion

The evolving landscape of oncolytic virus immunotherapy: combinatorial strategies and novel engineering approaches

Oncolytic viruses (OVs) are a promising class of cancer therapy, exploiting their abilities to selectively infect and kill cancer cells while stimulating antitumor immune responses. The current assessment explores the changing horizons of OV immunotherapy, focusing on recent advances in technology plans to improve OV projects and combined approaches to improve curative efficacy. We discuss how OVs induce direct oncolysis and promote the release of tumor-associated antigens, leading to the activation of both innate and adaptive immunity. Special attention shall be given to programs for arm OVs to express curative genes, modify the tumor microenvironment and overcome immunosuppression. Moreover, we assess the synergies of uniting OVs with other immunotherapeutic techniques, such as immune checkpoint inhibitors and cell therapy, to improve tolerant outcomes. The present assessment provides an understanding of the relevant declaration of the OV analysis, highlighting the main obstacles and the future directions for the development of other capable and targeted cancer immunotherapy.
