Oncolytic viruses: advanced strategies in cancer therapy

Oncolytic viruses (OVs) represent a promising strategy in cancer immunotherapy, as they selectively infect and lyse tumor cells while simultaneously triggering robust antitumor immune responses. By inducing immunogenic cell death, OVs enhance tumor antigen presentation and initiate a systemic immune response, effectively transforming the tumor microenvironment from an immune-suppressive state to an immune-permissive state. In addition to exerting direct oncolytic effects, OVs modulate key tumor-associated biological processes, including tumor angiogenesis and extracellular matrix remodeling, disrupting tumor progression and metastasis. Notably, recent advances have highlighted the therapeutic potential of…
