Oncolytic viruses (OVs) are novel anticancer agents that combine direct cancer cell killing with the stimulation of antitumor immunity. In addition, OVs can be engineered to deliver biological therapeutics directly to tumors, offering unique opportunities to design multimodal anticancer strategies. Here, a case for arming OVs with bispecific T cell engagers (BiTEs) is put forward. BiTEs redirect the cytotoxicity of polyclonal T cells to target cells of choice, and have demonstrated efficacy against a number of hematological cancers. However, the success of BiTEs in the treatment of solid tumors appears more limited, at least in part due to: (i) poor delivery kinetics and penetration into tumors, and (ii) on-target off-tumor activity, leading to dose-limiting toxicities. Linking the production of BiTEs to OV replication provides an exciting means to restrict production to the tumor site, widen their therapeutic window, and synergize with direct oncolysis. This review summarizes progress thus far in the preclinical development of BiTE-armed OVs, and explores the possibility of cotargeting cancer cells and nontransformed stromal cells.

Immunotherapy is one of the research hotspots in colorectal cancer field in recent years. The colorectal cancer patients with mismatch repair-deficient (dMMR) or high microsatellite instability (MSI-H) are the primary beneficiaries of immunotherapy. However, the vast majority of colorectal cancers are mismatch repair proficient (pMMR) or microsatellite stability (MSS), and their immune microenvironment is characterized by "cold tumors" that are generally insensitive to single immunotherapy based on immune checkpoint inhibitors (ICIs).

Introduction: The current first-line therapy for nasopharyngeal carcinoma (NPC) is often associated with long-term complications. Oncolytic measles virus (MV) therapy offers a promising alternative to cancer therapy. This study aims to investigate the efficacy of MV in killing NPC cells in vitro, both with or without resistance to radiation and drug therapy.

Oncolytic viruses are emerging as promising cancer therapeutic agents, with several poxviruses, including vaccinia virus (VACV) and myxoma virus, showing significant potential in preclinical and clinical trials. Modified vaccinia virus Ankara (MVA), a laboratory-derived VACV strain approved by the FDA for mpox and smallpox vaccination, has been shown to be incapable of replicating in human cells unless zinc finger antiviral protein (ZAP) is repressed. Notably, ZAP deficiency is prevalent in various cancer types.

Traditional cancer vaccines containing a single or a few discrete tumor epitopes have failed in the clinic, possibly due to challenges in epitope selection, target downregulation, cancer cell heterogeneity, tumor microenvironment immunosuppression, or a lack of vaccine immunogenicity. Whole cancer cell or cancer membrane vaccines, which provide a rich source of antigens, are emerging as viable alternatives.
