By triggering damage-associated molecular patterns, IRE activates dendritic cells (DCs) to prime systemic cytotoxic T lymphocyte (CTL) responses. However, IRE-activated CTLs predominantly accumulate in perivascular regions, limiting their infiltration into the tumor parenchyma. Oncolytic viruses (OVs) complement IRE by converting the \u201cprimed\u201d but spatially restricted CTL response into a robust, intratumoral immune attack. OVs secrete pro-inflammatory chemokines to chemoattract CTLs into the tumor core, while the non-thermal nature of IRE preserves antigen stability and vascular integrity, collectively sustaining DC activation and CTL infiltration. Moreover, intraoperative ultrasound-guided IRE not only establishes physical channels for precise OVs delivery but also enhances tumor cell susceptibility to OVs by disrupting membrane integrity. By bridging focal ablation with adaptive immunity, the synergistic effect\u2014IRE for systemic CTL priming and OVs for localized immune amplification\u2014transforms residual tumors into immunogenic niches, counteracting post-IRE recurrence through durable CTL-mediated clearance. The strategy leverages IRE\u2019s functional preservation and OVs\u2019 targeted lytic activity to synergistically enhance therapeutic efficacy while minimizing invasiveness.<\/jats:p>","DOI":"10.1136\/jitc-2024-009794","type":"journal-article","created":{"date-parts":[[2025,4,15]],"date-time":"2025-04-15T21:05:17Z","timestamp":1744751117000},"page":"e009794","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":15,"title":["Irreversible
