This research demonstrates a novel arenavirus-based immune therapy amplifying T cell responses in cancer, suggesting a new treatment avenue.

To develop an optimized arenavirus based on LCMV for enhanced anti-tumoral immune responses in cancer therapy.
Adapted LCMV strain WE for tumor tissues through multiple passaging in cancer cells.
Identified and confirmed mutations enhancing tumor cell tropism in vitro and in vivo.
Combined effective mutations to create an attenuated reassortant LCMV for testing.
Assessed anti-tumoral efficacy and immune response in various tumor models.
Several mutations were found to accelerate propagation in cancer cells.
Generated arenavirus strains showed strong anti-tumoral efficacy with minimal replication in healthy tissues.
Treatment resulted in significant expansion of tumor-specific T cells and enhancements in T cell responses.
Combination with BiTE and CAR-T cells led to synergistic anti-tumoral effects.

Lang et al. (2026) studied this question.
