Conditional IL4I1 inactivation triggers tumor-associated macrophage reprogramming and CD8+ T cell reactivation. Cancer Immunol Res. CIR-24-1159. 2026.PMID: 41537775
- This study uncovered a key role for IL4I1 in maintaining an immunosuppressive tumor microenvironment. We showed that targeting IL4I1 in macrophages restores antitumor immune responses through coordinated effects on tumor-associated macrophages and CD8⁺ T cells, highlighting its potential as a novel immunotherapy target.

An in vivo CRISPR screen unveils promising target genes to improve CAR-T cell efficacy in a solid tumor model. Mol Ther. S1525-0016(26)00274-1. 2026.
- Through a focused competitive CRISPR knockout screen in a human lung tumor model, we compared the relative efficacy of 50 gene targets proposed to enhance CAR-T cell persistence in vivo. Our screen identified some genes (ZC3H12A, SOCS1, PTPN2, and CDKN2A) as the most robust targets in this solid-tumor setting. Surprisingly, other gene edits (MED12) exhibited pro-, neutral, or anti-proliferative effects depending on the tumor context, demonstrating that the impact of gene editing on CAR-T cell persistence is highly context-dependent.

- Our review synthesizes emerging evidence that the spatial and functional organization of macrophage–T cell niches is a major determinant of antitumor immunity. It outlines how deciphering these immune ecosystems may reveal new biomarkers and therapeutic strategies to improve cancer immunotherapy.
