IL-4 mediated TAP2 downregulation is a dominant and reversible mechanism of immune evasion and immunotherapy resistance in non-small cell lung cancer
Ranjan K, Rajendran B, Deen I, Costantini A, de Rodas M, Desai S, Scallo F, Gianino N, Ferrone S, Schalper K. IL-4 mediated TAP2 downregulation is a dominant and reversible mechanism of immune evasion and immunotherapy resistance in non-small cell lung cancer. Molecular Cancer 2025, 24: 80. PMID: 40091029, PMCID: PMC11912681, DOI: 10.1186/s12943-025-02276-z.Peer-Reviewed Original ResearchThis study investigates IL-4's role in TAP2 downregulation as a reversible mechanism of immune evasion and resistance to immunotherapy in non-small cell lung cancer, highlighting potential therapeutic strategies to restore TAP2 expression and enhance treatment efficacy.A Phase 1/1B Trial of Pembrolizumab and Trametinib in Advanced NSCLC Enriched for KRAS Mutations
