eLife Assessment
This study presents a valuable finding that depletion of the rRNA methyltransferase METTL5 enhances anti-tumor immunity through a novel mechanism involving neoantigen generation from non-canonical translation. The evidence supporting the central conclusions is solid, with comprehensive multi-omics data including ribosome profiling, immunopeptidomics, TCR sequencing, and multiple in vivo tumor models demonstrating synergy with immune checkpoint blockade.
