IFN-induced tryptophan (Trp) depletion in cancer cells triggers mistranslation, resulting in tryptophan-to-phenylalanine (W→F) substitutions. Using a CRISPR screen, this study identified ADAR1 and FTSJ1 as regulators of W→F mistranslation by maintaining expression of ribosome quality control (RQC) factors and tRNA^Trp methylation, respectively. Furthermore, the authors demonstrated HLA class I presentation and T-cell recognition of FTSJ1-dependent neoepitopes, revealing a regulatory mechanism of neoantigen generation independent of DNA mutations.

This study identified a melanoma-associated noncanonical antigen, EVA003, and demonstrated that its peptides are presented by HLA-A03:01 and recognized by patient-derived TILs. The authors identified a specific TCR and showed that transferring this TCR into healthy donor T cells enabled recognition and killing of melanoma cells. These findings suggest the potential of targeting noncanonical antigens with TCR-engineered T-cell therapy.

This study shows that migrasomes produced by circulating tumor cells can stimulate antitumor immunity. Migrasomes enriched in tumor antigens are taken up by antigen-presenting cells, which then cross-present migrasome-derived antigens to elicit tumor-specific CD8+ T cell responses, thereby suppressing metastasis.

This study shows how tumors evade recognition of mutant p53-derived neoantigens by T cells: poor processing, HLA allele loss, ERAP1-mediated degradation of I195F peptides, and weak R175H–HLA binding. Altering antigen presentation may overcome immune escape.

🎉 New paper in @CCR_AACR!
Congratulations to Ryoichi Maenosono (@r_maenosono) and the team!
🔬 Using 41-plex spatial imaging, we reveal how #TLS-like immune niches are associated with better outcomes in #BladderCancer
These TLS-like structures are not identifiable by HE staining.

Development of Universal Cell Embedding (UCE), a foundation model for single-cell analysis. By tokenizing genes using a protein language model (ESM2) and training a Transformer neural network, UCE enables zero-shot mapping of cells from unseen datasets and species into a universal latent space. The study constructed the Integrated Mega-scale Atlas (IMA) comprising 36 million cells using UCE, achieving a universal representation of all cell states and types.
