11), providing possible avenues for new vaccine and pharmaceutical development. Evans, R. Protein complex prediction with AlphaFold-Multimer. Science A to Z Puzzle. Just 4% of these instances contain complete chain pairing information (Fig. Chen, S. Y., Yue, T., Lei, Q. Zhang, S. Q.

Direct comparative analyses of 10× genomics chromium and Smart-Seq2.
Bioinformatics 39, btac732 (2022). About 97% of all antigens reported as binding a TCR are of viral origin, and a group of just 100 antigens makes up 70% of TCR–antigen pairs (Fig. Supervised predictive models. Critically, few models explicitly evaluate the performance of trained predictors on unseen epitopes using comparable data sets. New experimental and computational techniques that permit the integration of sequence, phenotypic, spatial and functional information and the multimodal analyses described earlier provide promising opportunities in this direction 75, 77. The development of recombinant antigen–MHC multimer assays 17 has proved transformative in the analysis of TCR–antigen specificity, enabling researchers to track and study T cell populations under various conditions and disease settings 18, 19, 20. One may also co-cluster unlabelled and labelled TCRs and assign the modal or most enriched epitope to all sequences that cluster together 51. These limitations have simultaneously provided the motivation for and the greatest barrier to computational methods for the prediction of TCR–antigen specificity. Pavlović, M. The immuneML ecosystem for machine learning analysis of adaptive immune receptor repertoires. Shakiba, M. TCR signal strength defines distinct mechanisms of T cell dysfunction and cancer evasion. Finally, developers should use the increasing volume of functionally annotated orphan TCR data to boost performance through transfer learning: a technique in which models are trained on a large volume of unlabelled or partially labelled data, and the patterns learnt from those data sets are used to inform a second predictive task.
Models that learn a mathematical function mapping from an input to a predicted label, given some data set containing both input data and associated labels. Luu, A. M., Leistico, J. R., Miller, T., Kim, S. & Song, J. 47, D339–D343 (2019). Nature 596, 583–589 (2021). Gilson, M. BindingDB in 2015: a public database for medicinal chemistry, computational chemistry and systems pharmacology. Chinery, L., Wahome, N., Moal, I. Paragraph — antibody paratope prediction using Graph Neural Networks with minimal feature vectors. Although there are many possible approaches to comparing SPM performance, among the most consistently used is the area under the receiver-operating characteristic curve (ROC-AUC). Considering the success of the critical assessment of protein structure prediction series 79, we encourage a similar approach to address the grand challenge of TCR specificity inference in the short term and ultimately to the prediction of integrated T and B cell immunogenicity. Bioinformatics 33, 2924–2929 (2017). Li, G. T cell antigen discovery via trogocytosis. TCRs may also bind different antigen–MHC complexes using alternative docking topologies 58. We encourage the continued publication of negative and positive TCR–epitope binding data to produce balanced data sets.
The other authors declare no competing interests. Marsh, S. IMGT/HLA Database — a sequence database for the human major histocompatibility complex. Answer for today is "wait for it'. Methods 403, 72–78 (2014). Our view is that, although T cell-independent predictors of immunogenicity have clear translational benefits, only after we can dissect the relative contribution of the three stages described earlier will we understand what determines antigen immunogenicity.
The former, and the focus of this article, is the prediction of binding between sets of TCRs and antigen–MHC complexes. Dean, J. Annotation of pseudogenic gene segments by massively parallel sequencing of rearranged lymphocyte receptor loci. BMC Bioinformatics 22, 422 (2021). Science 376, 880–884 (2022). Cell Rep. 19, 569 (2017). Peer review information. It is now evident that the underlying immunological correlates of T cell interaction with their cognate ligands are highly variable and only partially understood, with critical consequences for model design.

TOX is a critical regulator of tumour-specific T cell differentiation.
Therefore, thoughtful approaches to data consolidation, noise correction, processing and annotation are likely to be crucial in advancing state-of-the-art predictive models. Cell 178, 1016 (2019). Chen, G. Sequence and structural analyses reveal distinct and highly diverse human CD8+ TCR repertoires to immunodominant viral antigens. Antigen processing and presentation pathways have been extensively studied, and computational models for predicting peptide binding affinity to some MHC alleles, especially class I HLAs, have achieved near perfect ROC-AUC 15, 71 for common alleles. Brophy, S. E., Holler, P. & Kranz, D. A yeast display system for engineering functional peptide-MHC complexes. Bagaev, D. V. et al.

Science 371, eabf4063 (2021). The ImmuneRACE Study: a prospective multicohort study of immune response action to COVID-19 events with the ImmuneCODETM Open Access Database.
