ROC-AUC and the area under the precision–recall curve (PR-AUC) are measures of model tendency to different classes of error. Competing models should be made freely available for research use, following the commendable example set in protein structure prediction 65, 70. This matters because many epitopes encountered in nature will not have an experimentally validated cognate TCR, particularly those of human or non-viral origin (Fig. Science a to z puzzle answer key 4 8. Biological structure and function emerge from scaling unsupervised learning to 250 million protein sequences. However, these approaches assume, on the one hand, that TCRs do not cross-react and, on the other hand, that the healthy donor repertoires do not include sequences reactive to the epitopes of interest. Pearson, K. On lines and planes of closest fit to systems of points in space. The scale and complexity of this task imply a need for an interdisciplinary consortium approach for systematic incorporation of the latest immunological understandings of cellular immunity at the tissue level and cutting-edge developments in the field of artificial intelligence and data science.

However, the advent of automated protein structure prediction with software programs such as RoseTTaFold, ESMFold and AlphaFold-Multimer provide potential opportunities for large-scale sequence and structure interpretations of TCR epitope specificity 63, 64, 65. Common unsupervised techniques include clustering algorithms such as K-means; anomaly detection models and dimensionality reduction techniques such as principal component analysis 80 and uniform manifold approximation and projection.

Clustering is achieved by determining the similarity between input sequences, using either 'hand-crafted' features such as sequence distance or enrichment of short sub-sequences, or by comparing abstract features learnt by DNNs (Table 1). Birnbaum, M. Deconstructing the peptide-MHC specificity of T cell recognition. Pavlović, M. The immuneML ecosystem for machine learning analysis of adaptive immune receptor repertoires. Heikkilä, N. Human thymic T cell repertoire is imprinted with strong convergence to shared sequences. High-throughput library screens such as these provide opportunities for improved screening of the antigen–MHC space, but limit analysis to individual TCRs and rely on TCR–MHC binding instead of function. Fischer, D. S., Wu, Y., Schubert, B. Indeed, concerns over nonspecific binding have led recent computational studies to exclude data derived from a 10× study of four healthy donors 27. Nature 547, 89–93 (2017). Cell 157, 1073–1087 (2014). Nolan, S.

Lanzarotti, E., Marcatili, P. & Nielsen, M. T-cell receptor cognate target prediction based on paired α and β chain sequence and structural CDR loop similarities. Other groups have published unseen epitope ROC-AUC values ranging from 47% to 97%; however, many of these values are reported on different data sets (Table 1), lack confidence estimates following validation 46, 47, 48, 49 and have not been consistently reproducible in independent evaluations 50. A comprehensive survey of computational models for TCR specificity inference is beyond the scope intended here but can be found in the following helpful reviews 15, 38, 39, 40, 41, 42. In the absence of experimental negatives, negative instances may be produced by shuffling or drawing randomly from healthy donor repertoires 9. Zhang, W.

We encourage validation strategies such as those used in the assessment of ImRex and TITAN 9, 12 to substantiate model performance comparisons. Nguyen, A. T., Szeto, C. & Gras, S. The pockets guide to HLA class I molecules. However, we believe that several critical gaps must be addressed before a solution to generalized epitope specificity inference can be realized. Finally, we describe how predicting TCR specificity might contribute to our understanding of the broader puzzle of antigen immunogenicity.

Many groups have attempted to bypass this complexity by predicting antigen immunogenicity independent of the TCR 14, as a direct mapping from peptide sequence to T cell activation. JCI Insight 1, 86252 (2016). G. is a co-founder of T-Cypher Bio. Possible answers include: A - astronomy, B - Biology, C - chemistry, D - diffusion, E - experiment, F - fossil, G - geology, H - heat, I - interference, J - jet stream, K - kinetic, L - latitude, M -. Among the most plausible explanations for these failures are limitations in the data, methodological gaps and incomplete modelling of the underlying immunology. At the time of writing, fewer than 1 million unique TCR–epitope pairs are available from VDJdb, McPas-TCR, the Immune Epitope Database and the MIRA data set 5, 6, 7, 8 (Fig. Genomics Proteomics Bioinformatics 19, 253–266 (2021).

Third, an independent, unbiased and systematic evaluation of model performance across SPMs, UCMs and combinations of the two (Table 1) would be of great use to the community. Therefore, thoughtful approaches to data consolidation, noise correction, processing and annotation are likely to be crucial in advancing state-of-the-art predictive models. This technique has been widely adopted in computational biology, including in predictive tasks for T and B cell receptors 49, 66, 68. ELife 10, e68605 (2021). Gilson, M. BindingDB in 2015: a public database for medicinal chemistry, computational chemistry and systems pharmacology. 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. T cells typically recognize antigens presented on members of the MHC protein family via highly diverse heterodimeric T cell receptors (TCRs) expressed at their surface (Fig. Machine learning models may broadly be described as supervised or unsupervised based on the manner in which the model is trained. Taxonomy is the key to organization because it is the tool that adds "Order" and "Meaning" to the puzzle of God's creation. Liu, S.

Nature Reviews Immunology thanks M. Birnbaum, P. Holec, E. Newell and the other, anonymous, reviewer(s) for their contribution to the peer review of this work. Rep. 6, 18851 (2016). Although some DNN-UCMs allow for the integration of paired chain sequences and even transcriptomic profiles 48, they are susceptible to the same training biases as SPMs and are notably less easy to implement than established clustering models such as GLIPH and TCRdist 19, 54. Neural networks may be trained using supervised or unsupervised learning and may deploy a wide variety of different model architectures. Pan, X. Combinatorial HLA-peptide bead libraries for high throughput identification of CD8+ T cell specificity. Unlike SPMs, UCMs do not depend on the availability of labelled data, learning instead to produce groupings of the TCR, antigen or HLA input that reflect the underlying statistical variations of the data 19, 51 (Fig. Broadly speaking, current models can be divided into two categories, which we dub supervised predictive models (SPMs) (Fig.
