Prediction of Specific TCR-Peptide Binding From Large Dictionaries of TCR-Peptide Pairs

2019

Abstract The T cell repertoire is composed of T cell receptors (TCR) selected by their cognate MHC-peptides and naive TCR that do not bind known peptides. While the task of distinguishing a peptide-binding TCR from a naive TCR unlikely to bind any peptide can be performed using sequence motifs, distinguishing between TCRs binding different peptides requires more advanced methods. Such a prediction is the key for using TCR repertoires as disease-specific biomarkers. We here used large scale TCR-peptide dictionaries with state-of-the-art natural language processing (NLP) methods to produce ERGO (pEptide tcR matchinG predictiOn), a highly specific classifier to predict which TCR binds to which…

H2-M polymorphism in mice susceptible to collagen-induced arthritis involves the peptide binding groove.

1996

The ability to develop type II collagen (CII)-induced arthritis (CIA) in mice is associated with the major histocompatibilityI-A gene and with as yet poorly defined regulatory molecules of the major histocompatibility complex (MHC) class II antigen processing and presentation pathway. H2-M molecules are thought to be involved in the loading of antigenic peptides into the MHC class II binding cleft. We sequencedH2-Ma, H2-Mb1, andH2-Mb2 genes from CIA-susceptible and-resistant mouse strains and identified four differentMa andMb2 alleles and three differentMb1 alleles defined by polymorphic residues within the predicted peptide binding groove. Most CIA-resistant mouse strains share commonMa, M…

PATHOGENESIS OF HUMAN LEUKOCYTE ANTIGEN B27–POSITIVE ARTHRITIS

1998

Acute reactive arthritis, spondyloarthropathy (SpA) in association with chronic inflammatory bowel disease (IBD) and ankylosing spondylitis (AS), although differing in individual presentation and in the natural course of disease, have in common a strong association with human leukocyte antigen (HLA)-B27 and a possible involvement of other genetic and also environmental factors. This group of related diseases belonging to the seronegative SpAs represents the clearest example of HLA class 1–linked disease in humans. Several newly emerging animal models of the SpAs, which have been reviewed in this issue of the Rheumatic Disease Clinics of North America , have permitted us to investigate the i…
