ProteomicsHLA binding of self-peptides is biased towards proteins with specific molecular functions
Human leukocyte antigen (HLA) is highly polymorphic and plays a key role in guiding adaptive immune responses by presenting foreign and self peptides to T cells. Each HLA variant selects a minor fraction of peptides that match a certain motif required for optimal interaction with the peptide-binding...

ProteomicsUnveiling the Peptide Motifs of HLA-C and HLA-G from Naturally Presented Peptides and Generation of Binding Prediction Matrices
The classical HLA-C and the nonclassical HLA-E and HLA-G molecules play important roles both in the innate and adaptive immune system. Starting already during embryogenesis and continuing throughout our lives, these three Ags exert major functions in immune tolerance, defense against infections, and...

ProteomicsUnsupervised mining of HLA-I peptidomes reveals unsuspected false positives and new binding motifs
Modern antigen vaccine designs and studies of human leukocyte antigen (HLA)-mediated immune responses rely heavily on the knowledge of HLA allele-specific binding motifs and computational prediction of antigen-HLA binding affinity. Breakthroughs in HLA peptidomics have considerably expanded the data...

ProteomicsThe landscape of the SARS-CoV-2 HLA-peptidome
The human leukocyte antigen (HLA)-bound-viral antigens, serve as an immunological signature that can be selectively recognized by T cells. As viruses evolve by acquiring mutations, it is essential to identify a range of viral presented antigens. Utilizing HLA-peptidomics we Identified SARS-CoV-2-der...

ProteomicsThe HLA ligandome comprises a limited repertoire of O-GlcNAcylated antigens preferentially associated with HLA-B07:02
Mass-spectrometry based immunopeptidomics has provided unprecedented insights into antigen presentation, not only charting an enormous ligandome of self-antigens, but also cancer neo-antigens and peptide antigens harbouring post-translational modifications. Here we concentrate on the latter, focusin...

Proteomicsthe landscape of phosphorylated HLA-I ligands
The identification and prediction of HLA-I–peptide interactions play an important role in our understanding of antigen recognition in infected or malignant cells. In cancer, non-self HLA-I ligands can arise from many different alterations, including non-synonymous mutations, gene fusion, cancer-spec...

Specific alterations in protein post-translational modification (PTMs) are recognized hallmarks of diseases. These modifications potentially provide a unique disease-related source of Human Leukocyte Antigen (HLA) class I-presented peptide antigens that can elicit specific immune responses. Although...

ProteomicsIdentification of novel HLA class I-restricted hepatitis B virus peptides and their modulation by peptide editor TAPBPR
Hepatitis B virus (HBV) is the leading cause of hepatocellular carcinoma and infections remain a substantial global health problem for which no curative therapy exists. As cytotoxic CD8+ T lymphocytes are the principal effectors of natural HBV resolution, there is considerable interest in discoverin...

In the context of HLA-DP-mismatched allogeneic stem cell transplantation, mismatched HLA-DP alleles can provoke profound allo-HLA-DP-specific immune responses from the donor T-cell repertoire leading to graft-versus-leukemia effect and/or graft-versus-host disease in the patient. The magnitude of al...
