Neo-Splicetopes in Tumor Therapy: A Lost Case?
Frontiers in Immunology, 2022 Proteasome generates spliced peptides by ligating two distant cleavage products in a reverse proteolysis reaction. The observation that CD8+ T cells recognizing a spliced peptide induced T cell rejection in a melanoma patient following adoptive T cell ...

Proteases: essential actors in processing antigens and intracellular Toll-like receptors
Frontiers in Immunology, 2013 MHC class II molecules expressed by professional antigen presenting cells (pAPCs) such as macrophages, B cells and dendritic cells (DCs) play a fundamental role in presenting peptides to CD4+ T cells.

Can ERAP1 and ERAP2 Form Functional Heterodimers? A Structural Dynamics Investigation
Frontiers in Immunology, 2022 Endoplasmic reticulum aminopeptidases 1 and 2 (ERAP1 and ERAP2) play important roles in the generation of antigenic peptides presented by Major Histocompatibility Class I (MHCI) molecules and indirectly regulate adaptive immune responses.

The antigen processing pathway in B lymphocytes
, 1990 Monovalent antigen bound to membrane immunoglobulin on human B lymphoblastoid cells is endocytosed through coated pits and passes sequentially from a site which actively recycles membrane to the cell surface and then to a proteolytically active ...

Identification of proteases employed by dendritic cells in the processing of protein purified derivative (PPD) [PDF]
, 2004 Dendritic cells (DC) are known to present exogenous protein Ag effectively to T cells. In this study we sought to identify the proteases that DC employ during antigen processing.

Current Concepts of Antigen Cross-Presentation
Frontiers in Immunology, 2018 Dendritic cells have the ability to efficiently present internalized antigens on major histocompatibility complex (MHC) I molecules. This process is termed cross-presentation and is important role in the generation of an immune response against viruses ...

A loop structure allows TAPBPR to exert its dual function as MHC I chaperone and peptide editor
eLife, 2020 Adaptive immunity vitally depends on major histocompatibility complex class I (MHC I) molecules loaded with peptides. Selective loading of peptides onto MHC I, referred to as peptide editing, is catalyzed by tapasin and the tapasin-related TAPBPR.

The Function of Immunoproteasomes—An Immunologists’ Perspective
Cells, 2021 Proteasomes are responsible for intracellular proteolysis and play an important role in cellular protein homeostasis. Cells of the immune system assemble a specialized form of proteasomes, known as immunoproteasomes, in which the constitutive catalytic ...

Antigen Processing of a Short Viral Antigen by Proteasomes [PDF]
Journal of Biological Chemistry, 2006 Mass spectrometry (MS)-based methods coupled to reverse phase chromatography separation are a useful technology to analyze complex peptide pools that are comprised of different peptides with unrelated sequences. In antigen presentation, proteasomes generate a set of short peptides that are closely related and overlapping and in some instances may even ...

Cross-presentation of cell-associated antigens by MHC class I in dendritic cell subsets
Frontiers in Immunology, 2015 Dendritic cells have the unique ability to pick up dead cells carrying antigens in tissue and migrate to the lymph nodes where they can cross-present cell-associated antigens by MHC class I to CD8+ T cells. There is strong in vivo evidence that the mouse
