Neo-Splicetopes in Tumor Therapy: A Lost Case?

open access: yesFrontiers 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 ...

Can ERAP1 and ERAP2 Form Functional Heterodimers? A Structural Dynamics Investigation

open access: yesFrontiers 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.

Proteases: essential actors in processing antigens and intracellular Toll-like receptors

open access: yesFrontiers 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.

A loop structure allows TAPBPR to exert its dual function as MHC I chaperone and peptide editor

open access: yeseLife, 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

open access: yesCells, 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 ...

Current Concepts of Antigen Cross-Presentation

open access: yesFrontiers 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 ...

The Antigen Processing and Presentation Machinery in Lymphatic Endothelial Cells

open access: yesFrontiers in Immunology, 2019
Until a few years ago, lymphatic vessels and lymphatic endothelial cells (LEC) were viewed as part of a passive conduit for lymph and immune cells to reach lymph nodes (LN).

Dysfunction of antigen processing and presentation by dendritic cells in cancer.

open access: yesMolecular Immunology, 2019
The ability to mount an effective anti-tumor immune response requires coordinate control of CD4 T cell and CD8 T cell function by antigen presenting cells (APCs). Unfortunately, tumors create an immunosuppressive microenvironment that helps protect tumor

The ER Aminopeptidases, ERAP1 and ERAP2, synergize to self-modulate their respective activities

open access: yesFrontiers in Immunology, 2022
IntroductionCritical steps in Major Histocompatibility Complex Class I (MHC-I) antigen presentation occur in the endoplasmic reticulum (ER). In general, peptides that enter the ER are longer than the optimal length for MHC-I binding.

Selection of immunodominant epitopes during antigen processing is hierarchical.

open access: yesMolecular Immunology, 2019
MHC II proteins present processed antigens to CD4 + T cells through a complex set of events and players that include chaperons and accessory molecules.
