Tumor-derived microvesicles modulate antigen cross-processing via reactive oxygen species-mediated alkalinization of phagosomal compartment in dendritic cells [PDF]

open access: yes, 2017
Dendritic cells (DCs) are the only antigen-presenting cells able to prime naïve T cells and cross-prime antigen-specific CD8+ T cells. Their functionality is a requirement for the induction and maintenance of long-lasting cancer immunity.

Interferon-gamma-activated macrophages infected with Burkholderia cenocepacia process and present bacterial antigens to T-cells by class I and II major histocompatibility complex molecules

open access: yesEmerging Microbes and Infections, 2020
Burkholderia cenocepacia is an emerging opportunistic pathogen for people with cystic fibrosis and chronic granulomatous disease. Intracellular survival in macrophages within a membrane-bound vacuole (BcCV) that delays acidification and maturation into ...

The yin/yang balance of the MHC-self-immunopeptidome

open access: yesFrontiers in Immunology, 2022
The MHC-self immunopeptidome of professional antigen presenting cells is a cognate ligand for the TCRs expressed on both conventional and thymic-derived natural regulatory T cells.

Main Components of Fish Immunity: An Overview of the Fish Immune System

open access: yesFishes, 2023
Cellular immune responses consist of innate and adaptive cell-mediated immune mechanisms, where all leukocyte subpopulations are included. Among these are vital processes such as cell-mediated cytotoxicity and phagocytosis. The main cellular constituents

CD4+ Th immunogenicity of the Ascaris spp. secreted products [PDF]

open access: yes, 2020
Ascaris spp. is a major health problem of humans and animals alike, and understanding the immunogenicity of its antigens is required for developing urgently needed vaccines.

Pathways of Antigen Processing [PDF]

open access: yesAnnual Review of Immunology, 2013
T cell recognition of antigen-presenting cells depends on their expression of a spectrum of peptides bound to major histocompatibility complex class I (MHC-I) and class II (MHC-II) molecules. Conversion of antigens from pathogens or transformed cells into MHC-I- and MHC-II-bound peptides is critical for mounting protective T cell responses, and similar

The role of insulin-regulated aminopeptidase in MHC class I antigen presentation

open access: yesFrontiers in Immunology, 2012
Production of MHC I ligands from antigenic proteins generally requires multiple proteolytic events. While the proteolytic steps required for antigen processing in the endogenous pathway are clearly established, persisting gaps of knowledge regarding ...

Lysosomes and lysosome‐related organelles in immune responses

open access: yesFEBS Open Bio, 2022
The catabolic, degradative capacity of the endo‐lysosome system is put to good use in mammalian immune responses as is their recently established status as signaling platforms.

Making Insulin and Staying Out of Autoimmune Trouble: The Beta-Cell Conundrum

open access: yesFrontiers in Immunology, 2021
Autoimmune type 1 diabetes (T1D) results from the intricate crosstalk of various immune cell types. CD8+ T cells dominate the pro-inflammatory milieu of islet infiltration (insulitis), and are considered as key effectors of beta-cell destruction, through
