Interaction of human heat shock protein 70 with tumor-associated peptides [PDF]

open access: yes, 2009
Molecular chaperones of the heat shock protein 70 (Hsp70) family play a crucial role in the presentation of exogenous antigenic peptides by antigen-presenting cells (APCs).

Assessment of roles for calreticulin in the cross-presentation of soluble and bead-associated antigens. [PDF]

open access: yesPLoS ONE, 2012
Antigen cross-presentation involves the uptake and processing of exogenously derived antigens and their assembly with major histocompatibility complex (MHC) class I molecules.

Cross-presentation of exogenous antigens on MHC I molecules

open access: yesCurrent Opinion in Immunology, 2020
In order to get recognized by CD8 T cells, most cells present peptides from endogenously expressed self or foreign proteins on MHC class I molecules. However, specialized antigen-presenting cells, such as DCs and macrophages, can present exogenous antigen on MHC-I in a process called cross-presentation. This pathway plays key roles in antimicrobial and

Sec61 blockade by mycolactone inhibits antigen cross-presentation independently of endosome-to-cytosol export

open access: yes, 2017
Although antigen cross-presentation in dendritic cells (DCs) is critical to the initiation of most cytotoxic immune responses, the intracellular mechanisms and traffic pathways involved are still unclear.

Restoration of cytomegalovirus antigen presentation by gamma interferon combats viral escape. [PDF]

open access: yes, 1994
An immediate-early protein of murine cytomegalovirus (MCMV), pp89, elicits an immunodominant and protective major histocompatibility complex (MHC) class I Ld-restricted CD8+ T-lymphocyte response.

Endocytic Recycling of MHC Class I Molecules in Non-professional Antigen Presenting and Dendritic Cells

open access: yesFrontiers in Immunology, 2019
Major histocompatibility complex class I (MHC I) molecules are glycoproteins that display peptide epitopes at the cell surface of nucleated cells for recognition by CD8+ T cells.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Tumor antigen cross-presentation and the dendritic cell: Where it all begins? [PDF]

open access: yes, 2010
Dendritic cells (DCs) are professional antigen-presenting cells (APCs) that are critical for the generation of effective cytotoxic T lymphocyte (CTL) responses; however, their function and phenotype are often defective or altered in tumor-bearing hosts ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Varicellovirus UL 49.5 proteins differentially affect the function of the transporter associated with antigen processing, TAP [PDF]

open access: yes, 2008
Cytotoxic T-lymphocytes play an important role in the protection against viral infections, which they detect through the recognition of virus-derived peptides, presented in the context of MHC class I molecules at the surface of the infected cell.
