Antigen Presentation in Transplantation [PDF]

open access: yesTrends in Immunology, 2016
Transplantation of solid organs between genetically distinct individuals leads, in the absence of immunosuppression, to T cell-dependent transplant rejection. Activation of graft-reactive T cells relies on the presentation of transplant-derived antigens (intact donor MHC molecules or processed peptides on host MHC molecules) by mature dendritic cells ...

Direct antigen presentation is the canonical pathway of cytomegalovirus CD8 T-cell priming regulated by balanced immune evasion ensuring a strong antiviral response

open access: yesFrontiers in Immunology, 2023
CD8 T cells are important antiviral effectors in the adaptive immune response to cytomegaloviruses (CMV). Naïve CD8 T cells can be primed by professional antigen-presenting cells (pAPCs) alternatively by “direct antigen presentation” or “antigen cross ...

The ABCs of Antigen Presentation by Stromal Non-Professional Antigen-Presenting Cells [PDF]

open access: yesInternational Journal of Molecular Sciences, 2021
Professional antigen-presenting cells (APCs), such as dendritic cells and macrophages, are known for their ability to present exogenous antigens to T cells. However, many other cell types, including endothelial cells, fibroblasts, and lymph node stromal cells, are also capable of presenting exogenous antigens to either CD8+ or CD4+ T cells via cross ...

Presentation of CMV immediate-early antigen to cytolytic T lymphocytes is selectively prevented by viral genes expressed in the early phase [PDF]

open access: yes, 1989
The regulation of antigen processing and presentation to MHC class I-restricted cytolytic T lymphocytes was studied in cells infected with murine cytomegalovirus. Recognition by cytolytic T lymphocytes of the phosphoprotein pp89, the immunodominant viral

Chemokine (C-C Motif) Receptor 2 Mediates Dendritic Cell Recruitment to the Human Colon but Is Not Responsible for Differences Observed in Dendritic Cell Subsets, Phenotype, and Function Between the Proximal and Distal ColonSummary

open access: yesCellular and Molecular Gastroenterology and Hepatology, 2016
Background & Aims: Most knowledge about gastrointestinal (GI)-tract dendritic cells (DC) relies on murine studies where CD103+ DC specialize in generating immune tolerance with the functionality of CD11b+/− subsets being unclear.

Cytomegalovirus prevents antigen presentation by blocking the transport of peptide-loaded major histocompatibility complex class I molecules into the medial-Golgi compartment [PDF]

open access: yes, 1992
Selective expression of murine cytomegalovirus (MCMV) immediate-early (IE) genes leads to the presentation by the major histocompatibility complex (MHC) class I molecule L a of a peptide derived from MCMV IE protein pp89 (Reddehase, M. J., J.

Chemotherapy enhances cross-presentation of nuclear tumor antigens. [PDF]

open access: yesPLoS ONE, 2014
Cross-presentation of tumor antigen is essential for efficient priming of naïve CD8⁺ T lymphocytes and induction of effective anti-tumor immunity. We hypothesized that the subcellular location of a tumor antigen could affect the efficiency of cross ...

Antigen presentation in uveitis [PDF]

open access: yesEye, 1997
Experimental autoimmune uveoretinits (EAU) is not only a valuable model for human inflammatory eye diseases, it is also a useful system for studying many aspects of immunobiology. One such aspect is self/non-self discrimination, the ability of the immune system to tolerate self molecules while responding aggressively to foreign antigens. Our laboratory

Antigen-presentation of non-peptidic antigens lipid trafficking and loading [PDF]

open access: yes, 2010
T cells recognize a broad variety of antigens, including peptides, lipids and non-peptidic phosphorylated metabolites. Clarification of the rules rendering non-peptidic molecules immunogenic is essential to understand and to influence the reactions of ...

Promising Extracellular Vesicle-Based Vaccines against Viruses, Including SARS-CoV-2

open access: yesBiology, 2021
Extracellular vesicles (EVs) are secreted from almost all human cells and mediate intercellular communication by transferring heterogeneous molecules (i.e., DNA, RNAs, proteins, and lipids).
