Antigen processing and remodeling of the endosomal pathway: requirements for antigen cross-presentation. [PDF]
The cross-presentation of endocytosed antigen as peptide/class I MHC complexes plays a central role in the elicitation of CD8+ T cell clones that mediate anti-viral and anti-tumor immune responses.

Regulation of the Cell Biology of Antigen Cross-Presentation [PDF]
Antigen cross-presentation is an adaptation of the cellular process of loading MHC-I molecules with endogenous peptides during their biosynthesis within the endoplasmic reticulum. Cross-presented peptides derive from internalized proteins, microbial pathogens, and transformed or dying cells.

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

Pathways for antigen cross presentation
Dendritic cells (DCs) have the unique ability to capture cellular tissue antigens, and to present them on MHC class I molecules to antigen-specific CD8(+) T lymphocytes after migration to the draining lymph nodes. This process, called "cross presentation" can lead either to the tolerization or activation of antigen-specific CD8(+) T cells.

Beyond Just Peptide Antigens: The Complex World of Peptide-Based Cancer Vaccines [PDF]
Peptide-based cancer vaccines rely upon the strong activation of the adaptive immune response to elicit its effector function. They have shown to be highly specific and safe, but have yet to prove themselves as an efficacious treatment for cancer in the ...

Live Long and Prosper for Antigen Cross-Presentation [PDF]
Even though proteolytic antigen fragments are displayed for cross-presentation, rapid proteolysis of endocytosed antigens inhibits this process. In this issue of Immunity, Alloatti et al. (2015) describe how maturing dendritic cells keep phagosomes and lysosomes apart to ensure extended antigen life that leads to prosperous cross-presentation.

Understanding the biology of antigen cross-presentation for the design of vaccines against cancer
Antigen cross-presentation, the process in which exogenous antigens are presented on MHC class I molecules, is crucial for the generation of effector CD8+ T cell responses.

The purinergic receptor P2X7 as a modulator of viral vector-mediated antigen cross-presentation [PDF]
IntroductionModified Vaccinia Virus Ankara (MVA) is a safe vaccine vector inducing long- lasting and potent immune responses. MVA-mediated CD8+T cell responses are optimally induced, if both, direct- and cross-presentation of viral or recombinant ...
