Cytosolic pathway cross-presentation
WebFIGURE 2 Schematic Overview of the Cytosolic Pathway of Cross-presentation. Antigens are internalized into the alkaline phagosomes by a process that is tightly regulated by various proteins, such as NADPH oxidases 2 (NOX2), Aquaporin 3(AQP3), and Rab39a. NOX2 complexes are recruited to the phagosomes by lysosome-related organelle (LRO) … In addition to solid structure uptake, dendritic cell phagocytosis simultaneously modifies the kinetics of endosomal trafficking and maturation. As a consequence, external soluble antigens are targeted into the MHC class I cross-presentation pathway instead of the MHC Class II pathway. However, there is still uncertainty in regard to a mechanistic pathway for cross presentation within an antigen presenting cell. Currently, there are two main pathways proposed, cytosolic and vac…

WebTwo pathways for cross-presentation have been characterized to date: the cytosolic and vacuolar pathways. Cross-presentation is typically mediated by the cytosolic pathway, in which antigen processing occurs in the cytosol in a proteasome- and transporter associated with antigen processing (TAP)-dependent manner. WebMar 30, 2010 · In fact, our findings reveal a highly efficient cross-presentation pathway in γδ T-APCs that involves the cytosolic route of MHC I loading. Antigen cross …
WebCytosolic pathway Many viruses produce immunoevasins that interfere with antigen presentation by MHC class I molecules.
