WebJun 20, 2016 · Exogenous antigens are cross-presented through two main pathways, often referred to as ‘vacuolar’ and ‘cytosolic’ 2. Cross-presentation through the ‘vacuolar’ pathway is independent of the transporter associated with antigen processing (TAP) and resistant to proteasome inhibitors. WebJan 28, 2024 · Additionally, cross-presentation was disrupted by proteasome inhibitors (13–16), consistent with a model in which antigens are delivered into the cytosol before proteasomal degradation and peptide import into the ER. This pathway, later termed the “cytosolic pathway,” implies the export of antigens from endocytic compartments to the … can a business buy landIn 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.

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.
