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. WebJul 4, 2024 · Cross-presentation via the vacuolar pathway is thought to depend on the generation of the appropriate peptides by phagosomal or lysosomal proteases (Song & Harding, 1996; Campbell et al, 2000; Shen et al, 2004), while cross-presentation by the cytosolic pathway is believed to be enhanced by a reduction in lysosomal proteolysis … childs picture dictionaryWebResearch into this field has described two main mechanisms of cross-presentation, the cytosolic pathway and the vacuolar pathway.

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.
