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… WebbDer MHC-Klasse-I-Proteinkomplex besteht aus einer größeren, an der Zellmembran verankerten, Untereinheit; der schweren Kette (heavy chain, HC) und einer kleineren …
