Antigen for major histocompatibility complex (MHC) class II presentation can be provided by phagocytosis or macroautophagy. Cytosolic pathogens are delivered to MHC class II containing compartments (MIICs) via macroautophagy for antigen loading. Extracellular pathogens reach this MHC class II loading compartment via endocytosis, which might be in some instances be facilitated by ATG8/LC3 coupled to the phagosome.
