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. WebCross-presentation through the cytosolic pathway is sensitive to proteasome inhibi-tors2, which suggests that internalized proteins access the cytosol, where they are degraded by the protea-some.
