WebCross presentation of Antigens The presentation of exogenous antigens on MHC class I molecules is known as cross-presentation. It is essential for the initiation of CD8+ T cell responses. In vivo, cross-presentation is mainly carried out by specific dendritic cell (DC) subsets through an adaptation of their endocytic and phagocytic pathways ; WebAug 18, 2016 · DRibbles-associated antigens readily access the cytosolic pathway of cross-presentation. Strikingly, vaccination of lung tumor-bearing mice with DCs pulsed with DRibbles elicits higher protection against tumor growth than vaccination with DCs loaded with dying cells or cell lysates . DRibbles are also effective in human APCs.

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. 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.
