【Abstract】

<正>Cytosolic short-lived proteins and defective ribosomal products(DRi Ps)were shown to constitute the major antigen source for direct MHC class I(MHCI)presentation.Yet,efficient MHCI dependent immune responses to exogenous proteins require cross presentation by professional Antigen Presenting Cells(APCs),such as dendritic cells(DC).It is hard to envision how extremely short-lived proteins,such as DRi Ps,
