Method Primary source [7] abstract: "[Investigators] have visualized the fate and dynamics of intracellular peptides in living cells." Primary source [66] abstract: "Using L929 cells [mouse], [investigators] quantitated the macroeconomics of protein synthesis and degradation and the microeconomics of producing MHC class I associated peptides from viral translation products."
Comments P.959 left column bottom paragraph: "Using a substrate targeted for rapid and complete destruction, the efficiency of antigen processing was found to be one complex generated per 2,000 proteins degraded (Figs 3 and 4). This low efficiency does not seem to be a peculiarity of L929 cells, as professional APCs (bone-marrow-derived dendritic cells and peritoneal macrophages) were equally efficient at peptide generation [primary source 66]."
