WebClass I MHC is expressed by all host cells, except for non- nucleated ones, such as erythrocytes. When these cells are infected with a intracellular pathogen, the cells degrade foreign proteins via antigen processing. These result in peptide fragments, some of which are presented by MHC Class I to the T cell antigen receptor (TCR) on CD8 + T cells.
