We then selected a large number of H1-HA-specific T cell clones derived from naive or memory T cells of donor HD1 and determined their functional avidity by measuring the proliferative response to autologous monocytes pulsed with different concentrations of the H1-HA peptides or H1-HA protein, which need processing for presentation on MHC-II molecules. ./cache/cord-013093-aa4cf44u.txt ./txt/cord-013093-aa4cf44u.txt
