Intracellular cytokine production of CD4+ T cells from the short-term T cell line of donor 5. Cells were restimulated on day 8 with costimulatory molecules and with or without peptide. In this donor, moderate cytokine production was found in response to H161, H167, H443, and H482. The percentages of CD3+ CD4+ cells positive for the staining are depicted
