CD69 expression in T cells interacted with antigen-pulsed HMDCs. After coculture with antigen-pulsed HMDCs (Com1-DCs/HspB-DCs), mock-pulsed HMDCs (Mock-DCs), or PHA (positive control), CD69 expression on the surfaces of CD4+ and CD8+ cells were determined in T cells. The percentages of double-positive cells among the T cells are indicated in the top-right corner, and the results are representative of three independent experiments, each using cells derived from a different donor.
