Quantitative analysis of D^bNP₃₆₆⁺ and D^bPA₂₂₄⁺ CD8⁺ T cells following influenza vaccination with an adjuvant. The B6 mice were immunized with iIAV ± α-GalCer, and lymphocytes from the spleen and brachial lymph node (BLN) were sampled 7 days later. The percentage (A and B) and absolute number (C and D) of tetramer-positive populations was evaluated among the CD8⁺ T cells in the spleen (A and C) and BLN (B and D). Results are expressed as mean ± SD for groups of 5 mice. *P < 0.05; **P < 0.01.
