MMP, matrix metalloproteinase; OVA_323–339, ovalbumin peptide. ^a Mean ± standard error of the mean (SEM) difference in ear swelling between the PBS-treated ear and the peptide-treated ear. ^*P < 0.05, ^**P < 0.01, ^***P < 0.001 difference between PBS-treated ear and the peptide-treated ear (Student's t test); ^†P < 0.05 difference between the M. tuberculosis/IFA-immunized group and the naïve group (Mann–Whitney test); ^‡P < 0.05 difference between the M. tuberculosis/IFA-immunized group at day 20 and at day 27 (Mann–Whitney test). ND, not determined.
