mRNA expression of T- and B-cell chemoattractants and their cell markers in 64 EM lesions, 11 BL lesions, 25 ACA lesions, and 25 normal skin samples relative to the GAPDH gene. Data are shown in box plots in which the boxes represent the 25th and 75th percentiles, the lines within the boxes represent the median values, and the lines outside the boxes represent the 5th and 95th percentiles. A difference between normal and lesional skin (*), between EM and BL or EM and ACA lesions (**), or between BL and ACA lesions (§) at the 0.05 level is indicated above the bars. High levels of the CD8+ and Th1-type CD4+ T-cell chemoattractants CXCL9 and CXCL10 were found in EM and ACA lesions, whereas BL lesions had high levels of the B-cell chemoattractant CXCL13 and proportionally lower levels of CXCL9 and CXCL10.
