Veldman, C., A. Höhne, D. Dieckmann, G. Schuler, and M. Hertl. 2004. Type I regulatory T cells specific for desmoglein 3 are more frequently detected in healthy individuals than in patients with pemphigus vulgaris. J. Immunol. 172: 6468–6475.
Fig. 2 of this article shows identical FACS images for the mIgG1 isotype control for CD25, CCR4, and TGF-β (all mouse IgG1-PE) as well as HLA-DR, CD45RO (both mouse IgG2a-PE), and CCR7 (rat IgG2a-PE), which is due to the use of inappropriate isotype controls by the first author of the study. Because we cannot rule out that observed differences in the expression patterns of HLA-DR, CD45RO, and CCR7 may be less significant when compared to the appropriate Ab isotype controls, these data have now been omitted in the revised Fig. 2, below. In addition, we have inserted an FACS image for CTLA-4 expression of the Th2 cells from the same original experiment. CTLA-4 expression was detected by a Cytochrome-labeled Ab (clone BNI3.1). The major observation of Fig. 2 that desmoglein 3-reactive Tr1 cells, but not Th2 cells, express glucocorticoid-induced TNFR and TGF-β is not affected by this revision. In Figs. 3, 4, and 5, proliferative T cell responses are expressed as mean cpm [3H]TdR ± SD. The authors apologize to the scientific community for any inconvenience these errors may have caused.
