Uehara, A., Y. Fujimoto, A. Kawasaki, S. Kusumoto, K. Fukase, and H. Takada. 2006. Meso-diaminopimelic acid and meso-lanthionine, amino acids specific to bacterial peptidoglycans, activate human epithelial cells through NOD1. J. Immunol. 177: 1796–1804 .

In Fig. 5,B, the expression of β-defensin 2 induced by meso-DAP on HO-1-u-1, HEp-2, and SW620 cells has been revised. The results and conclusions of the paper remain unchanged. The corrected Fig. 5 B is shown below and the legend has been added for clarity.

FIGURE 5.

B, Induction of β-defensin 2 in human epithelial cells triggered by meso-DAP. Oral epithelial HO-1-u-1, pharyngeal epithelial HEp-2, esophageal epithelial TE-1, colonic epithelial SW620, and cervical epithelial HeLa cells were incubated for 24 h in the presence or absence of 100 μg/ml meso-DAP, dd-DAP, or ll-DAP. After fixation, cells were treated with anti-β-defensin 2 Ab or goat IgG and then visualized with Alexa Fluor 488 (green). Nuclei were visualized by staining with DAPI blue. Scale bar, 20 μM.
