In the article, “Induction of IL-33 expression and activity in central nervous system glia,” by Chad A. Hudson, George P. Christophi, Ross C. Gruber, Joel R. Wilmore, David A. Lawrence, and Paul T. Massa, which appeared in Volume 84, September 2008, of the Journal of Leukocyte Biology (doi: 10.1189/jlb.1207830), Figure 2A should have been published in color. The corrected figure appears below. This article has been corrected online. The publishers regret any inconvenience caused by this error.
Figure 2.
Induction of IL-33 in astrocytes. (A) CNS glial cultures were treated with dsRNA and LPS for 8 h and then fixed and immunostained for IL-33 (purple) and the astrocyte marker GFAP (red). The red arrows indicate dsRNA-and LPS-treated astrocytes, and the black arrows indicate untreated astrocytes (at 40× and 63×). (B) Secreted levels of IL-33 from glial cultures treated with LPS, PAM3Cys, or dsRNA. Each graph is the result of an independent experiment that used multiple, independently produced cultures. Statistical significance was measured via one-way ANOVA, followed by the Student-Neuman-Keuls method. *, P < 0.05, for that treatment versus control. P, PAM3Cys [that treatment being significantly greater (P<0.05) than the treatment indicated by that letter].
