Correction for Heneka et al., Peroxisome Proliferator-Activated Receptor-γ Ligands Reduce Neuronal Inducible Nitric Oxide Synthase Expression and Cell Death In Vivo

In the article “Peroxisome Proliferator-Activated Receptor-γ Ligands Reduce Neuronal Inducible Nitric Oxide Synthase Expression and Cell Death In Vivo,” by Michael T. Heneka, Thomas Klockgether, and Douglas L. Feinstein, which appeared on pages 6862–6867 of the September 15, 2000 issue, two errors appeared in Materials and Methods. The amount of troglitazone injected was 1 nmol, not 100 nmol, and the amount of NS-398 injected was 1 nmol, not 10 nmol. The concentration of vehicle (DMSO) was 0.5% when troglitazone was injected and 1.5% when NS-398 was injected. The authors apologize to the editors, referees, and readers of The Journal of Neuroscience for these errors and any confusion that they may have caused.
