JNeurosci is publishing an Expression of Concern for the article, “Dissociating β-Amyloid from α7 Nicotinic Acetylcholine Receptor by a Novel Therapeutic Agent, S 24795, Normalizes α7 Nicotinic Acetylcholine and NMDA Receptor Function in Alzheimer's Disease Brain,” by Hoau-Yan Wang, Andres Stucky, JingJing Liu, Changpeng Shen, Caryn Trocme-Thibierge, and Philippe Morain, which appeared on pages 10961–10973 of the September 2, 2009 issue. The editors have been made aware of concerns about Western blots in this study. These and other concerns are currently under investigation by the academic authorities at the City University of New York (CUNY). JNeurosci will await the outcome of that investigation before taking further action.
