A significant portion of the manuscript of Loiseau, P. M. and Bories C. entitled “Mechanisms of Drug Action and Drug Resistance in Leishmania as Basis for Therapeutic Target Identification and Design of Antileishmanial Modulators” Curr. Top. Med. Chem. 2006, 6, 539-550 was copied verbatim from the paper of M. Ouellette, J. Drummelsmith, and B. Papadopoulou entitled “Leishmaniasis: drugs in the clinic, resistance and new developments” Drug Res. Updates 2004, 7, 257-266. Therefore, Curr. Top. Med. Chem. has formally retracted the citation Loiseau, P. M.; Bories, C. Curr. Top. Med. Chem. 2006, 6, 539-550 from publication.
