Retraction Statement: Anti-inflammatory properties of tianeptine on lipopolysaccharide-induced changes in microglial cells involve toll-like receptor-related pathways.

'Anti-inflammatory properties of tianeptine on lipopolysaccharide-induced changes in microglial cells involve toll-like receptor-related pathways' by Slusarczyk, J., Trojan, E., Glombik, K., Piotrowska, A., Budziszewska, B., Kubera, M., Popiolek-Barczyk, K., Lason, W., Mika, J. and Basta-Kaim, A. The above article from the Journal of Neurochemistry published on 14 February 2016 on Wiley Online Library ( www.onlinelibrary.com), and in Volume 136, pp. 958-970, is being retracted by agreement between the corresponding author Agnieszka Basta-Kaim, the Journal's Editor-in-Chief Jörg Schulz, and John Wiley & Sons Ltd. The Editorial Office was alerted by a science journalist that the same Western Blot lane had been used to represent two different proteins. The Western Blot signal of iNOS in Fig. 4a was supposedly identical to the Western Blot signal of phospho-JNK in Fig. 6b. The corresponding author stated that "on the final step of figure 6 preparation the first author made, by mistake, an incorrect attachment of representative p-JNK blots." A corrected Fig. 6b is enclosed below. The second concern reaching the Editorial Office was that the same Western Blot signal appeared to have been used to represent two different experimental conditions: the iNOS control signal (-/- LPS/TIA Fig. 4a) appears as a horizontal and vertical mirror image of the last signal in this line (+/10 LPS/TIA Fig. 4a). The raw membrane which was used to produce Fig. 4a is enclosed on the next page and highlights the steps that were undertaken during figure preparation. Although the initial concern was not proven, concerns remained regarding the question how an inadvertent flipping of the first Western blot lane could happen. A corrected Fig. 4a prepared by the corresponding author from the raw image of iNOS western blot depicted above, without flipped first lane, is presented below: Although the corresponding author provided a large amount of evidence to explain disparities in the presentation of Western Blot images, due to the number of inconsistencies that were revealed during review of the provided evidence and the inability to confirm the nature of the steps that led to them, it was felt that the above mentioned Western Blot images presented in this publication were not reliable, even if the conclusions may still be valid. The first author would like to apologize to the readers, reviewers and editors of Journal of Neurochemistry for the errors.
