RETRACTED: Polychlorinated biphenyls induce proinflammatory cytokine release and dopaminergic dysfunction: Protection in interleukin-6 knockout mice

This article has been retracted at the request of the authors. Please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).Reason: the authors have recently come to the conclusion that some of the Western blot data in the published manuscript is not correct. Athough they believe that this cytokine deficiency is likely to influence neuroinflammation and the loss of dopamine, the analysis of dopamine transporter and the expression of the other associated proteins are not accurate. Since they have no confidence in this data, we must retract this paper. The Editor-in-Chief concurs with the authors' request and has authorized retraction.
