Retraction

The authors would like to retract the article "The absence of MyD88 has no effect on the induction of alternatively activated macrophage during Fasciola hepatica infection" published in BMC Immunology (2011, 12:63). The text and figures in this article [1] have been misappropriated from a different set of experiments using a different parasite, conducted in the laboratory of Prof J Allen and presented in the thesis of K Mylonas. Lead author Dr HongLin Luo accepts full responsibility for this and would like to apologise to colleagues in the lab, the co-authors, Editors and readers. The other authors take no responsibility for the misappropriation.
