Following the publication of this paper, it was drawn to the Editors' attention by a concerned reader that data shown in various of the panels portraying the results from flow cytometric experiments in Fig. 2D, 5D and 6D were strikingly similar to data appearing in different form in other articles by different authors. Owing to the fact that the contentious data in the above article had already been published elsewhere, or were already under consideration for publication, prior to its submission to , the Editor has decided that this paper should be retracted from the Journal.
