The authors would like apologise by an involuntary mistake we made: the Fig. 2A of the FASEB J article (Alvarez et al., 2008, doi: https://doi.org/10.1096/fj.07-10271) was partially reproduced in Fig. 6B of this NBD paper. This does not modify the conclusions of the NBD article. We contacted the FASEB J and permission to reproduce the figure was granted. NBD article: doi: https://doi.org/10.1016/j.nbd.2010.09.008.
