In the Acknowledgements section of this article one of grant numbers relating to the National Institute of Health Carlos III (Fund for Health Research FIS, Spain) was missing. The section should have been as below.

We would like to thank Dr. Glòria Oliveras Serrat and Ms. Yaiza Martin Gonzalez for the preparation of the tissue histological sections. The study was supported by grant no. PI13/01257 and PI16/01335 (to A.L.-B.) from the National Institute of Health Carlos III (Fund for Health Research FIS, Spain), project co-financed by FEDER.

The original article has been corrected.
