Publisher Correction: Bacterial butyrate prevents atherosclerosis.

ABSTRACT

In the version of this News & Views originally published, owing to production error, the concentration scales given for butyrate circulates in the bloodstream and colon were incorrect. It was stated that "butyrate circulates at mM levels (as opposed to µM in colon)"; this should have read "butyrate circulates at µM levels (as opposed to mM in colon)". This error has now been corrected.
