In the originally published version of this article, the competing interests statement indicated that the authors had no competing interests; however, this statement was incorrect. The statement should have read as follows: ‘M.H. receives a consultation fee from IFM Therapeutics, LLC for consultations regarding the pathogenesis and interventional strategies of neurodegenerative disease. E.L. is a scientific co-founder and consultant to IFM Therapeutics. R.M.M. declares no competing interests.’ This error has been corrected in the HTML and PDF versions of the article.
