BCKDK and myocarditis: To test their ability to induce myocarditis individually, we selected a total of nine peptides, three from each of groups II (BCKDk 61–80, BCKDk 71–90 and BCKDk 91–110), III (BCKDk 111–130, BCKDk 121–140, and BCKDk 141–160) and VIII (BCKDk 331–350, BCKDk 341–360, and BCKDk 351–370) (Supporting information Table S2).
