Additionally, CTLs subpurified from PBS-inoculated F15-NOD Nfκb1 heterozygote mice have been shown to be activated and proliferated via IL-12 stimulation, which reportedly enhanced myocarditis [14], indicating that the BrdU cell proliferation ELISA kit is working properly (Supplementary Material Figure S6). Here, NFKB1 is linked to myocarditis.
