In the Lactobacillus casei cell-wall extract (LCWE)-induced mouse model of KD (49), but not in the murine model induced by CAWS (water-soluble extracellular polysaccharide fraction obtained from the culture supernatant of Candida albicans) (50), IL-1β and IL-1α have been shown to induce myocarditis and aneurysm formation (51, 52). Here, IL1B is linked to myocarditis.
