Using a similar labeling and gating strategy published by Monsivaís-Urenda [28], we analyzed the percentage of ILT2 and ILT4 positive cells in myeloid dendritic cells defined as LINnegHLA − DR + CD11c + BDCA1+ and plasmacytoid dendritic cells defined as LINnegHLA − DR + CD11c − BDCA4+ in circulating dendritic cells from myocarditis patients (Figure 3(a)) and healthy controls (Figure 3(b)). Here, LILRB2 is linked to myocarditis.
