Extended Data Fig. 5: Expression of Ifih1, Ifnb1, and Apaf1 in MerTK+ cardiac macrophage.

a–c. Representative IF images and quantification of IFIH1+MerTK+ (a), IFNB1+MerTK+ (b) and APAF1+MerTK+ (c) cells in cardiac ischemic regions of WT and ATF3-CKO mice post-IR. Percentage of double positive cells in total MerTK+ cells per HPF (n = 6 mice per group). Statistical significance was evaluated using two-tailed unpaired t tests (a–c). All data are presented as mean ± SEM.
