Although sporadic CD45+ leukocytes (Figure 6F,G), F4/80+ macrophages (Figure 6H,I), and apoptotic cells (Figure 6J,K) were observed in the uteruses of HEV-infected pregnant mice, the number of positive cells in these groups of mice were significantly lower than that in HEV-infected mice that had experienced miscarriages (Figure 6G,I,K). Here, PTPRC is linked to spontaneous abortion.
