Protein expression of the GATA6-dependent gene CD73 by LCMs matched our sequencing data,12 with LCMs from C57BL/6 mice having higher expression than BALB/c mice and infection leading to a further increase in CD73 expression in C57BL/6 LCMs but a complete loss in BALB/c mice (Figure 5C). Here, GATA6 is linked to infection.
