Besides IFNAR1, expression of IFN pathway genes in PMN was upregulated in pregnant but not in non-pregnant comfort group cows on Days 14 and 18 (P0.05; Fig 4AF). Having said that, expression of all evaluated IFN pathway genes was not different amongst pregnant and non-pregnant cows below heat pressure (Fig 4GL).ISGs and IFN pathway expression in PMN of pregnant cows in comfort or below heat strain environmentFor the objective of identifying variations in pregnant cows, relative mRNA
