STAT3 and mastitis: In both S. aureus-positive and S. chromogenes-positive cows, the DE snoRNAs were correlated with several immune and inflammatory genes (e.g., IL1R, IL18R1, STAT3, NFKB2, MYD88, VEGFA and CD40), all of which have been reported in several studies to be associated to mastitis [47–53].
