^a-cDifferent letters represent significant differences between treatments (P < 0.05)
The letter a indicates higher transcript levels than b and c. The letter b indicates higher transcript levels than c
^dTreatments: Control = incubation without toxins; LPS = incubation with 1 μg/mL lipopolysaccharide; LTA = incubation with 20 μg/mL lipoteichoic acid; L + L = incubation with the combination of both toxins
^y-zDifferent letters represent significant differences between time points (P < 0.05). The letter y indicates higher transcript levels than z
