TLR2 activation by (A) TLR1/TLR2 agonist Pam3CSK4 (100 ng/mL) and (B) TLR2/TLR6 agonist LTA (10 μg/mL) was examined under anesthetics (isoflurane, sevoflurane, dexmedetomidine or propofol) in THP-1 blue cell system. Data were shown as mean +/− S.D. 8 independent replicates were used per group. Statistical analysis was performed using Kruskal-Wallis test with Dunns post hoc analysis. *, ** and *** adjusted p< 0.05, < 0.01, and < 0.001 vs samples stimulated with TLR2 ligands and without anesthetics. n.s = not significant.
