In comparison with control group, TLR2 and TLR4 mRNA expression was higher in AML patients than in healthy individuals although there was no statistically significant difference (ΔCt TLR2 0.9 ± 0.85 vs 0.82 ± 0.87 and ΔCt TLR4 0.33 ± 0.23 vs 0.29 ± 0.32). This evidence concerns the gene TLR4 and acute myeloid leukemia.
