Online published on 2 February, 2019. Abstract Introduction Miana is one of the most widely used medicinal plants in Indonesia because its antibacterial activity, but its mechanisms not clear. This study aims to determine mRNA TLR-4 expression in Balb/c Mice induced by Salmonella typhi after miana leaf extract (MLE) treatment. Material and Method Mice were divided into four groups, antibiotic (levofoxacin eight mg/kg body weight) as positive control, placebo (Na CMC), MLE and mixed of MLE and antibiotic. Blood of the mice was taken before (H0) and after induction of 103 CFU/mL Salmonella typhi (H1) and seven days after intervention (H7). The mRNA TLR-4 expression was measured by real time PCR. The results obtained were processed using SPSS. Results There were signifcant difference in HO-Hl for all groups. TLR-4 expression in Hl-H7 had a different pattern between placebo and positive control, MLE, and the mixed of MLE and antibiotic. In placebo, there was an increase of TLR-4 expression in H1-H7). In the positive control, MLE treatment group and the mixed of MLE and antibiotic, there was a decrease in TLR-4 mRNA expression. Conclusions Miana leaves treatment in Balb/c mice induced by Salmonella typhi signifcantly gave the same effect as positive control to expression of mRNA TLR-4.
