Network pharmacological prediction and experimental validation of Xijiao Dihuang Decoction combined with Yinqiao Powder in macrophages infected with influenza virus
We aimed to explore the anti-inflammatory molecular mechanism of
Xijiao Dihuang
Decoction combined with
Yinqiao
Powder(XDY) in macrophages infected with influenza virus.
Methods
2
Genes related to human macrophages infected by influenza virus PR8 were screened by the gene chip published in the GEO database.The intersection of the active components of XDY and the related differential genes of human macrophages infected by influenza virus PR8 was input into the STRING database to obtain the interaction relationship between target proteins.The core target was obtained according to the degree of protein interaction.The protein-protein interaction network was visualized with Cytoscape 3.7.2 software
and topology analysis was performed.The Metascape database was used for Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis.Macrophages J774A.1 were divided into the normal group
the model group(influenza virus PR8 infection)
and the XDY group(PR8 + 162.5 mg/L XDY) and treated for 24 h. The mRNA levels of Toll-like receptor 4(TLR4)
myeloid differentiation factor 88(MyD88)
TNF receptor-associated factor 6(TRAF6)
tumor necrosis factor-α(TNF-α)
and interleukin-6(IL-6) were detected by real-time PCR; nuclear factor-κB(NF-κB) translocation was detected by immunofluorescence; and the levels of TNF-α and IL-6 in the supernatant were detected by ELISA.
Results
2
In total
104 common targets were obtained by analyzing the intersection of the differentially expressed genes in the PR8 and XDY groups.Pathway enrichment analysis showed that the effects of XDY on influenza may be mediated by the TLR4/NF-κB pathway.PCR result showed that compared with the model group
the mRNA levels of TLR4
MyD88
TRAF6
TNF-α
and IL-6 were lower in the XDY group(
P
<
0.01).Immunofluorescence result showed that compared with the model group
the nuclear localization of NF-κB in the XDY group was decreased
and the nuclear-cytoplasmic ratio was also decreased(
P
<
0.01).ELISA result showed that compared with the model group
the levels of TNF-α and IL-6 in the supernatant in the XDY group were decreased(
P
<
0.01).
Conclusion
2
Xijiao Dihuang
Decoction combined with
Yinqiao
Powder can regulate the TLR4/NF-κB pathway to reduce the inflammatory response in macrophages infected with influenza virus.
