Barringtonia augusta methanol extract (Ba-ME) is a folk medicine found in the wetlands of Thailand that acts through an anti-inflammatory mechanism that is not understood fully. Here, we examine how the methanol extract of Barringtonia augusta (B. augusta) can suppress the activator protein 1 (AP-1) signaling pathway and study the activities of Ba-ME in the lipopolysaccharide (LPS)-treated RAW264.7 macrophage cell line and an LPS-induced peritonitis mouse model. Non-toxic concentrations of Ba-ME downregulated the mRNA expression of cytokines, such as cyclooxygenase and chemokine ligand 12, in LPS-stimulated RAW264.7 cells. Transfection experiments with the AP-1-Luc construct, HEK293T cells, and luciferase assays were used to assess whether Ba-ME suppressed the AP-1 functional activation. A Western blot assay confirmed that C-Jun N-terminal kinase is a direct pharmacological target of Ba-ME action. The anti-inflammatory effect of Ba-ME, which functions by β-activated kinase 1 (TAK1) inhibition, was confirmed by using an overexpression strategy and a cellular thermal shift assay. In vivo experiments in a mouse model of LPS-induced peritonitis showed the anti-inflammatory effect of Ba-ME on LPS-stimulated macrophages and acute inflammatory mouse models. We conclude that Ba-ME is a promising anti-inflammatory drug targeting TAK1 in the AP-1 pathway.

The instillation of Escherichia coli endotoxin (lipopolysaccharide) intranasally into mice produced severe lung lesions and a substantial increase in lung weight. Lung inflammation was maximal about 3 days after endotoxin instillation. Intraperitoneal injection of prednisone, cortisone and hydrocortisone sharply suppressed the lung inflammation. Five milligrams of prednisone produced a maximal anti-inflammatory effect when injected 24 and 48 hours after the endotoxin. Administration of large doses of Butazolidin also produced a modest effect on the lung inflammation. It is suggested that locally applied endotoxin alters blood vessel permeability of the lungs, resulting in hemorrhage, edema and exudation. The anti-inflammatory steroids reverse or inhibit this effect, perhaps by maintaining the integrity of the capillaries. Possible use and significance of this experimental anti-inflammatory system is discussed.

The aim of the present study was to determine the anti-inflammatory effect of IFN-τon endometritis using a mouse model ofS. aureus-induced endometritis and to elucidate the mechanism of action underlying these effects. In the present study, the effect of IFN-τonS. aureusgrowth was monitored by turbidimeter at 600 nm. IFN-τdid not affectS. aureusgrowth. The histopathological changes indicated that IFN-τhad a protective effect on uterus tissues withS. aureusinfection. The ELISA and qPCR results showed the production of the proinflammatory cytokines TNF-α, IL-1β, and IL-6 was decreased with IFN-τtreatment. In contrast, the level of the anti-inflammatory cytokine IL-10 was increased. We further studied the signaling pathway associated with these observations, and the qPCR results showed that the expression of TLR2 was repressed by IFN-τ. Furthermore, the western blotting results showed the phosphorylation of IκB, NF-κB p65, and MAPKs (p38, JNK, and ERK) was inhibited by IFN-τtreatment. The results suggested that IFN-τmay be a potential drug for the treatment of uterine infection due toS. aureusor other infectious inflammatory diseases.
