Francisella tularensis triggers Th1 just like MAIT tissue conferring security towards endemic and local disease.
In vitro, RvD1 also represses LPS-induced inflammation in RAW264.7 cells. These effects may be mainly attributed to RvD1 markedly suppressing excessive inflammatory responses via the inhibition of the TLR4-MyD88-mediated NF-κB and MAPK signalling pathways as well as enhancing antioxidation capacity via the activation of the Nrf2 pathway.

These results demonstrate that RvD1 is a promising hepatoprotective agent for the therapy of NASH.

However, whether MST4 participates in the inflammatory response to fungal infection remains unknown. Our study investigated the role and molecular mechanisms of MST4 in mice cornea and corneal epithelial cells exposed to Aspergillus fumigatus (A. fumigatus). Protein level of MST4 was detected in mice corneas and human corneal epithelial cells (HCECs) by Western blot analysis. The MST4 protein level was significantly elevated in mice corneas infected with A. fumigatus and HCECs exposed to A. fumigatus. MST4 expression was also detected in mice corneas by immunofluorescence staining. Furthermore, we found recombinant MST4 inhibited proinflammatory cytokines expressions induced by A. fumigatus at both the mRNA and protein levels in mice corneas and HCECs. To further investigate the mechanism of MST4's anti-inflammatory effect in A. fumigatus keratitis, we verified recombinant MST4 can inhibit curdlan-mediated proinflammatory cytokines production in HCECs. Surprisingly, recombinant MST4 protein downregulated A. fumigatus-induced Dectin-1 expression in both mRNA and protein levels in mice corneas. Recombinant MST4 can inhibit the mRNA expression level of Dectin-1 which was induced by curdlan in HCECs. find more MST4 can also inhibit the expression of Dectin-1 in mRNA levels increased by Dectin-1 overexpression plasmid in HCECs. Moreover, A. fumigatus or curdlan significantly induced the phosphorylation of Syk, which was consequently suppressed by recombinant MST4. Finally, recombinant MST4 promotes HCECs proliferation, which contribute to cornea wound healing. Taken together, our results provide evidences that MST4 inhibits inflammatory signaling response in A. fumigatus keratitis by downregulating Dectin-1/p-Syk pathway and simultaneously promotes HCECs proliferation.
Activation of the coagulation system has been related to disease activity in some inflammatory diseases. Here, we aimed to investigate the relationship between coagulation function and the disease activity of axial spondyloarthritis (axSpA).

This study retrospectively recruited 144 axSpA patients and 55 healthy controls. The patients were divided into an active group (Bath Ankylosing Spondylitis Disease Activity Index, BASDAI≥4) and a remission group (BASDAI<4). The coagulation, inflammatory and clinical parameters were detected. The correlations between these parameters were analyzed with Spearman's correlation analysis. Receiver operating characteristic (ROC) curve analysis was performed to compare the values of these variables in discriminating disease activity. Furthermore, binary logistic regression analysis was used to assess the risk factors for axSpA disease activity.

Fibrinogen (FIB) was increased in the axSpA group compared to healthy controls (P<0.001). Additionally, FIB and D-dimer were higher in the active group than in the remission group (P<0.05, respectively). FIB and D-dimer were positively correlated with ESR, CRP, BASDAI, Bath Ankylosing Spondylitis Functional Index (BASFI) and Bath Ankylosing Spondylitis Metrology Index (BASMI) (P<0.05, respectively). The area under the curve (AUC) of FIB was higher than that of ESR, CRP and D-dimer. The optimal cut-off value of FIB was 3.23g/L, with a specificity of 62.0% and sensitivity of 75.0%. FIB (OR=4.335, 95% CI 1.262-14.888, P=0.020) and BASFI score (OR=1.878, 95% CI 1.441-2.448, P<0.001) were independent risk factors affecting disease activity.

Activated coagulation is closely related to the disease activity of axSpA. FIB and D-dimer might be novel indicators for monitoring the disease activity of axSpA.

However, the effect of THCA for treating allergic asthma was unknown. Therefore, in the present study, the anti-asthmatic effects of THCA were studied in both in vitro and in vivo studies. In phorbol 12-myristate 13-acetate (PMA)-stimulated A549 airway epithelial cells, THCA pretreatment decreased the mRNA expression and secretion of interleukin (IL)-8, monocyte chemoattractant protein-1 (MCP-1), and intercellular adhesion molecules 1 (ICAM-1), and reduced the mRNA expression of matrix metalloproteinase 9 (MMP-9). THCA also inhibited PMA-induced protein kinase B (AKT), mitogen-activated protein kinase (MAPK) and nuclear factor kappa B (NF-κB) activation in A549 cells. In lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages, THCA pretreatment suppressed the mRNA expression of ICAM-1 and MMP-9. In addition, THCA suppressed the adhesion of EOL and A549 cells. In ovalbumin (OVA)-administered asthmatic mice, THCA exerted inhibitory activity on IL-5, IL-13, and MCP-1 in bronchoalveolar lavage fluid (BALF) and on OVA-specific immunoglobulin E (IgE) in serum. THCA attenuated the numbers of inflammatory cells in BALF and the influx of inflammatory cell in lung tissues. Furthermore, THCA downregulated the levels of inducible nitric oxide (iNOS), cyclooxygenase-2 (COX-2), and leukotriene B4 (LTB4) expression, mucus production and CREB phosphorylation as well as Penh value. These effects were accompanied by suppression of AKT, extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK), and NF-κB activation. Therefore, the results of the current study suggest that THCA may be a valuable adjuvant or therapeutic in the prevention or treatment of allergic asthma.
