Lipidomic profiling of bioactive lipids by mass spectrometry during microbial infections

Bioactive lipid mediators play crucial roles in promoting the induction and resolution of inflammation. Eicosanoids and other related unsaturated fatty acids have long been known to induce inflammation. These signaling molecules can modulate the circulatory system and stimulate immune cell infiltration into the site of infection. Recently, DHA- and EPA-derived metabolites have been discovered to promote the resolution of inflammation, an active process. Not only do these molecules stop the further infiltration of immune cells, they prompt non-phlogistic phagocytosis of apoptotic neutrophils, stimulating the tissue to return to homeostasis. After the rapid release of lipid precursors from the plasma membrane upon stimulation, families of enzymes in a complex network metabolize them to produce a large array of lipid metabolites. With current advances in mass spectrometry, the entire lipidome can be accurately quantified to assess the immune response upon microbial infection. In this review, we discuss the various lipid metabolism pathways in the context of the immune response to microbial pathogens, as well as their complex network interactions. With the advancement of mass spectrometry, these approaches have also been used to characterize the lipid mediator response of macrophages and neutrophils upon immune stimulation in vitro. Lastly, we describe the recent efforts to apply systems biology approaches to dissect the role of lipid mediators during bacterial and viral infections in vivo.     

Anti-inflammatory effect of water-soluble complex of 1′-acetoxychavicol acetate with highly branched β-1,3-glucan on contact dermatitis

The anti-inflammatory effect on contact dermatitis of the water solubilized 1′-Acetoxychavicol Acetate (ACA) by complexation with β-1,3-glucan isolated form Aureobasidium pullulans black yeast is reported. It is well-known that ACA possesses a function to inhibit the activation of NF-κB by which genes encoding proinflammatory cytokines, chemokines, and growth factors are regulated. However, because ACA is quite insoluble in water, its usefulness has been extremely limited. On the other hand, a triple-helical polysaccharide β-1,3-glucan can include hydrophobic compounds into intrastrand hydrophobic cavity and solubilize poorly water-soluble compounds. In this study, solubilization of ACA by complexation with highly branched β-1,3-glucan was achieved. The effect of anti-inflammatory response of water-soluble ACA complex with β-1,3-glucan was confirmed in vitro and in vivo.

Erythromycin ameliorates renal injury via anti-inflammatory effects in experimental diabetic rats

Aims/hypothesis Recent studies have shown that the inflammatory process is involved in the pathogenesis of diabetic nephropathy. Fourteen-membered ring macrolides, including erythromycin, have anti-inflammatory, as well as antibacterial effects. The aim of this study was to investigate the renoprotective effects of erythromycin in streptozotocin (STZ)-induced diabetic rats.Methods STZ-induced diabetic rats were treated orally with erythromycin (5 mg/kg body weight) or vehicle every day for 8 weeks. To evaluate the effect of erythromycin treatment, we measured urinary albumin excretion, and examined the following in the kidney: histological changes, the expression of intercellular adhesion molecule-1 (ICAM-1), macrophage infiltration, and nuclear factor-kappa B (NF-B) activity.Results Erythromycin significantly reduced urinary albumin excretion without affecting blood glucose levels and blood pressure. Erythromycin also attenuated glomerular hypertrophy, mesangial expansion, macrophage infiltration and ICAM-1 expression in renal tissues. The expression of the gene encoding TGFB1 (also known as TGF-1), type IV collagen protein production and NF-B activity in renal tissues were increased in diabetic rats and reduced by erythromycin treatment.Conclusions/interpretation Erythromycin prevented renal injuries without changes of blood glucose levels and blood pressure in experimental diabetic rats. These results suggest that the renoprotective effects of erythromycin are based on its anti-inflammatory effect via suppression of NF-B activation. Modulation of microinflammation with erythromycin may provide a new approach for diabetic nephropathy.
