Metabololipidomic profiling of functional immunoresolvent clusters and eicosanoids in mammalian tissues.

Metabolomics enables a systems approach to interrogate the bioactive mediators, their pathways and further metabolites involved in the physiology and pathophysiology of human and animal tissues. New metabololipidomic approaches with mass spectrometry presented in this brief review can now be utilized for the identification and profiling of lipid mediator networks that control inflammation-resolution in human blood and healthy and diseased solid tissues. Coagulation of blood is a protective response that pre...


Gamma-tocotrienol attenuates the aberrant lipid mediator production in NLRP3 inflammasome-stimulated macrophages.

The activation of NLRP3 inflammasome in innate immune cells is associated with enhanced production of pro-inflammatory lipid mediator eicosanoids that play a crucial role in propagating inflammation. Gamma-tocotrienol (γT3) is an unsaturated vitamin E that has been demonstrated to attenuate NLRP3-inflammasome. However, the role of γT3 in regulating eicosanoid formation is unknown. We hypothesized that γT3 abolishes the eicosanoid production by modulating the macrophage lipidome. LPS-primed bone marrow-de...

Bioactive lipid species and metabolic pathways in progression and resolution of Non-Alcoholic Steatohepatitis.

The prevalence of non-alcoholic steatohepatitis (NASH) is increasing worldwide, yet there are no effective treatments. A decade has passed since initial lipidomic analyses of liver tissues from patients with non-alcoholic fatty liver disease. We have learned that liver cells from patients with NASH have an abnormal lipid composition, and the accumulation of lipids leads to organelle dysfunction, cell injury and death, and chronic inflammation, called liptoxicity. We review the lipid species and metabolic pa...


Antenna-Enhanced Fluorescence Correlation Spectroscopy Resolves Calcium-Mediated Lipid-Lipid-Interactions.

Fluorescence correlation spectroscopy (FCS) has provided a wealth of information on the composition, structure, and dynamics of cell membranes. However, it has proved challenging to reach the spatial resolution required to resolve biophysical interactions at the nm-scale relevant to many crucial membrane processes. In this work, we form artificial cell membranes on dimeric, nanoplasmonic antennas, which shrink the FCS probe volume down to the ~20 nm length-scale. By analysing the autocorrelation functions (...

Sparsity-based super-resolution microscopy from correlation information.

For more than a century, the wavelength of light was considered to be a fundamental limit on the spatial resolution of optical imaging. Particularly in light microscopy, this limit, known as Abbe's diffraction limit, places a fundamental constraint on the ability to image sub-cellular organelles with high resolution. However, modern microscopy techniques such as STED, PALM, and STORM, manage to recover sub-wavelength information, by relying on fluorescence imaging. Specifically, PALM/STORM acquire large seq...

Unified nexus of macrophages and maresins in cardiac reparative mechanisms.

Macrophages are immune-sensing "big eater" phagocytic cells responsible for an innate, adaptive, and regenerative response. After myocardial infarction, macrophages predominantly clear the deceased cardiomyocyte apoptotic or necrotic neutrophils to develop a regenerative and reparative program with the activation of the lipoxygenase-mediated maresin (MaR) metabolome at the site of ischemic injury. The specialized proresolving molecule and macrophage mediator in resolving inflammation, MaR-1, produced by hum...

Oral ibuprofen differentially affects plasma and sweat lipid mediator profiles in healthy adult males.

Sweat contains a variety of lipid mediators, but whether they originate from the plasma filtrate or from the cutaneous sweat glandular tissues themselves is unknown. To explore this knowledge gap, we collected plasma and sweat from healthy men (n = 9) immediately before and 0.5, 2 and 4 h after oral administration of 400 mg ibuprofen. Of the over 100 lipid mediators assayed by liquid chromatography-tandem mass spectrometry, ~45 were detected in both plasma and sweat, and 36 were common to both matri...

Eicosanoid signaling in carcinogenesis of colorectal cancer.

Colorectal cancer (CRC) is the third most common cancer and the second leading cause of cancer-related death in the USA. It is of practical importance to identify novel therapeutic targets of CRC to develop new anti-cancer drugs and to discover novel biomarkers of CRC to develop new detection methods. Eicosanoids, which are metabolites of polyunsaturated fatty acids produced by cyclooxygenase (COX), lipoxygenase (LOX), and cytochrome P450 (CYP) enzymes, are important lipid-signaling molecules involved in th...

Resolution of fatty liver and weight loss: Independent associations with changes in serum lipids and apolipoproteins.

It is uncertain whether resolution of fatty liver can improve cardiovascular disease risk factors, independently of changes in body mass index (BMI). Our aim was to test whether resolution of fatty liver is associated with improvements in components of the lipid profile, independently of changes in BMI, and to quantify and compare the magnitude of benefit of resolution of liver fat, and decreases in BMI on the lipid profile.

Dexamethasone induces ω3-derived immunoresolvents driving resolution of allergic airway inflammation.

Dexamethasone induces the production of DHA-derived specialized proresolving lipids and the resolution of allergic airway inflammation. This adds glucocorticosteroids to the short list of drugs that are known to possess direct pro-resolving functions.

Association between lipid profiles and osteoporosis in postmenopausal women: a meta-analysis.

To investigate the relationship between blood lipid profiles and osteoporosis in postmenopausal women.

New maresin conjugates in tissue regeneration pathway counters leukotriene D-stimulated vascular responses.

Resolution of acute inflammation is governed, in part, by lipid mediator class switching from proinflammatory eicosanoids to specialized proresolving mediators, including a recently identified new pathway of mediators, termed maresin conjugates in tissue regeneration (MCTR), which includes MCTR1, MCTR2, and MCTR3. Here, we addressed whether each MCTR can impact the known vascular actions of cysteinyl leukotrienes. Leukotriene D(LTD; 1.5 nmol/mouse) initiated vascular leakage in mouse cremaster vessels, whic...

Influence of dietary vegetable oil blend on serum lipid profiles in large yellow croaker (Larimichthys crocea).

Serum lipid metabolic responses are associated with certain metabolic disorders induced by dietary habit in mammals. However, such associations have not been reported in fish. Lipidomic analyses were performed to investigate fish lipid metabolic responses for dietary vegetable oil (VO) blend, and to elucidate the mechanism of how dietary VO blend affects serum lipid profiles. Results showed that dietary VO blend strongly affects serum lipid profiles, especially ratio of triglyceride:phosphatidylcholine (TAG...

Serum Lipid Concentrations and FADS Genetic Variants in Young Mexican College Students: The UP-AMIGOS Cohort Study.

Recent genome-wide association studies in the Mexican population have identified several genetic loci associated with blood lipid levels in adults. However, studies focusing on the fatty acid desaturase (FADS) gene cluster have been understudied in this population, even though it seems associated with lipid profiles in other ethnicities. The aim of this study was to test associations between single nucleotide polymorphisms (SNPs) in the FADS cluster (rs174546, rs1535, rs174548, rs174550, rs174450, and rs174...

Temporal Multivariate Pattern Analysis (tMVPA): a single trial approach exploring the temporal dynamics of the BOLD signal.

fMRI provides spatial resolution that is unmatched by non-invasive neuroimaging techniques. Its temporal dynamics however are typically neglected due to the sluggishness of the hemodynamic signal.

Resolvin D1 blocks H2O2-mediated inhibitory crosstalk between SHP2 and PP2A and suppresses endothelial-monocyte interactions.

In recent years, various studies have demonstrated a role for endogenously derived specialized proresolving mediators such as resolvins in the resolution of inflammation. In exploring the signaling mechanisms, in the present study we show that Resolvin D1 (RvD1) reduces LPS-induced endothelial cell (EC)-monocyte interactions via blocking H2O2-mediated PP2A inactivation, NFκB activation and ICAM1 and VCAM1 expression. In addition, we found that H2O2-mediated SHP2 inhibition leads to tyrosine phosphorylation...

Towards targeting resolution pathways of airway inflammation in asthma.

Asthma is a chronic disorder characterized by persistent inflammation of the airways with mucosal infiltration of eosinophils, T lymphocytes, and mast cells, and release of proinflammatory cytokines and lipid mediators. The natural resolution of airway inflammation is now recognized as an active host response, with highly coordinated cellular events under the control of endogenous pro-resolving mediators that enable the restoration of tissue homeostasis. Lead members of proresolving mediators are enzymatica...

The objective of this study was to investigate the relationship between serum lipid concentrations and PTSD symptoms in the bereaved after a traumatic familial loss. Eighteen months after the Sewol ferry disaster, 107 subjects who experienced traumatic losses as a result of the accident completed a mental and medical survey as well as laboratory tests for lipid profiles. At 30 months after the trauma, a total of 64 individuals completed a follow-up psychometric survey and biochemical measurements. We perfor...

High Spatial-temporal Resolution Reconstruction of Plane-wave Ultrasound Images with a Multichannel Multiscale Convolutional Neural Network.

In recent years, plane-wave imaging (PWI) has attracted considerable attention because of its high temporal resolution. However, the low spatial resolution of PWI limits its clinical applications, which has inspired various studies on the high spatial resolution reconstruction of plane-wave (PW) ultrasound images. Although compounding methods and traditional high spatial resolution reconstruction approaches can improve the image quality, these techniques decrease the temporal resolution. Since learning meth...

Super-temporal resolved microscopy reveals multistep desorption kinetics of α-lactalbumin from nylon.

Insight into the mechanisms driving protein-polymer interactions is constantly improving due to advances in experimental and computational methods. In this work, we used super-temporal resolved microscopy (STReM) to study the interfacial kinetics of a globular protein, α-lactalbumin (α-LA), adsorbing at the water-nylon 6,6 interface. The improved temporal resolution of STReM revealed that residence time distributions involve an additional step in the desorption process. Increasing the ionic strength in th...

Damage of the temporal lobe and APOE status determine neural compensation in mild cognitive impairment.

In mild cognitive impairment (MCI), the APOE4 genotype is associated with accelerated memory decline, likely due to the impact of neuropathology on main cerebral networks required for successful memory retrieval and/or to decreased capacity for recruiting secondary networks that might compensate for that brain damage. Here, we tested this hypothesis in twenty-six healthy older adults and thirty-four MCI patients, of which sixteen were APOE4 carriers. Compared to controls, MCI showed hippocampal volume reduc...

Clinical correlation of biopsy results in patients with temporal arteritis.

Temporal arteritis is systemic vasculitis of medium and large sized vessels. The lowest incidence rates were reported in Turkey, Japan and Israel. We aimed to investigate the results of patients with biopsy-proven temporal arteritis and those classified according to the American College of Rheumatology criteria from a low-incidence region for temporal arteritis. The results of our study are noteworthy, since there is limited data on pathologic diagnosis of temporal arteritis in Turkey.

Age- and sex-related differences of lipid profiles were not well understood among ischemic stroke patients in China. Our study aimed to investigate the relationship between lipid abnormalities and ischemic stroke in China. A retrospective analysis was performed involving 2074 patients with ischemic stroke who admitted to Meizhou People's Hospital (Huangtang Hospital), Meizhou Hospital Affiliated to Sun Yat-sen University between January 1, 2014 and March 1, 2017. Our study indicated that there were signific...

Increased brain docosahexaenoic acid has no effect on the resolution of neuroinflammation following intracerebroventricular lipopolysaccharide injection.

Resolution of inflammation in the periphery was once thought to be a passive process, but new research now suggests it is an active process mediated by specialized pro-resolving lipid mediators (SPM) derived from omega-3 polyunsaturated fatty acids (n-3 PUFA). However, this has yet to be illustrated in neuroinflammation. The purpose of this study was to measure resolution of neuroinflammation and to test whether increasing brain docosahexaenoic acid (DHA) affects the resolution of neuroinflammation. C57Bl/6...

Bias-Exchange Metadynamics Simulation of Membrane Permeation of 20 Amino Acids.

Thermodynamics of the permeation of amino acids from water to lipid bilayers is an important first step for understanding the mechanism of cell-permeating peptides and the thermodynamics of membrane protein structure and stability. In this work, we employed bias-exchange metadynamics simulations to simulate the membrane permeation of all 20 amino acids from water to the center of a dipalmitoylphosphatidylcholine (DPPC) membrane (consists of 256 lipids) by using both directional and torsion angles for confor...
