Fabrication and characterization of cuminaldehyde-loaded electrospun gliadin fiber mats

This work's objective was to develop a novel type of gliadin electrospun fiber with antibacterial properties by incorporating cuminaldehyde in the fibrous structure. Gliadin fibers containing various concentrations of cuminaldehyde were fabricated via an e ...

Chapter 6: Production and Applications of Polyunsaturated Fatty Acids

Edgard Gnansounou, Binod Parameswaran, Ummalyma Sabeela Beevi

Polyunsaturated fatty acids (PUFAs) are key molecules for the control of human as well as animal health. Among the PUFAs, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are vital compounds for infant brain development and other immune regulator ...

A Click Cage: Organelle‐Specific Uncaging of Lipid Messengers

Lipid messengers exert their function on short time scales at distinct subcellular locations, yet most experimental approaches for perturbing their levels trigger cell-wide concentration changes. Herein, we report on a coumarin-based photocaging group that ...

Dysregulation of soluble epoxide hydrolase and lipidomic profiles in anorexia nervosa

Pierre Magistretti, Jiangyan Yang

Individuals with anorexia nervosa (AN) restrict eating and become emaciated. They tend to have an aversion to foods rich in fat. Because epoxide hydrolase 2 (EPHX2) was identified as a novel AN susceptibility gene, and because its protein product, soluble ...

A benthic foraminifera species respond to anoxia with a strong metabolic shift suggesting a state of dormancy

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Low-oxygenation events are more and more frequent and strong on continental shelves and in coastal areas where renewal of bottom waters is slow. Among the meiofauna living in such environments, foraminifera are among the most tolerant to the lack of oxygen ...

LRH-1 mediates anti-inflammatory and antifungal phenotype of IL-13-activated macrophages through the PPAR gamma ligand synthesis

Kristina Schoonjans, Matthias Alexander Sokrates Stein

Liver receptor homologue-1 (LRH-1) is a nuclear receptor involved in the repression of inflammatory processes in the hepatointestinal tract. Here we report that LRH-1 is expressed in macrophages and induced by the Th2 cytokine IL-13 via a mechanism involvi ...

Metabolic modeling and experimental studies on carbon and energy metabolism of Mycobacterium tuberculosis

Muhittin Emre Özdemir

Tuberculosis is an ancient human disease affecting millions of people every year. The common causative agent, Mycobacterium tuberculosis, is a peculiar pathogen that can persist in the host tissues for decades. Many of the key attributes of M. tuberculosis ...

The C-type Lectin Receptors Dectin-1, MR, and SIGNR3 Contribute Both Positively and Negatively to the Macrophage Response to Leishmania infantum

Johan Auwerx

Macrophages act as the primary effector cells during Leishmania infection through production of reactive oxygen species (ROS) and interleukin-1 beta (IL-1 beta). However, how macrophage-killing mechanisms are activated during Leishmania-macrophage interact ...

Real-Time Noninvasive Imaging of Fatty Acid Uptake in Vivo

Gennady Nikitin

Detection and quantification of fatty acid fluxes in animal model systems following physiological, pathological, or pharmacological challenges is key to our understanding of complex metabolic networks as these macronutrients also activate transcription fac ...

Structure-activity relationship study of betulinic acid, a novel and selective TGR5 agonist, and its synthetic derivatives: potential impact in diabetes

Johan Auwerx, Kristina Schoonjans

We describe here the biological screening of a collection of natural occurring triterpenoids against the G protein-coupled receptor TGR5, known to be activated by bile acids and which mediates some important cell functions. This work revealed that betulini ...
