A brief guide to studying extracellular vesicle function in the context of metabolism - Nature Metabolism Extracellular vesicles (EVs) are now recognized as powerful modulators of metabolism, and thus the new field of EV-mediated metabolic regulation is growing exponentially. Here, we discuss special experimental considerations for the study of EV function in metabolism.

Metabolites are not genes — avoiding the misuse of pathway analysis in metabolomics - Nature Metabolism Pathway analysis, originally developed for gene expression data, has been adapted for metabolomics. However, owing to the unique characteristics and constraints of metabolites compared with genes, pathway analysis in metabolomics often yields misleading or nonsensical results.

Allergen-induced airway matrix remodeling in mice can be prevented or reversed by targeting chitinase-like proteins Allergic airway matrix remodeling occurs independently of IL-13 and IL-17A and is driven instead by chitinase-like proteins.

Extremely happy to see our work out in #ScienceImmunology. We show allergen-induced ECM remodelling occurs independently of IL-13 or IL-17 driven inflammation. Rather chitinase-like proteins drive airway ECM accumulation & inhibition of Ym1 can remarkably reverse it. www.science.org/doi/10.1126/...

'Here, we identify the immunometabolic crosstalk that generates homocysitaconate, a metabolite formed by homocysteine & itaconate adduction catalyzed by S-adenosyl-L-homocysteine hydrolase. Homocysitaconate increases 152-fold during #inflammation and exhibits anti-inflammatory effects.'

Signalling from adipose tissue to the brain is not just about leptin - Nature Metabolism A Nature Metabolism study shows that, under acute stress, fatty acids liberated by lipolysis of white fat cells cause release from local macrophages of the growth-differentiation factor GDF15, which, in turn, binds to the receptor GFRAL in the brain, evoking anxiety.
