Bone-to-brain crosstalkBone-derived sclerostin accelerates the progression of Alzheimer’s disease (AD) by deregulating the Wnt–β-catenin signalling pathway in the brain. The image is a staining of the enzyme β-secretase (essential for AD pathogenesis) in a hippocampus section from a mouse model of AD.

Insulin sparklesUsing a zinc-based fluorophore with spinning-disc confocal microscopy, Peng et al. visualize insulin secretion in intact mouse islets, thereby revealing a subpopulation of β cells that make a disproportionally large contribute to overall insulin release. Each coloured dot indicates an exocytosis event against the backdrop of stained β cells of a mouse islet.

FASN cuts stressIn this issue of Nature Metabolism, Wei et al. identify a non-fatty acid synthesis function for FASN in suppressing diverse aspects of stress responses through a mechanism that involves FASN cleavage. Depicted are anesthetized C. elegans following stressful conditions.
