abstract：:ARF GTPases act at multiple steps of the secretory and vacuolar/lysosomal trafficking pathways, but little is known about the spatial regulation of ARF activation. In this issue of Cell, Geldner et al. demonstrate that the Arabidopsis ARF activator GNOM localizes to endosomes where it controls the polarized traffickin...

abstract：:MiRNAs are regulatory molecules that can be packaged into exosomes and secreted from cells. Here, we show that adipose tissue macrophages (ATMs) in obese mice secrete miRNA-containing exosomes (Exos), which cause glucose intolerance and insulin resistance when administered to lean mice. Conversely, ATM Exos obtained f...
