Caveolae meet endosomes: A stable relationship?

Abstract

The endocytic trafficking of caveolae has been the subject of some controversy for many years. A new study (Pelkmans et al.) shows that budded caveolae can interact with both the caveosome and the early endosome and that caveolin-enriched regions of the early endosomal membrane form unusually stable domains that can incorporate cargo in a regulated manner.
