Formation of intracellular vesicles within the Gram Lactococcus lactis induced by the overexpression of Caveolin-1β.

Background: Caveolae are invaginated plasma membrane domains of 50-100 nm in diameter involved in many important physiological functions in eukaryotic cells. They are composed of different proteins, including the membrane-embedded caveolins and the peripheric cavins. Caveolin-1 has already been expressed in various expression systems (E.
