Zusammenfassung

Phylogenomic data suggests that eukaryotes arose by symbiosis between an archaeal cell and a bacterial partner. However, this does little to explain the origins of the elaborate membrane and vesicle trafficking systems that underpin eukaryotic cell organization, since the closest living relatives of these two partners that can currently be studied at the cellular level (TACK family archaea and alpha-proteobacteria) lack internal membranes. Nevertheless, TACK archaea, such as Sulfolobus, generate exosomes, extracellular vesicles. The generation and scission of exosomes in those archaea ...
