Mechanisms of outer membrane vesicle entry into host cells
Bacterial outer membrane vesicles (OMVs) are nano-sized compartments consisting of a lipid bilayer that encapsulates periplasm-derived, luminal content. OMVs, which pinch off of Gram-negative bacteria, are now recognized as a generalized secretion pathway which provides a means to transfer cargo to other bacterial cells as well as eukaryotic cells. Compared with other secretion systems, OMVs ca...
متن کاملTrypanosoma cruzi: Entry into Mammalian Host Cells and Parasitophorous Vacuole Formation
Trypanosoma cruzi, the causative agent of Chagas disease, is transmitted to vertebrate hosts by blood-sucking insects. This protozoan is an obligate intracellular parasite. The infective forms of the parasite are the metacyclic trypomastigotes, amastigotes, and bloodstream trypomastigotes. The recognition between the parasite and mammalian host cell, involves numerous molecules present in both ...
متن کاملPathway for polyarginine entry into mammalian cells.
Cationic peptides known as protein transduction domains (PTDs) provide a means to deliver molecules into mammalian cells. Here, nonaarginine (R(9)), the most efficacious of known PTDs, is used to elucidate the pathway for PTD internalization. Although R(9) is found in the cytosol as well as the nucleolus when cells are fixed, this peptide is observed only in the endocytic vesicles of live cells...
متن کاملTAT-mediated protein transduction into mammalian cells.
Manipulation of mammalian cells has been achieved by the transfection of expression vectors, microinjection, or diffusion of peptidyl mimetics. While these approaches have been somewhat successful, the classic manipulation methods are not easily regulated and can be laborious. One approach to circumvent these problems is the use of HIV TAT-mediated protein transduction. Although this technology...
متن کاملThe transport of glutamine into mammalian cells.
Glutamine has many important functions in mammalian cells, and glutamine transport across cell membranes has accordingly been extensively studied. In the past few years a number of important glutamine transport proteins have been sequenced and their molecular properties have been characterised. In general, four major transporters are important physiologically. These are known as (i) SNAT3 (Syst...
