Nanoscale outer membrane vesicles (OMVs) secreted by Gram-negative bacteria are often applied in antibacterial treatment as adjuvants or antigens. Recently, OMVs have also been tested a few anti-tumor studies, which injected multiple times to achieve certain therapeutic effects, showing risks repeated cytokine storms. Herein, we propose the use single low dose of combined with photothermal ther...

UNLABELLED The outer membrane (OM) of Gram-negative bacteria provides protection against toxic molecules, including reactive oxygen species (ROS). Decreased OM permeability can promote bacterial survival under harsh circumstances and protects against antibiotics. To better understand the regulation of OM permeability, we studied the real-time influx of hydrogen peroxide in Salmonella bacteria a...

Infection of host cells by Salmonella enterica serovar Typhimurium (S. typhimurium) leads to the formation of specialised membrane-bound compartments called Salmonella-containing vacuoles (SCVs). Bacteria remain enclosed by the vacuolar membrane as they divide, and by translocating effector proteins across the vacuolar membrane through the SPI-2 type III secretion system, they interfere with ho...

Bacteria of the phylum Planctomycetes are of special interest for the study of compartmental cellular organization. Members of this phylum share a very unusual prokaryotic cell plan, featuring several membrane-bound compartments. Recently, it was shown that this cellular organization might extend to certain members of the phylum Verrucomicrobia. The Planctomycete cell plan has been defined as f...
