AbstractSingle walled carbon nanotubes (SWCNTs) have been shown to be highly effective against a wide range of bacteria. Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) infection is a well-known mediator to prolong hospitalization and initiate chronic inflammation, yet the biological effects of SWCNTs on the pathogen-infected enterocytes remain unclear. Herein, it is shown that the low-dose SWCNT treatment attenuates the human enterocyte-like Caco-2 cells from the damage of E. coli and S. aureus infection by suppressing NLRP3 inflammasome activation. The relatively low-dose (1 and 10 mu g mL(-1)) SWCNT treatments reduce the adhesion and invasion of E. coli and S. aureus to Caco-2 cells, increase the cell viability and proliferation, reduce the tight junction permeability, and restitute the integrity of cell surface microvilli structure, meanwhile has low cytotoxicity to the host cells. The low-dose SWCNT treatment further reduces the NLRP3-mediated IL-1 beta secretion in the infected cells. The results identify that a low-dose SWCNT treatment serves a protective function for the E. coli- and S. aureus-infected Caco-2 cells by negatively regulating mitochondrial reactive oxygen species-mediated NLRP3 inflammasome activation.
