BMDM and major glial cells exposed to related mass doses of latex beads released much more IL-1 in response to 20 nm than 1 m size particles. Within this study, inflammasome activation was attributed to lysosomal destabilization and cathepsin B release for 20 nm particles and to ROS production and mitochondrial damage for 1 m particles. Moreover, inflammasome activation by the 20 nm particles was linked with their capacity to induce cellular harm and ATP release [89]. In dendritic cells, IL-1 release right after polystyrene particle exposure (mass dose) was greater in response to 430 nm and 1 m than to the ten or 32 m particles. Within this model, smaller polystyrene particles had been much more efficiently internalized in comparison with larger particles [36]. Silver Neocarzinostatin Cancer nanoparticles of 5, 28 and 100 nm have been all internalized in monocytes but only 5 and 28 nm induced vesicular damage with ROS production and IL-1 release [116]. The reasonably low capacity of micrometricparticles to activate the inflammasome seems connected with a reduce endocytosis and lysosomal damage. It is also significant to emphasize that the small size of nanoparticles makes it possible for them to attain intracellular compartments like mitochondria [150] or to bind proteins like actin [109]. Basic diffusion of nanomaterials across the cell membrane may be suffici.
