BMDM and major glial cells exposed to related mass doses of latex beads released far more IL-1 in response to 20 nm than 1 m size particles. In 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. Also, inflammasome activation by the 20 nm particles was related with their capacity to induce cellular harm and ATP release [89]. In dendritic cells, IL-1 release immediately after polystyrene particle exposure (mass dose) was greater in response to 430 nm and 1 m than for the ten or 32 m particles. Within this model, modest polystyrene particles had been a lot more effectively internalized in comparison with larger particles [36]. Silver nanoparticles of 5, 28 and one hundred nm were all internalized in monocytes but only five 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 having a reduced endocytosis and lysosomal harm. It’s also essential to emphasize that the compact size of nanoparticles allows them to reach intracellular compartments like mitochondria [150] or to bind proteins including actin [109]. Uncomplicated diffusion of nanomaterials across the cell membrane is often suffici.
