Nano-SiO2

NLRP3 Inflammasome Inducer - Nanoparticles of silica dioxide

SiO2 nanoparticles (Nano-SIO2) are single particles of silica dioxide, an inorganic metal oxide, with a diameter less than 100 nm.

Nano-SiO2 was recently shown to trigger caspase-1 cleavage and IL-1β secretion in human macrophages and keratinocytes [1]. The pro-inflammatory activity of nano-SiO2 is mediated by the NLRP3 inflammasome. THP1 cells stably infectected with shRNAs against caspase-1 or NLRP3 did not secrete IL-1β in response to nano-SiO2.
