Extended Data Fig. 10: Model of Siglec-14-mediated pro-inflammatory responses to MWCNTs and SWCNTs.
From: Carbon nanotube recognition by human Siglec-14 provokes inflammation

a, Upon MWCNT recognition, Siglec-14 transmits activation signals leading to phagocytosis and IL-8 induction. Phagocytosed MWCNTs cause phagosomal rupture, resulting in NLRP3 inflammasome activation and caspase-1 activation leading to IL-1β secretion. b, Upon SWCNT recognition, Siglec-14 transmits activation signals leading to phagocytosis and IL-8 induction. Since phagocytosed SWCNTs do not cause phagosomal rupture, IL-1β is not secreted. Figure was drawn with BioRender.com.
