Abstract:Antiphospholipid
syndrome (APS) is an autoimmune disease characterized
by recurrent arterial, venous, and microvascular thrombosis where
activated neutrophils play a determinant role. However, neutrophils
are challenging to target given their short lifespan in circulation
and spontaneous activation. Screening of a small library of gold nanoparticles
(AuNPs) led to the discovery of a formulation capable of targeting
activated neutrophil attachment and has demonstrated that star-shaped,
anti-PSGL-1-antibody-coa… Show more
“…19 In addition, gold nanoparticles can also target activated neutrophil attachment to treat immunothrombosis associated with neutrophil adhesion in antiphospholipid syndrome. 20 Compared with gold nanoparticles, ultrasmall AuNCs have distinctive physicochemical properties and biological behaviors. 21 For example, 6-mercaptohexanoic acid-capped AuNCs have potent antibacterial activity, while their large-sized counterparts are inactive.…”
Here we report for the first time that mercaptopyrimidine-templated gold nanoclusters (DAMP-AuNCs) can be used as a novel anticoagulant candidate for the design of antithrombotic drugs. Anticoagulant mechanisms revealed that...
