Tiopronin Monolayer-Protected Silver Nanoparticles Modulate IL-6 Secretion Mediated by Toll-Like Receptor Ligands

Abstract

Contrary to what is found for bare silver nanoparticles, Ag@tiopronin nanoparticles are noncytotoxic to macrophages. Ag@tiopronin nanoparticles showed differential effects on TLR signaling of a high degree of specificity, without proinflammatory effects by themselves. These effects have to be borne in mind when using bioconjugates of Ag@tiopronin nanoparticles for future medical applications.
