Topical silver and gold nanoparticles complexed with Cornus mas suppress inflammation in human psoriasis plaques by inhibiting NF-κB activity.
Experimental Dermatology 2018 June 16
New biomaterials based on nanoparticles (NPs) carrying polyphenols-rich extracts (Cornus mas) recently showed promising anti-inflammatory activity in psoriasis. We aimed to understand how topically delivered silver and gold nanoparticles complexed with Cornus mas (Ag-NPs-CM, Au-NPs-CM) modulate inflammation in psoriasis at cellular and molecular level. The impact on psoriatic inflammation was assessed in vitro on pro-inflammatory macrophages, by clinical score, high-frequency ultrasonography and immunohistology of psoriasis plaques treated with Ag-NPs-CM, Au-NPs-CM or control. Incubation of pro-inflammatory macrophages with nanoparticles significantly decreased the release of NO, IL-12 and TNF-α. Immunofluorescence confirmed that nanoparticles significantly reduced CD68-positive macrophages and their IL-12 and TNF-α production in human psoriasis plaques. NPs-CM appear to repress NF-κB activation in macrophages, inhibiting the production of pro-inflammatory factors with causal role in psoriasis. Ag and Au NPs-CM represent a novel nanoparticle-based "green" technology which may provide an efficient tool for modern psoriasis therapy, circumventing immunosuppression-related side effects of biologicals.
