Naïve and pro-inflammatory activated macrophage cultures were treated with silver and gold nanoparticles at 1:10 and 1:100 dilutions. 2012, 61, 1177.Įxd1370-SupInfo.docWord document, 63.5 KBįIGURE S1 Ag and Au NPs-CM do not affect macrophage viability in vitro. Chiorean, International Journal of Latest Research. 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. NPs-CM appear to repress NF-κB activation in macrophages, inhibiting the production of pro-inflammatory factors with causal role in psoriasis. Immunofluorescence confirmed that nanoparticles significantly reduced CD68-positive macrophages and their IL-12 and TNF-α production in human psoriasis plaques. Incubation of pro-inflammatory macrophages with nanoparticles significantly decreased the release of NO, IL-12 and TNF-α. 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. 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. But after a few more days, tiny buds appear at the end of short twiggy side shoots.New biomaterials based on nanoparticles (NPs) carrying polyphenols-rich extracts ( Cornus mas) recently showed promising anti-inflammatory activity in psoriasis. It’s smart - it knows that one swallow does not make a spring. On the first warm days the shrub remains bare. It is my thermometer, gauging my level of optimism, telling me whether spring is here or not. It is my surrogate swimmer, cautiously putting a toe in the water, then pulling it back. Still, the main reason I like my Cornelian cherry is the act it puts on at this time of year. In fact, the only thing I can remember doing to mine is pruning out dead wood, a pleasant task whenever the sun is shining. It isn’t fussy about the soil either, although I’m sure that a fertile soil and a modicum of water will help it grow faster. It isn’t particular, growing well in sun or part shade. They are dark green and slightly glossy in summer occasionally they will colour in autumn but overall they are so uninteresting that I can’t find a single photo that shows them in any season.įor one thing, it is pest-free - and that’s a big plus in an organic garden. The leaves aren’t much to write home about either. (Will it become better with age? I hope so.) The branches are upright and the short trunk needs to be pruned up if you want to show off the exfoliating bark which, on my specimen, is nothing to write home about. I planted the one you see in the photo above in 2005 and in eleven years, it has barely doubled in size. This picture isn’t very good and it’s the best I have.Ĭornus mas is a slow-growing deciduous shrub or small tree.
