Aim
To isolate PDEN from goldenberry fruits and evaluate its anti-inflammatory potential in macrophage polarization.
Conclusion
GDEN showed anti-inflammatory potential through the ability to reduce M1 macrophages product and promote M2 polarization.
Methods
GDEN were isolated by centrifugation and precipitation methods. LPS-induced RAW 264.7 cells were treated with GDEN before being evaluated with nitric oxide production assay and flow cytometry of CD80 and CD209.
Objective
Overpopulated M1 macrophages can trigger chronic inflammation. Plant-derived exosome-like nanoparticles have been reported to show beneficial bioactivities. Aim: To isolate PDEN from goldenberry fruits and evaluate its anti-inflammatory potential in macrophage polarization.
Results
GDEN averaged 227.7 nm in size and spherical-shaped. GDEN 40 μg/ml decreased NO production in LPS-induced cells. Flow cytometry showed that CD209 (M2 marker) positive cells were up-regulated after being treated with 20 μg/ml GDEN.
