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. 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. 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. Conclusion: GDEN showed anti-inflammatory potential through the ability to reduce M1 macrophages product and promote M2 polarization.
