| dc.abstract.en | Background: Growing evidence highlights the beneficial effects of flavonoids, including anthocyanins, as key components in reducing cardiovascular risk, and emphasizes that incorporating anthocyanin-rich fruits into the daily diet significantly impacts public health. Methods: The effect of bioactive polyphenols from raspberry fruit (RBF) on molecular pathways in inflammation was studied in activated RAW 264.7 macrophages and their protective potential against endothelial dysfunction was analyzed using TNF-α-induced human umbilical vein endothelial cells (HUVECs). Results: The results have shown that RBF extract, along with its anthocyanin and polyphenol fractions, has a significant anti-inflammatory effect in macrophage cell culture by inhibiting the LPS-induced expression of pro-inflammatory genes, including IL-6, IL-1β, TNF-α, and NF-κB. Moreover, RBF and both fractions have demonstrated a protective effect on endothelial function by decreasing the expression of several inflammation-related genes and adhesion molecules, such as IL-6, IL-1β, VCAM-1, ICAM-1, and SELE, in TNF-α-induced HUVECs. Conclusions: The consumption of RBF and/or polyphenol-rich extracts may help prevent the onset of early atherosclerosis. This is attributed to their ability to improve inflammation status and enhance vascular endothelial function. Given the strong anti-inflammatory properties of RBF, incorporating them into a daily diet could significantly reduce the risk of non-communicable diseases related to inflammation. | |
