Investigating the effectiveness of liposomal formulations in managing hyperlipidemia is essential. Resveratrol (RES)-loaded nanoliposomes present a promising new approach for hyperlipidemia treatment. In this study, we investigated the anti-hyperlipidemic potential of RES-loaded nanoliposomes in high-fat diet (HFD)-fed rats. The nanoliposomes were prepared using a thin-film hydration method. According to transmission electron microscopy (TEM) and dynamic light scattering (DLS) results, the mean size of prepared RES-loaded nanoliposomes were about 42 nm and 68 nm, respectively, with a zeta potential of -65.6 mV. The entrapment efficiency and loading content were 83.78% and 14.25%, respectively. Additionally, the RES-loaded nanoliposomes exhibited controlled release kinetics compared to the free RES form. Moreover, in a hyperlipidemic rat model induced by an HFD, orally administered RES-loaded nanoliposomes significantly reduced total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), very low-density lipoprotein cholesterol (VLDL-C), and triglycerides (TG), while concurrently increasing high-density lipoprotein cholesterol (HDL-C) levels. Additionally, liver damage induced by HFD was alleviated by RES-loaded nanoliposomes. The expression levels of Toll-like receptor 3 (TLR3) and TIR domain-containing adaptor-inducing interferon-β (TRIF) were assessed using fluorescence immunohistochemistry. Notably, RES-loaded nanoliposomes significantly reduced the expression of these protein. The effect of RES-loaded nanoliposomes was measured on body weight of HFD rats, demonstrting RES-loaded nanoliposomes hold promise for weight management.
