IL1B and metabolic dysfunction-associated steatotic liver disease: The same results were obtained in our study, where NAR, especially nanoparticle-loaded NAR significantly increased the levels of endogenous antioxidant enzyme GSH and decreased the levels of lipid peroxides MDA, while significantly decreasing the levels of inflammatory factors (TNF-α, IL-6 and IL-1β), which led to the improvement of liver function in MASLD mice.
