Zusammenfassung der Projektergebnisse
In summary, the results of the current study support the concept that dietary LA, a ω-6-PUFA, exacerbates ethanol-induced liver injury and provides evidence that the increase in OXLAM production and promotion of an OXLAM-mediated pro-inflammatory response might be one of the underlying mechanisms. Strategies to decrease LA consumption through dietary modifications may be an effective approach to reduce ethanol-induced OXLAMs and to attenuate ALD.
