In this editorial, we examine a paper by Koizumi , on the role of peroxisome proliferator-activated receptor (PPAR) agonists in alcoholic liver disease (ALD). The study determined whether elafibranor protected the intestinal barrier and reduced liver fibrosis in a mouse model of ALD. The study also underlines the role of PPARs in intestinal barrier function and lipid homeostasis, which are both affected by ALD. Effective therapies are necessary for ALD because it is a critical health issue that affects people worldwide. This editorial analyzes the possibility of PPAR agonists as treatments for ALD. As key factors of inflammation and metabolism, PPARs offer multiple methods for managing the complex etiology of ALD. We assess the abilities of PPARα, PPARγ, and PPARβ/δ agonists to prevent steatosis, inflammation, and fibrosis due to liver diseases. Recent research carried out in preclinical and clinical settings has shown that PPAR agonists can reduce the severity of liver disease. This editorial discusses the data analyzed and the obstacles, advantages, and mechanisms of action of PPAR agonists for ALD. Further research is needed to understand the efficacy, safety, and mechanisms of PPAR agonists for treating ALD.

L. is known in Europe for its cardioactivity-also in interrelation with known risk factors of the metabolic syndrome-just as Houtt. in East Asia; however, up to now, no active constituents could be identified.

This article discusses the recent study written by Koizumi . Alcohol-associated liver disease (ALD) is a major cause of liver-related morbidity and mortality, which is driven by complex mechanisms, including lipid accumulation, apoptosis, and inflammatory responses exacerbated by gut barrier dysfunction. The study explored the therapeutic potential of elafibranor, a dual peroxisome proliferator-activated receptor alpha/delta agonist.

Background & Aims: Lanifibranor is a pan-PPAR agonist that improves glucose/lipid metabolism and reverses steatohepatitis and fibrosis in adults with MASH. We tested its effect on insulin resistance at the level of different target tissues in relationship to change in intrahepatic triglyceride (IHTG) content.
Methods: This phase 2, single center, study randomized (1:1) 38 patients with T2D and MASLD to receive lanifibranor 800 mg or placebo for 24 weeks.

While cognitive impairment has been documented in ulcerative colitic patients, the possible influence of central β3-adrenergic receptor (β3-AR) signaling on this extraintestinal manifestation remains unclear. Previously, we identified an imperative role for mirabegron (MA) as an agonist of β3-AR, in decreasing the BACE-1/beta-amyloid (Aβ) cue in the colons of UC rats. Consequently, we investigated its therapeutic potential for alleviating cognitive impairment associated with UC.

Portal hypertension (PH) can cause severe complications in patients with advanced chronic liver disease (aCLD). The pan-peroxisome proliferator-activated receptor (pan-PPAR) agonist lanifibranor reduces portal pressure in preclinical models of aCLD. Since the effect on PH might be secondary to fibrosis improvement, we investigated the effect of lanifibranor on PH, hepatic and splanchnic angiogenesis in mouse models of fibrotic and prehepatic non-fibrotic PH.
