Beneficial effects of natural compounds on experimental liver ischemia-reperfusion injury.

Food Funct 2021 May;12(9):3787-3798

Molecular and Clinical Pharmacology Program, Institute of Biomedical Sciences, Faculty of Medicine, University of Chile, Santiago, Chile.

Liver ischemia-reperfusion injury (IRI) is a phenomenon inherent to hepatic surgery that severely compromises the organ functionality, whose underlying mechanisms involve cellular and molecular interrelated processes leading to the development of an excessive inflammatory response. Liver resident cells and those recruited in response to injury generate pro-inflammatory signals such as reactive oxygen species, cytokines, chemokines, proteases and lipid mediators that contribute to hepatocellular necrosis and apoptosis. Besides, dying hepatocytes release damage-associated molecular patterns that actívate inflammasomes to further stimulate inflammatory responses leading to massive cell death. Read More

Fenofibrate (a PPAR-α Agonist) Administered During Ethanol Withdrawal Reverts Ethanol-Induced Astrogliosis and Restores the Levels of Glutamate Transporter in Ethanol-Administered Adolescent Rats.

Front Pharmacol 2021 20;12:653175. Epub 2021 Apr 20.

Institute of Biomedical Sciences, Faculty of Health Sciences, Universidad Autónoma de Chile, Santiago, Chile.

High-ethanol intake induces a neuroinflammatory response, which has been proposed as responsible for the maintenance of chronic ethanol consumption. Neuroinflammation decreases glutamate transporter (GLT-1) expression, increasing levels of glutamate that trigger dopamine release at the corticolimbic reward areas, driving long-term drinking behavior. The activation of peroxisome proliferator-activated receptor alpha (PPARα) by fibrates inhibits neuroinflammation, in models other than ethanol consumption. Read More

Mefepronic acid is associated with a decrease in serum liver enzyme activities in dogs with suspected hepatopathy.

Vet Med Sci 2021 May 6. Epub 2021 May 6.

Department of Veterinary Science, University of Parma, Italy.

Although suspected hepatopathy in dogs can be assessed by the blood levels of both liver enzyme activities and functional liver parameters, very often the precise diagnosis of primary or secondary hepatobiliary diseases can remain uncertain. Therefore, in a number of patients, the therapeutic intervention has the purpose of slowing the progression of fibrosis and provide for optimal hepatic support. Recently the PPARs (peroxisome proliferator-activated receptors) have been identified as a family of hepatic nuclear hormonal receptors, involved in the regulation of lipid and glucose metabolism.

PPARɣ drives IL-33-dependent ILC2 pro-tumoral functions.

Nat Commun 2021 05 5;12(1):2538. Epub 2021 May 5.

Department of Pathology and Immunology, University of Geneva, Geneva, Switzerland.

Group 2 innate lymphoid cells (ILC2s) play a critical role in protection against helminths and in diverse inflammatory diseases by responding to soluble factors such as the alarmin IL-33, that is often overexpressed in cancer. Nonetheless, regulatory factors that dictate ILC2 functions remain poorly studied. Here, we show that peroxisome proliferator-activated receptor gamma (PPARγ) is selectively expressed in ILC2s in humans and in mice, acting as a central functional regulator. Read More

R&D Division, Kyoto Pharmaceutical Industries, Ltd.

Peroxisome proliferator-activated receptor γ (PPARγ) modulators are expected to exert anti-diabetic effects without PPARγ-related adverse effects, such as fluid retention, weight gain, and bone loss. The present study showed that the novel tetrazole derivative KY-903 exerted similar selective PPARγ partial agonist properties to INT-131, a known PPARγ modulator, in transactivation assays, and decreased plasma glucose and triglyceride levels with increases in adiponectin levels in diabetic KK-Ay mice. These effects were similar to those of pioglitazone. Read More
