The peroxisome proliferator-activated receptors (PPARs) are nuclear receptors involved in the regulation of the metabolic homeostasis and therefore represent valuable therapeutic targets for the treatment of metabolic diseases. The development of more balanced drugs interacting with PPARs, devoid of the side-effects showed by the currently marketed PPARγ full agonists, is considered the major c...

Several decades ago, fibrates were approved for the treatment of dyslipidemia, whereas thiazolidinediones were screened in animal models to improve glucose homeostasis and were subsequently developed for the treatment of type 2 diabetes mellitus. Relatively recently, these drugs were found to act via peroxisome proliferator-activated receptors, nuclear receptors that control lipid metabolism an...

Peroxisome proliferator-activated receptors (PPARs) and retinoid X receptors (RXRs) are members of the intracellular receptor superfamily. PPARs bind to peroxisome proliferator-response elements (PPREs) as heterodimers with RXR and as such activate gene transcription in response to activators. Fibrates like gemfibrozil are well-known PPARalpha activators and are used in the treatment of hyperli...

Peroxisome proliferator-activated receptors (PPARs) are nuclear receptors of transcription factors composed of three family members: PPARα, PPARβ/δ and PPARγ. This study was aimed to evaluate the role of PPARs in the estradiol production via follicle stimulating hormone (FSH) in the ovine Sertoli cells. At the first step, transcripts of PPARα, PPARβ /δ and PPARγ were evaluated by quantitative r...

Metabolic syndrome (MS), a condition characterized by multiple related clinical disorders including insulin resistance, central obesity, hyperlipidemia, hypertension, and heart disease, is an increasingly prevalent disease in industrialized societies. The intense research interest in the peroxisome proliferator-activated receptors (PPARs), by both the pharmaceutical industry and academia, stems...

Peroxisome proliferator-activated receptors (PPARs) play an important role in regulating both glucose and lipid metabolism. Agonists for both PPARgamma and PPARgamma have been used to treat dyslipidemia and hyperglycemia, respectively. In addition to affecting glucose metabolism, PPARgamma agonists also regulate lipid metabolism. In this review, we will focus on the randomized clinical trials t...

Abstract: Macrophages, a key component of the innate defense against pathogens, participate in the initiation and resolution of inflammation, and in the maintenance of tissues. These diverse and at times antithetical functions of macrophages are executed via distinct activation states, ranging from classical to alternative to deactivation. Because the dysregulation of macrophage activation is p...

Peroxisome proliferator-activated receptors (PPARs) regulate energy metabolism and hence are therapeutic targets in metabolic diseases such as type 2 diabetes and non-alcoholic fatty liver disease. While they share anti-inflammatory activities, the PPAR isotypes distinguish themselves by differential actions on lipid and glucose homeostasis. In this Review we discuss the complementary and disti...

Strategies to improve the viability of steatotic livers could reduce the risk of dysfunction after surgery and increase the number of organs suitable for transplantation. Peroxisome proliferator-activated receptors (PPARs) are major regulators of lipid metabolism and inflammation. In this paper, we review the PPAR signaling pathways and present some of their lesser-known functions in liver rege...
