The molecular mechanisms of action of PPAR-γ agonists in the treatment of corneal alkali burns (Review)

چکیده
Corneal alkali burns (CAB) are characterized by injury-induced inflammation, fibrosis and neovascularization (NV), and may lead to blindness. This review evaluates the current knowledge of the molecular mechanisms responsible for CAB. The processes of cytokine production, chemotaxis, inflammatory responses, immune response, cell signal transduction, matrix metalloproteinase production and vascular factors in CAB are discussed. Previous evidence indicates that peroxisome proliferator-activated receptor γ (PPAR-γ) agonists suppress immune responses, inflammation, corneal fibrosis and NV. This review also discusses the role of PPAR-γ as an anti-inflammatory, anti-fibrotic and anti-angiogenic agent in the treatment of CAB, as well as the potential role of PPAR-γ in the pathological process of CAB. There have been numerous studies evaluating the clinical profiles of CAB, and the aim of this systematic review was to summarize the evidence regarding the treatment of CAB with PPAR-γ agonists.

Compare the Effect of Eicosapentaenoic Acid and Oxidized Low-Density Lipoprotein on the Expression of CD36 and Peroxisome Proliferator-Activated Receptor Gamma
Background: There is evidence that CD36 promotes foam cell formation through internalizing oxidized LDL (ox-LDL) into macrophages therefore, it plays a key role in pathogenesis of atherosclerosis. In addition, CD36 expression seems to be mediated by nuclear receptor peroxisome proliferator-activated receptor gamma (PPAR-γ). The aim of the present study was to evaluate and compare the effect of ...

Introduction: The inflammatory response requires a coordinated integration of various signaling pathway including cyclooxygenase (COX). COX catalyzes the formation of prostaglandins from arachidonic acid. Among prostaglandins, 15-Deoxy-D12, 14-prostaglandin J2 (15d-PGJ2), an endogenous ligand of Peroxisome proliferator-activated receptor-gamma (PPAR-γ), has been demonstrated to have anti-inflam...
متن کاملPeroxisome proliferator-activated receptors: Targets for the treatment of metabolic illnesses (Review).
Peroxisome proliferator-activated receptors (PPARs) belong to a family of transcription factors of which three isotypes, PPARα, PPARδ (β) and PPARγ, are known. These play a central role in regulating intermediate metabolism and in incidences of inflammation. In recent years, a greater understanding of their mechanisms of action and their effects, principally in the management of cardiovascular ...
متن کاملThe Effect of Biochanin A as PPAR γ agonist on LDL Particles Diameter and Type 2 Diabetic Dyslipidemia
Background and Aims: Small dense low-density lipoproteins (sd-LDL) particles are smaller and heavier than typical LDL ones. They can penetrate into the endothelium of coronary arteries more easily because of their small size. Diabetes mellitus is accompanied by dyslipidemia such as increasing concentration of plasma very low density lipoprotein and sd-LDL. Peroxisome proliferator activated rec...
