The Glucagon-like peptide-1 (GLP-1) receptor is expressed in the lung having a very important role in the modulation of the Angiotensin Converting Enzymes (ACEs). ACE1 cleaves angiotensin-I into angiotensin-II, which is converted by ACE2 to Ang(1-7). Ang(1-7) has vasodilating effects. The Idiopathic Pulmonary Fibrosis (IPF) is characterized by excessive extracellular matrix deposition disrupting the alveolar architecture and physiology. IPF develops by a sequence of inflammati...

The Glucagon-like peptide-1 receptor is widely expressed in diverse tissues including the liver. GLP-1 contributes itself to the regulation of glucose homeostasis and has important effects in lipid metabolism even preventing liver steatosis induced by high fat diets.The aim of this study was to analyse the short-term effects of liraglutide on key enzymes of the hepatic energy metabolism.Thirty-six Sprague-Dawley young adult male ra...

Adverse events during gestation in rodents, results in an enhancement of immune function, including elevated levels of inflammatory cytokines in the brain. Liraglutide is a GLP-1 receptor agonists known to exert neuroprotective effects in brain. The aim of this study was to elucidate if liraglutide given to food restricted (FR) pregnant rats may prevent the deleterious effects of FR in the hippocampal inflammatory status of male and female pups at 21 days of age (D21). 20 Spra...

Acute lung injury (ALI) is characterized by endothelial and epithelial damage, followed by inflammatory. Glucagon-like peptide-1 (GLP-1) is a gut-produced hormone with insulinotropic effects. GLP-1 receptor is expressed in the lung, and there implicated in the synthesis of surfactant proteins. We have previously shown that liraglutide (LIR), a GLP-1 receptor agonist, restores surfactant protein-B (SPB) levels, a limiting factor for survival, and also angiotensin converting enz...

Food restriction (FR) of mothers during the perinatal period, can lead to disorders in emotional behaviors at offspring. GLP-1 may play a role in the regulation of anxiety-like behavior in rodents. The aim of this study was to asses if Liraglutide (a GLP-1 receptor agonist; LIR) given to pregnant rats may prevent the deleterious effects of FR in the anxiety-like behavior in pups at 21 days and two months of age males.Twenty-five pregnant Sprague-Dawley r...

The skeletal muscle expresses the Glucagon-like Peptide 1 (GLP-1) receptor, although its effects in this tissue are not well known. Muscles are a major sink of energy substrates. The aim of our study was to examine the mid-term effect of Liraglutide (LIRA), a GLP-1 receptor agonist, in the expression of molecular indicators of the metabolic activity of the muscle, which includes enzymes, transporters, and intracellular signals. Twenty young Spague-Dawley male rats (350-400 g) ...

Idiopathic pulmonary fibrosis (IPF) is an excessive accumulation of fibrous filaments in the extracellular matrix (ECM), in response to an inflammatory reaction that disrupts normal lung architecture and physiology. Collagen is the most abundant fibrous protein in the ECM. The GLP-1 receptor is highly expressed on lung tissue, where his activation plays an essential role in the synthesis and secretion of surfactant proteins. The objective of this study was to elucidate the eff...

Anaerobic threshold (AT) is defined as the point of maximum intensity at which lactate is being produced but does not accumulate in blood during exercise. Training at this intensity is common in athletes. Lactate is currently regard as indicator of effort intensity. It is usually quantified by reflectometry of capillary blood. This procedure although not very invasive, may be annoying during repeated measurements. Saliva is proposed as an alternative sample.<p class="abste...

Maternal food restriction during late pregnancy and lactation, increases the risk of glucose intolerance and metabolic diseases such as diabetes & obesity in rats. Liraglutide is a GLP-1 receptor agonists administered for treating DM2. The aim of this study was to elucidate if liraglutide given to pregnant rats may prevent the deleterious effects of malnourishment in male pups analyzed at 21 days of age.Twenty eight Sprague-Dawley pregnant rats were ...
