It has been reported that ghrelin exerts anticonvulsive effects in models of epilepsy. In this study we aimed to characterize the anticonvulsive activity of ghrelin and other growth hormone secretagogue receptor 1a (GHSR(1a)) ligands in rats exposed to status epilepticus induced by pilocarpine or kainate. Firstly, in three independent experiments, before(More)
Ghrelin is a 28-amino-acid gastric peptide that potently stimulates growth hormone (GH) secretion in vivo and in vitro. Ghrelin-expressing cells have been found in the oxyntic region of the stomach and in the arcuate nucleus of the hypothalamus. The aim of this work was to investigate the regional distribution and developmental changes in ghrelin mRNA(More)
Data from Alzheimer's disease (AD) patients and AD animal models demonstrate the accumulation of inflammatory microglia at sites of insoluble fibrillar beta-amyloid protein (fAbeta) deposition. It is known that fAbeta binds to CD36, a type B scavenger receptor also involved in internalization of oxidized low-density lipoprotein (LDL), and initiate a(More)
The hypothalamic-pituitary-adrenal (HPA) axis is a major integrated system that maintains body homeostasis by regulating the neuroendocrine and sympathetic nervous systems and modulating immune function. It is well established that the central nervous system (CNS) integrates responses to different stimuli secreting a specific corticotropin-releasing hormone(More)
In models of status epilepticus ghrelin displays neuroprotective effects mediated by the growth hormone secretagogue-receptor 1a (GHS-R1a). This activity may be explained by anticonvulsant properties that, however, are controversial. We further investigated neuroprotection and the effects on seizures by comparing ghrelin with a more effective GHS-R1a(More)
TLQP-21 (TLQPPASSRRRHFHHALPPAR) is a multifunctional peptide that is involved in the control of physiological functions, including feeding, reproduction, stress responsiveness, and general homeostasis. Despite the huge interest in TLQP-21 biological activity, very little is known about its intracellular mechanisms of action. In microglial cells, TLQP-21(More)
Ghrelin and the synthetic growth hormone secretagogues (GHSs) activate a G-protein-coupled receptor (GHS-R) originally cloned from the pituitary, but which is also expressed in the hypothalamus, in other areas of the brain and in numerous peripheral tissues. Several studies have shown that growth hormone (GH)-releasing hormone (GHRH) is necessary for GHSs(More)
