In neurological disorders, pathological lesions in the central nervous system (CNS) may be globally dispersed throughout the brain or localized to specific regions. Although native neural stem cells (NSCs) are present in the adult mammalian brain, intrinsic self-repair of injured adult CNS tissue is inadequate or ineffective. The brain's poor regenerative ability may be due to the fact that NSCs are restricted to discrete locations, a Read More

Recent findings indicate an important role for RNA-mediated gene expression in motor neuron diseases, including ALS (amyotrophic lateral sclerosis) and SMA (spinal muscular atrophy). ALS, also known as Lou Gehrig’s disease, is an adult-onset progressive neurodegenerative disorder, whereby SMA or “children’s Lou Gehrig’s disease” is considered a pediatric neurodevelopmental disorder. Despite the difference in gene Read More

The maintenance of appetite at proper levels, depending on the energy status, is important; otherwise abnormal appetite may cause a series of disorders, such as anorexia, hyperphagia, obesity, and its complications (diabetes mellitus, hypertension, cardiovascular disease, and fatty liver disease). Hypothalamic AMPactivated protein kinase (AMPK) integrates diverse hormonal and nutritional signals to regulate food intake a Read More

The S100A9 protein is an important proinflammatory factor of innate immunity that has been proposed to participate in inflammation associated with the pathogenesis of Alzheimer’s disease. Here, we provide insights into the potential roles of extracellular S100A9 in the interaction with the immune response in human THP-1 monocytic cells that have been challenged with amyloid β1-42 (Aβ1-42) monomers instead of oligom Read More

Neuregulin-1 (NRG-1) is a ligand of the epidermal growth factor receptor (erbB), and its interaction involves activation of the glutamatergic N-methyl-Daspartate receptor, which increases the expression of the β2 subunit of the γ- aminobutyric acid receptor and subunits of the nicotinic acetylcholine receptor. In the dentate gyrus of 14-month-old Tg2576 mice, NRG-1 was strongly expressed compared with age-matched Read More

Erythropoietin (EPO) has been shown to be a key cytokine in the production of erythrocytes from erythroblasts. Recently, attempts have been made to adopt EPO as a drug target for neuroprotection in selected neurological pathologies. In the current study, a novel EPO-derived peptide which mimics the weak binding site of EPO to its receptor (MK-X) was generated. Experimental results demonstrated that MK-X was able to am Read More

We previously demonstrated that dehydroevodiamine•HCl (DHED), which was purified from Evodia rutaecarpa Bentham (Rutaceae), has beneficial effects on memory impairment and neuronal damage in three disease models. To investigate the preventive action of DHED in Alzheimer’s disease (AD), a progressive neurodegenerative disorder characterized by memory decline, amyloid-β (Aβ) protein-containing neuritic plaques an Read More

The role of phosphatidylinositol 3-kinase linked mammalian target of rapamycin (mTOR) pathway hyperactivation is well established in cancer pathogenesis. Several molecules inhibiting mTOR pathway, leading to inhibition of protein synthesis responsible for angiogenesis of tumor cells have emerged out to be potential anticancers. Similar hyperactivation of mTOR pathway has also reported in epilepsy during latent pha Read More

Ghrelin production occurs in the gastrointestinal tract with the greatest concentration in the fundus of the stomach, which accounts for approximately 75- 80% of circulating ghrelin levels. Desacyl ghrelin has been suggested to be involved in the regulation of energy homeostasis because of its ability to cross the blood-brain barrier and to induce increased neuronal activity in the hypothalamic arcuate nucleus. The Read More

Neurodegenerative diseases are the leading cause of disability in the elderly. Growing evidence suggests that oxidative stress, which is associated with aging, is the basis of most neurodegenerative disorders; and polyphenols, acting as antioxidant agents, reduce the risk of neurodegenerative diseases. Quercetin is a flavonoid occurring in many plant foods commonly consumed as part of a regular diet. It shows a number of bio Read More

The prevalence of central nervous system trauma, neurodegenerative and psychiatric diseases has significantly increased in recent years. Most of these diseases show multifactorial causes and several progression mechanisms. The search for a medication which positively interferes in these mechanisms and thereby changes the course of these diseases is of great scientific interest. The aim of the present review is to assess Read More

Eleven compounds belonging to the chalcone family were tested for their ability to activate and subsequently desensitize the rat transient receptor potential ankyrin 1 cation channel, subfamily A, member 1 (TRPA1) in a heterologous expression system. Four of the tested compounds were more potent than the TRPA1 agonist mustard oil, and showed also a strong desensitizing effect. Some chalcone compounds were not pungent Read More

Background: Spontaneously hypertensive rats (SHR) represent a model of hypertension and vascular injury. In the past decade, SHR were also considered as a model of vascular dementia. Several studies have shown that cerebrovascular changes in SHR may mimic brain vascular diseases of hypertensive individuals. Vascular and cerebrovascular changes during hypertension are often linked to inflammatory processes. Infla Read More

Vascular dementia (VD) is the second most common cause of cognitive impairment in the elderly population. Our study aims to investigate the neuroprotective effects of glycyrrhizic acid (GA), a major active constituent of Glycyrrhiza glabra root, in a VD rat model induced by permanent occlusion of the bilateral common carotid arteries. Spatial cognitive function was examined by the Morris water maze test and synaptic Read More
