The increased prevalence of neurodegenerative diseases, especially during the COVID-19 outbreak, necessitates search for natural immune- and cognitive-enhancing agents. 10-Hydroxy-trans-2-decenoic acid (10-H2DA), main fatty royal jelly, has several pharmacological activities. Given fundamental role astrocytes in regulating immune responses central nervous system, we used cortical to examine eff...

Neurotrophins constitute a group of growth factor that exerts important functions in the nervous system vertebrates. They act through two classes transmembrane receptors: tyrosine-kinase receptors and p75 neurotrophin receptor (p75NTR). The activation p75NTR can favor cell survival or apoptosis depending on diverse factors. Several studies evidenced link between pathogenesis prion diseases. In ...

Multiple sclerosis (MS) is a chronic inflammatory demyelinating and neurodegenerative disease of the central nervous system (CNS) with unknown etiology. It was recently suggested that autoimmunity, which had long been considered to be destructive in MS, might also play a protective role in the CNS of MS patients. Neurotrophins are polypeptides belonging to the neurotrophic factor family. While ...

Alveolar macrophages are known to express a variety of growth factors and neurotrophins. Fibroblast growth factor-1 (FGF-1) is abundantly present in the lung and has mitogenic and neurotrophic activities similarly to neurotrophins. In order to determine whether FGF-1 associates with neurotrophins in alveolar macrophages, we investigated the immunocytochemical colocalization of FGF-1 with neurot...

The neurotrophins brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3) and their receptors trkB and trkC, respectively, are expressed in the locus coeruleus (LC) and ventral tegmental area (VTA), brain regions known to be involved in opiate addiction. Previously, administration of exogenous neurotrophins has been shown to oppose effects of chronic morphine treatment on LC and VTA ...

Neurotrophins such as nerve growth factor (NGF) regulate neuronal survival during development and are neuroprotective in certain models of injury to both the peripheral and the central nervous system. Although many effects of neurotrophins involve long-term changes in gene expression, several recent reports have focused on rapid effects of neurotrophins that do not involve synthesis of new gene...

Traumatic brain injury (TBI) is a major cause of morbidity and mortality among young individuals worldwide. Understanding the pathophysiology of neurotrauma is crucial for the development of more effective therapeutic strategies. After the trauma occurs, immediate neurologic damage is produced by the traumatic forces; this primary injury triggers a secondary wave of biochemical cascades togethe...
