The receptor mechanisms mediating the retrograde axonal transport of the neurotrophins have been investigated in adult rats. We show that transport of the TrkB ligands NT-4 and BDNF to peripheral neurons is dependent on the low affinity neurotrophin receptor (LNR). Pharmacological manipulation of LNR in vivo using either an anti-LNR antibody or a soluble recombinant LNR extracellular domain com...

Neurotrophins have been previously mentioned as potential factors that may alter human growth and result in fetal restriction (FGR). As neural factors, neurotrophins promote brain development plasticity a significant effect on the synaptic transmission, although actual mechanisms of their action not completely investigated. Several articles published this field denoting importance biomarkers de...

The neurotrophin hypothesis proposes that neurotrophins participate in activity-induced modification of synaptic transmission. Increasingly, evidence indicates that the synthesis, secretion and actions of neurotrophins on synaptic transmission are regulated by electrical activity and that neurotrophins themselves can acutely modify synaptic efficacy. Neurotrophins appear to exert either a permi...

The neurotrophins nerve growth factor, brain-derived neurotrophic factor, NT-3 (neurotrophin 3) and NT-4 are known for regulating neuron development, function and survival. Beyond this, neurotrophins were found to exert multiple effects on non-neuronal cells such as immune cells, smooth muscle and epithelial cells. In allergic asthma, airway inflammation, airway obstruction, AHR (airway hyperre...

Previous studies using transfected cells have indicated that the mammalian receptor tyrosine kinase trkB binds the neurotrophins brain-derived neurotrophic factor, neurotrophin-3 and neurotrophin-4. However, most studies demonstrating that these neurotrophins prevent the death of embryonic neurons and have specific neuronal receptors have been performed with chick neurons. In order to explore t...

The neurotrophin gene family comprises four structurally related basic proteins, NGF, BDNF, NT-3 and NT-4/5. Despite high structural homology, these neurotrophins operate via different high-affinity membrane receptors, differ in target specificity, patterns of spatial and temporal distribution and responses to injury of the neuronal tissue. Based on the recent data, some aspects of BDNF and NT-...

CONTEXT It is worth noting that islets and betaTC6-F7 cells share a common pattern of expression of neurotrophins and neurotrophin receptors. Recently, several studies have hypothesized a role for nerve growth factor in pancreatic development and maturation, suggesting that nerve growth factor may be a survival factor for pancreatic beta-cells. OBJECTIVE The aim of the present study was to in...

Background Data: Neurotrophins/peptide mixture is a porcine brain-derived peptide preparation with pharmacodynamic properties similar to those of endogenous neurotrophic factors. No study has evaluated the postoperative role neurotrophins/peptide in recovery postdiscectomy motor weakness. Purpose: This aims evaluate effect treatment on L5 weakness after lumbar discectomy compared placebo. Study...
